Body widely oval, sexually dimorphic in shape; males widely rounded in dorsal view, without pronouncing shoulders (e.g., Fig. 52a, b, 60e); females more elongate, with pronouncing shoulders and elytra (rather) strongly narrowing posteriad (e.g., Fig. 52e, g, 60d). Body length 2.0– 4.5 mm. Body coloration often with distinct pattern of pale reddish to yellowish and dark brown or black spots (in this case beetles appearing dark with pale pattern or pale with dark pattern according to the extent of pale/dark parts); in some species body more or less uniformly pale reddish to dark brown (see P. apicatum, P. coomani and P. rugosum).</p><p>Head. Anterior margin of clypeus convex medially, strongly angulate laterally, bearing rather wide and very distinct rim. Frontoclypeal sutures angulate, lateral portions very distinct as transverse ridges arising above antennal bases and reaching submedially, median portions weakly developed or totally missing. Median portion of frons not elevated above lateral portions. Eyes moderately large, separated by 5–6× the width of one eye in dorsal view. Labrum membraneous, partly concealed by clypeus. Maxillary palpomere 2 club-like, strongly widened distally, palpomere 3–4 thin, palpomere 4 spindle-like (Fig. 2); maxilla of male with sucking disc (Figs. 1, 3). Mentum (Figs. 1, 4) transverse, ca. 2.5× as wide as long; lateral margin angulate slightly before posterolateral corner; anterior margin slightly concave medially, anterolateral corners rounded; transverse groove lying along anterior margin present medially; punctation consisting of coarse shallow punctures elongate anteriad and therefore forming low longitudinal ridges in anterior portion. Submentum densely pubescent, ridges arising from posterior margin of maxillary groove absent. Posterior tentorial pits present, minute; gular sutures weakly developed, slightly diverging posteriad; gula carinate medially in posterior portion, bearing coarse setiferous punctures (Fig. 4). Antenna with 9 antennomeres (Fig. 5); scapus strongly arcuate, bearing a distinct longitudinal ridge dorsally; pedicel ca. as long as antennomere 3, antennomeres 3–5 gradually decreasing in length; cupula small; antennal club compact, densely pubescent, widely rounded at apex, lacking any fields of special sensorial structures.</p><p>Prothorax. Pronotum arcuate on posterior margin, shallowly bisinuate on anterior margin; lateral portions deflexed and therefore seen ventrally (Fig. 8), false pronotal margin absent, lateral margin of pronotum angular in lateral view (Fig. 7). Pronotal punctation consisting of large shallow punctures intermixed among fine ground punctation (Figs. 12–14). Series of large punctures along posterior margin present. Prosternum highly elevated into a subpentagonal plate medially (Figs. 8–11), the plate sharply to indistinctly carinate medially, bearing coarse punctures; anterior margin of prosternum constricted just laterally of the plate, deep pits laterally of lateral margins of the plate present (Fig. 7). Antennal grooves very distinct, large, laterally reaching deflexed lateral margin of pronotum (Fig. 8). Profurcal arms short, reaching ca. ventral third of prothoracic height, leaf-like, strongly asymmetrical in shape, protruding of the posterior foramen of prothorax (Fig. 6). Additional ridge below posterior pronotal margin present, very distinct, reaching lateral margin of hypomeron.</p><p>Mesothorax. Mesoventrite much shorter than metaventrite, distinctly inclined and therefore not lying in the same plane as mesepimera (Fig. 15). Median portion of mesoventrite elevated into preepisternal plate, the plate triangular in shape, slightly wider than long (Figs. 15–19), bearing very distinct rim on anterolateral margins; posterior margin of the plate widely contacting metaventral process. Grooves for reception of procoxae developed, large, reaching anterior margin of mesocoxal cavities (Fig. 15). Mesepimeron with very distinct oblique ridge laterally. Mesocoxal cavities widely isolated from each other. Mesofurca not examined. Scutellar shield triangular, slightly longer than wide (Fig. 23). Elytron with 10 elytral series; all elytral intervals of the same height; lateral portions of elytron not deflexed. Epipleuron totally missing except very basally.</p><p>Metathorax. Metaventrite (Fig. 15) without elevate median portion; metaventral process wide, widely attaching posterior margin of preepisternal elevation of mesothorax. Anterior margin of metaventrite with distinct anterior ridge lying subparallel to posterior margin of mesocoxal cavity, defining rather wide marginal bead, but disappearing submedially. Femoral lines developed, complete, reaching anterolateral corners of metaventrite. Anepisternum extremely narrow anteriorly, slightly widening posteriad (Fig. 15). Metafurca Y-shaped, basal stalk ca. as long as arms, nearly parallel-sided, bearing high median carina; lateral arms long, narrow, lateral extensions of furcal arm rather large.</p><p>Legs. Procoxa without ventral ridge; ventral surface of anterior femur bearing very coarse and rather shallow punctures (Fig. 24); anterior tibia variable in shape, in some species bisinuate on outer margin (Figs. 39–49). Mesoand metacoxa deeply excised on posterior margin, with dense pubescence developed only basally; ventral surface of meso- and metafemur with sparse semierect setae; meso- and metatibiae widened apically, bearing longitudinal rows of stout spines and some intermixed fine setae on ventral surface, distal margin with a series of stout spines and two long inner spurs; metatarsus shorter than metatibia, bearing dense brushes of thin setae ventrally, metatarsomere 1 ca as long as metatarsomere 2. Claws arcuate.</p><p>Abdomen with five exposed ventrites, ventrite 1 carinate medially, bearing dense and coarse setiferous punctation, lacking sublateral longitudinal ridges (Fig. 25). Punctation on ventrites 2–5 much finer than on ventrite 1.</p><p>Male genitalia. Phallobase as long as parameres or distinctly longer, with or without distinct basal manubrium (Figs. 29–38,a). Median lobe ca. as long as phallobase and parameres combined, not attached to bases of parameres and therefore freely movable within tegmen; gonopore subapical, rather indistinct. Sternite 9 with tongue-like median process of variable shape. Sternite 8 without median projection.</p><p>Female genitalia corresponding to those of the genus Kanala Balfour-Browne 1939 described by Fikáček (2010).</p><p>Recognition. The Asian species of Pachysternum may be easily distinguished from remaining Megasternini genera by the combination of the following characters:</p><p>(1) Pronotum with two sizes of punctures (Figs. 12–14): small ground punctation is intermixed with sparser but much larger and more apparent punctures. [A similar kind of punctation also occurs in Pseudocercyon Orchymont, 1926, Australocyon pilocnemoides group, Cercyon diversipunctus Hebauer, 2002 and some Oriental Cryptopleurum Mulsant, 1844; all of them may be distinguished by the characters below].</p><p>(2) Antennal grooves large, reaching to lateral margin of hypomeron (Fig. 8). [This character distinguish Asian Pachysternum from all taxa mentioned under (1) except of Cryptopleurum]</p><p>(3) Preepisternal elevation of mesothorax triangular, only slightly wider than long (Figs. 15–19). [The shape of the elevation distinguishes Pachysternum from all taxa mentioned under (1). Wide preepisternal plate is also developed in Cryptopleurum in which it is much wider than long and pentagonal rather than triangular, and in Australocyon pilocnemoides group, in which it is bluntly arcuate rather than sharply pointed apically.]</p><p>(4) Median portion of the prosternum elevated into prosternal plate, which is finely but distinctly carinate medially (Figs. 8–11). [There is no prosternal plate in Pseudocercyon and Cercyon, the plate is developed but not carinate medially in Cryptopleurum, in Australocyon pilocnemoides the median portion of prosternum is rather similar to Pachysternum on the first view].</p><p>Taxonomic status. The Asian species of the genus Pachysternum were placed into the formal Pachysternum nigrovittatum group defined by Fikáček (2006), who considered all Asian species as highly similar in the morphology of male genitalia and the presence of the sexual dimorphism in the body shape. The detailed examination of all Asian species revealed that this is valid for all species from the Oriental region, but not for the Palaearctic P. haemorrhoum which differs from the Oriental species in several aspects. The monophyly of the Asian Pachysternum needs therefore to be tested, which was currently impossible for us as the taxonomy of the Afrotropical species assigned to Pachysternum is unsolved. No formal phylogenetic analysis is performed here and we therefore refrain from a redefinition of P. nigrovittatum group in this paper. Below, the characters of possible phylogenetic importance are only briefly discussed.</p><p>1. Phallobase of the aedeagus: (0) with large, asymmetrical and very distinctly detached manubrium; (1) with small basal manubrium or manubrium absent.</p><p>The basal portion of the phallobase is only slightly symmetrical and does not bear any distinctly detached manubrium in all Asian Pachysternum species (Figs. 29, 30–38, a) except P. haemorrhoum, in which the manubrium is large and very distinct (Fig. 31 a). The Afrotropical P. capense Mulsant, 1844 as well as most other taxa of the Megasternum group of genera (i.e. those having large antennal grooves reaching lateral margin of hypomeron, see Hansen (1991) and Fikáček (2008)) bear a very distinct asymmetrical manubrium, which suggests that the character state (1) might be a synapomorphy of all Oriental species of Pachysternum .</p><p>2. Apex of the paramere: (0) with two minute setae; (1) with one long and thick seta, and one very minute one.</p><p>Two apical setae are present on the paramere apex of all Pachysternum examined. In all Asian species except P. haemorrhoum, the apical seta is very long and rather stout (Fig. 28). In P. haemorrhoum, both setae are minute only (Fig. 31 a). Pachysternum haemorhoum shares the character state (0) with P. capense as well as with many other taxa of the Megasternum group of genera (see character 1 for the definition of the group), and the large apical setae might therefore be a synapomorphy of the Oriental Pachysternum species.</p><p>3. Basal part of struts of the median lobe: (0) expanded but not divided into a separate sclerite; (1) hook-like, divided into a separate sclerite.</p><p>Basal part of the struts of the median lobe is divided into a separate sclerite of the hook-like shape in all Oriental Pachysternum (Fig. 27 b), whereas the basal part is only expanded but not divided in P. haemorrhoum (Fig. 26 b). The character state (1) is unique for the Oriental Pachysternum and was not observed in any other taxon of the Megasternini examined so far (basal portion is never divided into a separate sclerite in other Megasternini examined, even though they may be hook-shaped (see, e.g., the median lobe of Cercyon dieganus Régimbart, 1903 in Fikáček (2005)).</p><p>4. Apical portion of the median lobe: (0) at most with very narrow membranous lobes; (1) with large membranous lobes forming a wide rim of the apex.</p><p>Only narrow membranous rim are present in Asian species of Pachysternum (Fig. 27 a) except P. haemorrhoum, in which the membranous parts are wide and the apex of the median lobe is therefore widely rounded (Fig. 26 a). Only small membranous lobes are usually developed in the Megasternini, but this character is highly variable on the species level in some cases (e.g., Fikáček et al. 2009, Fikáček &amp; Hebauer 2009). Relevance of this character is therefore unclear at present.</p><p>5. Lateral portion of the metaventrite (lying laterad of the femoral lines): (0) with moderately coarse punctation and shiny interstices, similar to median portion of the metavetrnite; (1) with coarse punctation and dense pubescence, therefore of different appearance than the median portion of the metaventrite.</p><p>Lateral portions of the metaventrite bears the coarse setiferous sculpture in all Oriental species of Pachysternum (Fig. 20), but fine punctation and shiny interstices in P. haemorrhoum (Fig. 21). The state present in P. haemorrhoum corresponds with the condition found in P. c a pe n s e. However, the appearance is rather variable in various genera of the Megasternum group (see character 1 for the definition of the group) and its relevance is therefore unclear at present.</p><p>6. Deep pits in posterolateral margins of the preepisternal plate of mesothorax: (0) absent; (1) present.</p><p>The appearance of the preepisternal plate of the mesothorax is very uniform in all Asian Pachysternum (Figs. 15–19), but the species differ in the presence/absence of deep pits in its posterolateral corners: pits are missing in all Asian Pachysternum except of those assigned here to the P. apicatum species group (i.e., P. apicatum, P. c ur v a - tum and P. sandacanum; Fig. 18). No pits are developed in the Afrotropical P. capense, and the presence of the pits may therefore be a possible synapomorphy of the P. apicatum species group.</p><p>7. Sexual dimorphism in body shape (males widely rounded, females more elongate with distinctly pronounced shoulder): (0) absent; (1) present.</p><p>Sexual dimorphism in the body shape is not known in any other Megasternine taxa and seems to be unique for the Asian species of Pachysternum; at the same time it seems to be the only character supporting the monophyly of all Asian Pachysternum including P. haemorrhoum . On the other hand, the extent of the difference between the shapes of male and female varies both intra- and interspecifically.</p><p>List of species</p><p>P. apicatum Motschulsky, 1863 China (Hainan), Indonesia (Sumatra, Mentawai Isl., Java, Lombok, Sulawesi), Laos, Malaysia (peninsular part, Sarawak, Sabah), Singapore, Thailand, Vietnam</p><p>P. cardoni d’Orchymont, 1926 Nepal, northeastern India, southern China, Laos, Thailand, Vietnam</p><p>P. coomani d’Orchymont, 1926 India (Manipur), Myanmar, Thailand, Vietnam, Malaysia (peninsular part)</p><p>P. curvatum d’Orchymont, 1925 Philippines (Luzon, Leyte, Mindanao)</p><p>P. haemorrhoum Motschulsky, 1866 Kazakhstan, Mongolia, Russia (Far East, southern Siberia, Sakhalin, Kuril Isl.), northern China, Korea, Japan</p><p>P. kubani sp. nov. northern Laos, China (Sichuan)</p><p>P. nigrovittatum Motschulsky, 1863 Nepal, India, Sri Lanka, southern China, Laos, Singapore, Thailand,</p><p>Vietnam, Malaysia (peninsular part), Indonesia (Sumatra, Sumba) P. rugosum sp. nov.

The characters varying between the species and therefore useful for identification are often quite variable even intraspecifically, which makes the identification rather difficult in many cases. Therefore, diagnostic characters are briefly commented here to make the understanding of their importance and pitfalls easier to the reader.</p><p>General habitus and body coloration. General habitus and the coloration of dorsal side are rather reliable for the identification, but their using usually requires some experience and/or comparison with correctly identified specimens. Shape of the elytra varies to variable extent between male and female of the same species in most taxa, which may be confusing when body shape is used as a diagnostic criterion. Shape of the elytra in females may moreover vary even within a single species, with shoulders being more or less pronounced (the highest variation in this aspect was observed in P. apicatum and P. nigrovittatum). Coloration of dorsal surface is a very useful diagnostic character, but may be extremely variable intraspecifically. The intraspecific variation is described under each species below, and we also tried to cover it by the habitus photographs published within this paper (Figs. 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70).</p><p>Shape of anterior tibia. The shape the anterior tibia is a very useful character (Figs. 39–49). The outer margin of the tibia may be either continually arcuate, or slightly angulate at midlength (the median portion is more or less straight instead of being arcuate in such cases), or bears a distinct but usually shallow emargination (the outer margin is bisinuate in such cases). The shape is invariable in most species except P. apicatum . In addition, the appearance of the series of spines on the outer margin of protibia may be used for the identification – it is either continuous (e.g. in P. cardoni, P. coomani and P. sulawesicum) or interrupted by a wider gap without any spines (e.g. in P. kubani, P. nigrovittatum, P. stevensi). In few species (e.g., P. apicatum), this character is however variable and both continuous and interrupted series of spines may be present in various specimens of the same species. Teratologic malformation of the protibial spines was observed in one specimen of P. kubani (the spines are extremely reduced in this specimen).</p><p>Morphology of male genitalia. Male genitalia (Figs. 29–38) are very uniform in most species, and only those of P. haemorrhoum may be easily distinguished from the remaining species even without any detailed examination. In spite of that, the shape of the median lobe provides useful characters in some cases, with the differences found usually in its general shape and/or the shape of its apical portion. The reliable examination of these characters, however, requires mounting the median lobe separately from the tegmen. The shape of the sternite 9 differs considerably between the species (it may be either entire or bear a more or less deep V-shaped emargination apically). Although the shape is rather constant in most species, a wide variation was observed in P. stevensi (Figs. 34d–e) and P. kubani (Figs. 33f–h), and may possibly concern other species as well (although we did not observe any variation in specimens examined for this study).</p><p>Meso- and metaventrite. The shape of the preepisternal elevation of the mesothorax is very similar in all species treated in this paper, but varies considerably in the presence/absence of slightly depressed areas and/or deep pits in posterolateral corner of the elevation (Figs. 15–19). Reliable examination of this character is, however, very difficult using an usual binocular microscope and it is therefore useless for identification. The appearance of the lateral portions of the metaventrite (Figs. 20–21) provides a good character for distinguishing P. haemorrhoum from all remaining species, but is otherwise uniform in all Oriental species (see under P. haemorrhoum for details).</p><p>Microsculpture of dorsal body surface. The presence/absence of the mesh-like microsculpture was used in the key by Orchymont (1926a). Although it may be helpful in some cases (e.g., P. cardoni usually bears distinct microsculpture, whereas P. kubani usually lacks it), the character is very variable in most species examined (i.e., the microsculpture may be completely absent or very strongly developed in various specimens of the same species). The only exception seems to be P. stevensi in which a strong microsculpture is always present and no variation was observed.</p><p>Identification key</p><p>Because of the scarcity of useful diagnostic characters and their considerable variability within species, the identification may be rather problematic in some cases. We recommend to use the following sequence for the identification: (1) compare your specimen with the photographs of dorsal habitus; (2) check the shape of anterior tibia for the species similar to your specimens by general habitus and coloration; (3) use the following key to confirm the preliminary identification and separate between similarly looking species (the key counts with the intraspecific variability and some species are therefore keyed several times); (4) check carefully the differential diagnosis and variation of the species you decided for in steps 1–3.</p><p>1. Pronotal disc uniformly dark (without pale submedian spots in posterior half), only lateral margins of the pronotum narrowly to widely pale (Figs. 50, 54, 56, 58, 60d–i, 64, 66, 68, 70).

Sumatra. Motschulsky (1863: 448) indicated “le continent indien” as the type locality. This was interpreted as India by all subsequent authors, although Orchymont (1926a) most probably recognized the discordance between this interpretation of the type locality and the distributional area of the species, indicating the distribution as “ Tonkin, Malacca, Iles Mentawei, Java, Iles Lombok (Inde d’après Motschulsky)”. Based on the label data of the types of P. nigrovittatum (see below), Motschulsky used the term “ India ” (or “ India orientalis”) in a very broad sense corresponding with the whole Oriental Region including the islands of Sundaland. This may be also the case of the expression “le continent indien” used in the original description of P. apicatum, even though it seems to refer rather to the continental part of the Oriental Region than to the islands. Taking into account the locality data of type specimens, we specify Sumatra as the type locality of this species and consider the type locality indicated by Motschulsky (1863) as ambiguous.</p><p>Type material. Lectotype (hereby designated): male (ZMUM): “[small yellow triangular label] // Type [small white label, in handwritten] // Pachysternum / apicatum / Motsch / Ind. or. Sumatra [yellow label, in handwritten]”. Paralectotypes: 3 males (ZMUM): same label data as lectotype. [Note: We received four syntypes glued on the same paper label bearing the label mentioned above from ZMUM. One additional specimen, originally glued on the same label according to the remnants of glue, was lost. All four specimens have large hole in the right elytron, indicating that they were pinned originally. The indices of re-mounting of the specimens as well as the discordance of their label data with the type locality given by Motschulsky (1863) impeach the type status of these specimens. However, other indices seem to support their type status: (i) label data, handwriting on the labels and the arrangement of labels corresponds with those attached to the types of Pachysternum nigrovittatum, whose type status is unambiguous; (ii) the specimens correspond with short diagnosis by Motschulsky (1863). For these reasons, we consider all four specimens as syntypes and designate the lectotype from this series. We have remounted each specimen on a separate label, with the lectotype bearing the original labels and paralectotypes bearing their copies.]</p><p>Additional material examined. BRUNEI: 42 spec.

Because of the polymorphism of the dorsal coloration and shape of the anterior tibiae (but not the male genitalia), the correct identification of this species may be rather difficult. Generally, all specimens lacking sharply limited subbasal pale spots of elytra, alternating longitudinal pale and dark stripes on elytra, and/or pale submedian spots at posterior margin of pronotum should be checked for their possible assignment to P. apicatum . Among those, P. haemorrhoum may be easily distinguished by the lateral portions of metaventrite lacking microsculpture on interstices and therefore shiny in appearance (Fig. 21), as well as by its distribution in Palaearctic Region and its completely different male genitalia (Fig. 31). In continental SE Asia and southern and central China, similar species may be distinguished as follows: dark specimens of Pachysternum kubani differ from mainland forms of P. apicatum by the uniformly dark frons (the frons entirely or at least medially pale reddish in mainland P. apicatum) and by the different shape of the apical portion of the median lobe (widely rounded in P. kubani, triangular in P. apicatum; compare Figs. 33c, e and 36c). Pachysternum coomani differs from continental P. ap ic a - tum by more or less entirely pale reddish dorsal body surface (body dark brown to black, with small to large yellow apical elytral spot in continental P. apicatum, Figs. 50 d–g) and by the wide and parallel-sided median lobe of the aedeagus. In the islands of SE Asia, Pachysternum apicatum is very similar to P. curvatum from the Philippines, but is for one thing missing from Philippines, and for another differs in at least very weakly bisinuate or angular outer margin of anterior tibia (Figs. 39 a–b, this character should be checked in other than strict dorsal views as well), by the morphology of the median lobe (Fig. 36), and partly also by the coloration (see P. c u r v a t u m for details). The only species without basal spots on elytra with which P. apicatum co-occurs on the islands of SE Asia is P. sandacanum in northern Borneo; the Bornean form of P. a p i c a t u m (Figs. 50 h–j) may be, however, very easily distinguished from it according to the coloration and shape of anterior tibia (see under P. sandacanum for details).</p><p>Redescription (based on a typical specimen from Lombok Is. corresponding with the lectotype, Figs. 50 a–b). Body widely oval, shape of elytra sexually dimorphic, female with distinctly pronounced humeral portion of elytra. Body length 2.2–3.6 mm (lectotype: 3.1 mm); body width 1.6–2.2 mm (lectotype 2.0 mm).</p><p>Coloration. Head dark brown with pale median portion of frons and clypeus. Pronotum dark brown, with large vaguely limited reddish spot in each anterolateral corner and vague slightly paler spot medially at anterior margin. Elytra black except for pale reddish spot on apex of each elytron extending up to posterior third on intervals 2–6 and along lateral margin. Ventral surface of head and prothorax brown, meso- and metathoracic sclerites black to dark brown; abdominal ventrites 1–4 dark brown with pale lateral portions, ventrite 5 entirely pale. Legs reddish brown, posterior portions of femora darker, brown.</p><p>External morphology. Clypeus with coarse and dense punctation consisting of punctures of two slightly different sizes. Frons with similar but sparser punctation as on clypeus, punctures separated ca. 2–3× puncture diameter. Interstices without microsculpture. Larger punctures on pronotum rounded, much larger than small punctures, small punctures minute, scar-like, divided by 2–3× puncture width. Pronotal interstices without microsculpture. Prosternum with very distinct median carina. Elytral series consisting of large, shallow punctures; interval punctation with minute semicircular punctures much smaller than serial ones, interval punctation consisting of two slightly different sizes of punctures, larger punctures setiferous; interstices without any trace of microsculpture. Elytral series distinctly impressed. Preepisternal elevation of mesothorax with deep posterolateral pits. Femoral lines on metaventrite slightly angulate, median portion of metaventrite bearing moderately large and rather dense setiferous punctation, interstices without microsculpture; lateral portions with very coarse and dense, densely pubescent punctation. Outer margin of anterior tibia very weakly bisinuate, outer series of spines slightly interrupted at the place of the sinuation.</p><p>Male genitalia (Fig. 36). Tegmen 1.5–1.6 mm long, median lobe 1.5 mm long. Phallobase ca. twice as long as parameres, bearing small, slightly asymmetrical basal manubrium. Median lobe widest at midlength, gradually narrowing apicad, apical portion triangular, stump at very apex; gonopore subapical, rather indistinct; lateral pubescent lobes narrow. Sternite 9 with widely rounded median projection, without apical emargination.</p><p>Variation. Extremely variable species, varying especially in coloration and the shape of anterior tibiae, but rather constant in genital morphology. General coloration varies from very dark brown (typical form and majority of mainland forms, Figs. 50 a–f) to pale brown (some mainland forms and the Bornean form, Figs. 50 g–j). Wide variability concerns the color patterns of elytra, the extent of apical elytral pale spot varies from totally absent (Figs. 50 i–j) through very small and confined to very apex only (Figs. 50 d–h, these specimens are very similar to dark specimens of P. kubani sp. nov.) to specimens with large apical spot corresponding with the redescription above (Figs. 50 a–c, this coloration is also present in the lectotype). Very rarely, there is also a vaguely defined pale humeral spot (these specimens resemble P. sulawesicum and may be distinguished by the morphology of male genitalia). Uniformly colored specimens or those with very small and rather indistinct apical elytral spot occur in Borneo and predominate also in the southern part of the Malayan peninsula. On the other hand, specimens from the chain of islands between Sumatra and Lombok and in Sulawesi usually have very distinct and large apical spot, which is also the case of the specimens from northern parts of the continental Asia.</p><p>The shape of anterior tibia varies highly from nearly continually arcuate (in specimens from Java, which are therefore very similar to allied P. c u r v a t u m and P. sandacanum sp. nov.) through weakly angular to indistinctly bisinuate (the most usual form, Fig. 39 a) to deeply emarginate and therefore resembling P. kubani sp. nov. (Fig. 39 b). Deeply excised tibiae occur especially in all examined specimens from Borneo (where P. apicatum is therefore easily recognizable from similar P. sandacanum with continually arcuate outer margin of anterior tibiae) and with higher frequency also in the specimens from continental Asia. In continental specimens we have also found few specimens (from northern Laos and Vietnam) in which the series of spines on outer margin of the tibiae is not interrupted by a gap, as it is usual for the majority of the examined specimens of P. apicatum .</p><p>The wide variability mentioned above makes P. apicatum rather difficult to recognize in many cases. In contrast, the local populations are rather constant in all these characters in most cases (Fig. 72). For example, all specimens from Borneo are rather pale brown, lack the apical elytral spot and have rather deeply bisinuate anterior tibiae; specimens from Malayan peninsula are similar to those from Borneo, but usually much darker; specimens from the island chain from Sumatra to Lombok are most frequently very dark brown, with large and very apparent apical elytral spot and only slightly angular anterior tibiae; and specimens from northern Thailand and northern Vietnam are similar to those from Sumatra in coloration, but have rather deeply bisinuate anterior tibiae. This may suggest that P. apicatum as it is understood here may be in fact a cluster of very similar sibling species. Further studies on wider material and possibly using other than morphological characters would be desirable for complete understanding of the problem which is left unresolved here. The lectotype designated above corresponds with the form with large apical elytral spot and only indistinctly sinuate/angulate outer margin of anterior tibiae, and in the case of splitting into more species, the name P. apicatum had to be therefore applied for that form occurring from Sumatra and adjacent islands through Java to Lombok Is.</p><p>Biology. Based on label data and personal experience, the specimens were collected from various kinds of decaying organic matter, most frequently from decaying plant remains (rotten manihot skins, rotten durian, native vegetable garden refuse, rotting fruit, leaf litter, felled young bamboo shoots), sometimes also collected in baited pitfall traps (with dead fish or dung as the bait) or on carcasses (“dead pig”). No specimen was collected from mammal excrements, which suggests that the biology of P. apicatum probably differs from most other Asian Pachysternum except from P. curvatum and P. sandacanum .</p><p>Distribution. Widely distributed in the whole southeastern Asia, reaching from southern China (Hainan) and northern Thailand, Laos and Vietnam through Malayan peninsula to the islands of Sundaland (Sumatra, Java, Bali Lombok, Sulawesi, Borneo).</p></div>	https://treatment.plazi.org/id/03E687BAFFC2F30BFF5EF9260DDDC5E1	Public Domain	No known copyright restrictions apply.

India, Barway [Mission] [= India, Chhattisgarh state, Jashpur district, Chainpur env., coordinates ca. 23°08'N 84°14'E]. The type locality was erroneously mentioned as “ India, Madhya Pradesh, Barwah” by Hansen (1999). The name Barway, even through missing from recent maps, refers to the name of the Mission led by Belgian Jesuits in the second half of 19th and at the beginning of 20th century, situated around the recent city of Chainpur (see the map by Tete 1984). Tete (1984) also mentions that Farther Cardon was the missionary in charge of the Barway region in 1890’s - this person is evidently the same as “R. P. Cardon” mentioned as a collector of the holotype by Orchymont (1926a).</p><p>Type material examined. Paratypes: 3 spec. (IRSNB): “Gopaldhara / Br. Sikkim / H.

The holotype from “Barway” was not found in the Orchymont collection in IRSNB – it may be lost or was possibly returned to the collection of the Zoological Survey in Kolkata, India which would mean it is inaccessible and possibly damaged. As the original Orchymont’s understanding of this species is clear and not problematic, we refrain from designating the neotype at the moment] .</p><p>Additional material examined.

Pachysternum cardoni is rather easily recognizable by its large and widely oval body, weakly bisinuate outer margin of anterior tibiae, by the pale reddish coloration with large M-shape spot on pronotum (in most specimens) and longitudinal dark stripes along elytral series reaching subapically on series 2–4, and in most cases by rather distinct microsculpture of elytral interstices. However, the species varies rather widely in coloration and dorsal microsculpture, and darker specimens may resemble P. stevensi and P. kubani, which have both also very similar male genitalia. Pachysternum cardoni differs from both these species by clearly developed M-shaped dark spot on the pronotum leaving submedian parts of the pronotum behind midlegth pale (in dark specimens, the M-shape of the dark spot may be indistinct, but the pale submedian areas remain always distinct, Figs. 52e–f). In contrast, no pale submedian spots are developed in most P. kubani and in all P. stevensi; in pale P. kubani, the dark spot is never M-shaped (for additional diagnostic characters, see couplets 3 and 13 in the key above). The pale coloration of the pronotum with the black M-shaped spot of P. cardoni also resembles the coloration of P. nigrovittatum; see couplet 2 in the key above and P. nigrovittatum for diagnostic characters.</p><p>Redescription. Body widely oval, shape of elytra slightly sexually dimorphic, female with distinctly pronounced humeral portion of elytra. Body length 2.9–4.3 mm; body width 2.2–2.8 mm.</p><p>Coloration (Fig. 52). Head dark brown with paler posterolateral corners of clypeus, median portion of frons and yellowish transverse ridge. General coloration of pronotum pale reddish, bearing a wide M-shaped black spot of variable extent, posterolateral corners black. Elytra pale reddish brown, with black stripes of variable extent along elytral series. Ventral surface of head reddish brown, thoracic sclerites dark brown, abdominal ventrites 1–4 largely pale reddish posteriorly, ventrite 5 entirely pale reddish. Legs pale reddish.</p><p>External morphology. Clypeus with moderately coarse but sparse punctation consisting of punctures of two different sizes separated by ca. 1–2× puncture diameter. Punctation of frons similar to that on clypeus. Interstices on head without microsculpture. Larger punctures on pronotum rounded, deeply impressed, much larger than small punctures; small punctures slightly scar-like, divided from each other by 2–3× puncture width. Pronotal interstices without microsculpture. Prosternum with very distinct median carina. Elytral series consisting of large, shallow punctures; interval punctation with rather fine semicircular punctures much smaller than serial ones, with sparsely intermixed slightly larger setiferous punctures of the same shape; interstices without any trace of microsculpture. Elytral series 1 weakly impressed, lateral series distinctly impressed. Preepisternal elevation of mesothorax without posterolateral pits. Femoral lines on metaventrite indistinctly angulate, median portion of metaventrite bearing rather fine and sparse setiferous punctation, interstices without microsculpture; lateral portions with very coarse and dense, densely pubescent punctation. Anterior tibia rather narrow, outer margin slightly bisinuate, outer series of spines not interrupted at the place of the sinuation.</p><p>Male genitalia (Fig. 29). Tegmen 1.6–1.7 mm long, median lobe 1.6–1.7 mm long. Phallobase 2.2× as long as parameres, bearing small, slightly asymmetrical but weakly detached basal manubrium. Median lobe widest at midlength, weakly narrowing apicad, apex narrowly rounded; gonopore subapical, rather indistinct; lateral pubescent lobes indistinct even subapically. Sternite 9 with deep V-shaped apical emargination.</p><p>Variation. Variable in the extent of the black spots on pronotum and especially elytra. Pronotal M-shaped spot may be slightly more or less expanded, but in all cases retains its M-like shape and leaves large submedian areas on the pronotum pale reddish. Elytral dark stripe along the punctate series vary from largely expanded and therefore completely or partly merging the adjacent stripes, to slightly darkening of elytral series not expanding to intervals at all and leaving the elytra nearly uniformly reddish. Microsculpture of elytra varies from totally absent even laterally to very clearly developed mesh-like microsculpture on lateral portion of the elytron.</p><p>Biology. Unknown.</p><p>Distribution. Widely distributed through NE India and Nepal, central and southern China and northern part of SE Asia. Recorded for the first time for Thailand and Vietnam. The unspecified records from the Chinese provinces Guizhou and Yunnan mentioned by Hansen (2004) were based on the above specimens from these regions.</p></div>	https://treatment.plazi.org/id/03E687BAFFDFF30CFF5EFDDD0942C3B3	Public Domain	No known copyright restrictions apply.

INDIA: Manipur: Imphal district, Ucharthal, 5 km E of Jiribam (Mukhopadhyay &amp; Sengupta 2004).</p><p>Differential diagnosis. Rather easily distinguishable from all remaining species occurring in continental SE Asia by its pale reddish general coloration (Fig. 54), small body size and continually arcuate outer margin of anterior tibiae (Fig. 43); the very wide and nearly parallel-sided median lobe of the aedeagus (Fig. 30) is also very characteristic and cannot be confused with any other species. Darker specimens with stronger interstitial microsculpture on elytra may resemble P. stevensi, but can be easily distinguished from it by continually arcuate outer margin of anterior tibiae (distinctly sinuate in P. stevensi) and wide, nearly parallel-sided median lobe. By general coloration, Pachysternum coomani also slightly resembles Bornean specimens of P. a p i c a t u m, from whose it also differs by continually arcuate outer margin of anterior tibiae (rather deeply sinuate in Bornean P. apicatum).</p><p>Description. Body widely oval, shape of elytra not sexually dimorphic, female without distinctly pronounced humeral portion of elytra. Body length 2.2–2.9 mm (holotype: 2.4 mm); body width 1.5–1.8 mm (holotype 1.6 mm).</p><p>Coloration (Fig. 54). Whole dorsal surface more or less uniformly reddish brown, with slightly darker lateral portions of frons, posterolateral portions of pronotum, base of elytra and elytra at midlength. Ventral surface of head reddish brown, thoracic sclerites brown, abdominal ventrites reddish brown, legs pale reddish.</p><p>External morphology. Clypeus with moderately coarse but sparse punctation consisting of uniformly-sized rasp-like punctures separated from each other by ca. 1–3× puncture diameter. Punctation of frons similar to that on clypeus. Interstices on head without microsculpture. Larger punctures on pronotum rounded, shallow, much larger than small punctures; small punctures scar-like, divided from each other by ca. 3× puncture width. Pronotal interstices without microsculpture. Prosternum with very distinct median carina. Elytral series consisting of large, shallow punctures; interval punctation with rather fine semicircular punctures much smaller than serial ones, with sparsely intermixed setiferous punctures of the same shape and size; interstices with weak mesh-like microsculpture. Elytral series 1 not impressed, lateral series only very weakly impressed. Preepisternal elevation of mesothorax without posterolateral pits. Femoral lines on metaventrite indistinctly angulate, median portion of metaventrite bearing rather fine, moderately dense setiferous punctation, interstices without microsculpture medially, with weak microsculpture consisting of partially joint ridges laterally; lateral portions with very coarse and dense, densely pubescent punctation. Anterior tibia rather wide, outer margin continually arcuate, outer series of spines not interrupted.</p><p>Male genitalia (Fig. 30). Tegmen 1.0– 1.1 mm long, median lobe 1.0– 1.1 mm long. Phallobase 2.5× as long as parameres, bearing small, slightly asymmetrical, distinctly detached basal manubrium. Median lobe rather wide, nearly parallel-sided at midlength, strongly narrowing apicad, apex widely rounded; gonopore subapical, rather indistinct; lateral pubescent lobes narrowly developed subapically. Sternite 9 with moderately large V-shaped apical emargination.</p><p>Variation. Dorsal coloration varies slightly in the extent of the darker areas on the head, pronotum and elytra: type specimens are paler (uniformly reddish) than some specimens from Malaysia, in which some parts of the elytra are distinctly darker, brown (Fig. 54d). Microsculpture of elytral interstices varies from weakly developed to very distinct.</p><p>Biology. The specimens from Malaysia were collected in cow excrements; most probably a coprophilous species.</p><p>Distribution. Based on the examined specimens, the species seems to be widely distributed in the mainland SE Asia, reaching from northeastern India (Manipur state) to southern Vietnam and Malayan peninsula, but the specimens are rather rare in collections. The species is recorded here for the first time from Malaysia, Myanmar and Thailand.</p></div>	https://treatment.plazi.org/id/03E687BAFFDAF300FF5EFF4C0D36C538	Public Domain	No known copyright restrictions apply.

Philippines, Luzon island, Imugan.</p><p>Type material examined. Lectotype (here designated): 1 male (IRSNB): “ Imugan, Luzon // Cotype // Pachysternum / curvatum // coll. d’Orchymont // Para- / type” [considered as a paratype by Orchymont (1926b)]. Paralectotypes: 1female (IRSNB): same locality data as the lectotype [considered as the holotype by Orchymont (1926b)]; 1 female 1 male (IRSNB): “ Mt. Banahao / Luzon // Cotype // Pachysternum / curvatum // coll. d’Orchymont // Para- / type ”. The species was described twice: (1) a short Latin description lacking any data on type specimens was published by Orchymont (1925); (2) a detailed English description with precise citing of type specimens was published by Orchymont (1926b). The description published by Orchymont (1925) fulfills all requirements of the International Code of Zoological Nomenclature (ICZN 1999) and the paper is therefore correctly considered as the original description (see, e.g., Hansen 1999). However, the type material is not specified in this paper and no holotype is designated; all type specimens used for the description has to be therefore formally considered as syntypes. The subsequent designation of the holotype by Orchymont (1926b) is therefore invalid following Articles 73.1.3. and 72.4.1 of the Code (ICZN 1999). Hence, the lectotype of the species is designated herein: as the differences in male genitalia are crucial for the diagnosis of the species, we have chosen the single male available as the lectotype, irrespectively to the previous decision by Orchymont (1926b) to designate the female from Imugan as “the holotype ”.</p><p>Additional material examined: PHILIPPINES: Leyte: 1 spec.

By the general coloration and continually arcuate outer margin of anterior tibiae rather easily distinguishable from all Pachysternum species except the some forms of P. apicatum, P. sandacanum from northern Borneo and P. haemorrhoum from eastern Palaearctic. Except for the fact that P. curvatum is the only species of the genus in Philippines and does not co-occur with any above species (as well as with any other species of Pachysternum), it may be distinguished from them by the shape of the median lobe of the male genitalia (gradually narrowing apicad and acute at the very apex (Fig. 37b–c), in contrast to blunt at very apex in P. apicatum, distinctly narrowed in apical fourth in P. sandacanum and widely expanded subapically in P. haemorrhoum). Pachysternum sandacanum also differs by smaller body size (2.6–3.3 mm in P. curvatum, 2.3–3.1 mm in P. sandacanum). Most specimens of P. apicatum may be distinguished by at least weakly sinuate or angulate outer margin of anterior tibiae (at least when seen in slightly different angles than dorsally; outer margin of anterior tibiae is continually arcuate in P. curvatum even when seen from slightly oblique angles). Pachysternum haemorrhoum also differs by the uniform microsculpture throughout the metaventrite (Fig. 21), in contrast to the highly microsculptured and densely pubescent metaventrite laterally of the femoral lines in P. curvatum (as in Fig. 20)</p><p>Redescription. Body widely oval, shape of elytra sexually dimorphic, female with distinctly pronounced humeral portion of elytra. Body length 2.1–3.3 mm (lectotype: 2.3 mm); body width 1.6–2.2 mm (lectotype 1.7 mm).</p><p>Coloration (Fig. 56). Clypeus reddish to dark brown, frons uniformly dark brown without apparently pale median portion. Pronotum dark brown, lateral margins only very vaguely and narrowly paler. Elytra brown to dark brown, except for pale reddish spot on apex of each elytron extending up to posterior fourth to third on intervals 2– 5. Ventral surface brown to dark brown, abdominal ventrites 1–4 brown with pale lateral portions, ventrite 5 entirely pale. Legs reddish brown.</p><p>External morphology. Clypeus with coarse and dense punctation consisting of uniform punctures. Frons with punctations similar to that on clypeus, punctures separated ca. 2–3× puncture diameter. Interstices without microsculpture. Larger punctures on pronotum rounded, much larger than small punctures, small punctures minute, scar-like, divided by 2–3× puncture width. Pronotal interstices without microsculpture. Prosternum with very distinct median carina. Elytral series consisting of large, shallow punctures; interval punctation with minute semicircular punctures much smaller than serial ones, interval punctation consisting of two slightly different sizes of punctures, larger punctures setiferous; interstices without any trace of microsculpture. Elytral series distinctly impressed. Preepisternal elevation of mesothorax with deep posterolateral pits. Femoral lines on metaventrite slightly angulate, median portion of metaventrite bearing moderately coarse but rather sparse setiferous punctation, interstices without microsculpture; lateral portions with very coarse and dense, densely pubescent punctation. Outer margin of anterior tibia continually arcuate, outer series of spines not interrupted.</p><p>Male genitalia (Fig. 37). Tegmen 1.1–1.2 mm long, median lobe 1.2–1.3 mm long. Phallobase ca. twice as long as parameres, bearing small, slightly asymmetrical basal manubrium. Median lobe widest at midlength, gradually narrowing apicad, apical portion triangular, acute at very apex; gonopore subapical, rather indistinct; lateral pubescent lobes narrow. Sternite 9 with widely rounded median projection, without apical emargination.</p><p>Variation. Slight variability was observed only in the extent of pale spots on elytra (Fig. 56) and in the coloration of the clypeus, which may be pale reddish to dark brown.</p><p>Biology. A long series of this species has been collected from “rotting figs” at Mt. Makiling by L. Watrous. Collecting circumstances of other specimens are unknown.</p><p>Distribution. Endemic to Philippines, known from islands of Luzon, Leyte and Mindanao.</p><p>Discussion. The species is rather similar to the some specimens of P. apicatum in all external characters including the presence of deep pits in posterolateral corners of the preepisternal elevation of the mesothorax (as in Fig. 18). Based on its vicariant distribution with P. apicatum, it may in fact even represent only a local population or subspecies of P. apicatum . However, the small differences in the shape of the apex of the median lobe of the aedagus and in the shape of the anterior tibiae support the status of P. curvatum as a separate species. Pachysternum curvatum is also very similar to P. sandacanum from northern Borneo in dorsal coloration and shape of anterior tibiae, but the differences in body size and in the shape of the median lobe between these species is very apparent and clearly supports the separate specific status of the populations in Philippines and in northern Borneo.</p></div>	https://treatment.plazi.org/id/03E687BAFFD4F302FF5EFEB90907C1EA	Public Domain	No known copyright restrictions apply.

Megasternum gibbulum: Japan. Megasternum distinctum: Japan. Pachysternum sibiricum: Russia, Vladivostok.</p><p>Type material. Pachysternum haemorrhoum: Lectotype (hereby designated): 1 spec. (ZMUM): “ Pachysternum / haemorrhoum / Motsch. / Japonia [yellow label, in handwritten]” Paralectotype: 1 spec. (ZMUM): same label data as the lectotype, with additional lectotype label “Lectotypus / Pachysternum haemorrhoum / Motsch. / design. Shatrovskiy 1986” . There are two specimens of P. haemorrhoum in the Motschulsky collection, both corresponding with the original description in the locality data and the characters mentioned (including of the coloration). In contrast to type specimens of P. nigrovittatum and P. apicatum, the specimens do not bear the original indication of the type status. In accordance with A. G. Shatrovkiy who designated one of these specimens as lectotype, and with Hansen (1998), we consider them as a part of the original type series. The lectotype designation by Shatrovskiy was never published and is therefore invalid according to International Code of Zoological Nomenclature (ICZN 1999). As the specimen bearing Shatrovskiy’s lectotype label is totally disarticulated, we designate here the second, complete specimen as the lectotype.</p><p>Megasternum gibbulum: Lectotype (hereby designated): 1 male (ZMUM): “ Megasternum / gibbulum / Motsch. / Japonia [yellow label, handwritten] // Lectotypus 3 / Megasternum / gibbulum / Motsch . / design. Shatrovskiy 1985 // Pachysternum / haemorrhoum Motsch . / det. Shatrovskiy 1986”. The lectotype designation was never published and is therefore invalid according to International Code of Zoological Nomenclature (ICZN 1999). Hence, the single available specimen is formally designated as lectotype here.</p><p>Megasternum distinctum: Lectotype (hereby designated): 1 spec. (BMNH): “Lecto- / type [round label with violet margin] // Type [round label with red margin] // Japan [printed label with yellow stripe] // Sharp Coll / 1905– 131 // Japan [round yellow label, handwritten] // Megasternum / distinctum / Type D. S. [in handwritten] // Lectotypus Ƥ / Megasternum / distinctum Sharp / design. Shatrovskiy 1984 [red label, partly handwritten]” . The species was described according to two specimens (Sharp 1873). Only one of these specimens is deposited in BMNH, bearing the lectotype label by A. Shatrovskiy. However, the lectotype designation was never published and is therefore invalid according to International Code of Zoological Nomenclature (ICZN 1999). Hence, the specimen is formally designated as lectotype here.</p><p>Pachysternum sibiricum: Lectotype (hereby designated): 1 spec. (HNHM): “ Siberia or. / Wladiwostock [printed] // coll. Reitter [printed] // Holotype 1890 / Pachysternum / sibiricum / Kuwert [white label with red border]”. On our request we have received the only specimen labeled as holotype from HNHM. However, the holotype label corresponds with those attached routinely to the type specimens in this museum and its handwriting does not correspond with Kuwert’s handwriting. Number of type specimens is not indicated in the original description, therefore we must consider the single available specimen as a part of type series. For this reason, we hereby designate this specimen as the lectotype.</p><p>Additional material examined. CHINA: Heilongjiang: 1 spec.

(Shatrovskiy 1989). “ KOREA ”: unspecified record from “Korean Peninsula” (Shatrovskiy 1989).</p><p>Differential diagnosis. Pachysternum haemorrhoum is characteristic by continually arcuate outer margin of anterior tibiae (Fig. 44), rather large body size and uniformly dark coloration with elytra becoming largely pale reddish apically (Fig. 58). By these characters it may be distinguished from all remaining species of Asian Pachysternum except the species of the P. apicatum complex ( P. apicatum, P. c u r v a t u m and P. sandacanum). However, it differs from all species including those of the P. apicatum complex by the lateral portions of the metaventrite being of the same appearance as the median portion (i.e. shiny and without pubescence (Fig. 21); in all remaining species the lateral portions bear coarse sculpture and dense pubescence) and by the morphology of its male genitalia (especially by large and very distinctly detached manubrium of the basal piece and by widely rounded apex of the median lobe (Fig. 31)). The species is also the only eastern Palaearctic species of Pachysternum and does not cooccur with any other Asian species of the genus.</p><p>Redescription. Body widely oval, shape of elytra sexually dimorphic, female with slightly pronounced humeral portion of elytra. Body length 2.6–3.5 mm (lectotype: 2.9 mm); body width 1.9–2.3 mm (lectotype 2.0 mm).</p><p>Coloration (Fig. 58). Head black, only with dark reddish narrow transverse ridge. Pronotum black, with vaguely defined dark reddish spot in anterolateral corners. Elytra black to dark brown basally, elytral interval 1 dark throughout, remaining portions of elytra becoming gradually paler towards brown to reddish brown apex. Ventral surface of head and thoracic sclerites black to dark brown, abdominal ventrites 2–5 largely reddish brown, legs pale reddish with darker basal portions of femora.</p><p>External morphology. Clypeus with coarse and rather dense punctation consisting of uniformly-sized rounded punctures separated from each other by ca. by puncture diameter. Punctation of frons similar to that on clypeus but slightly sparser, punctures separated by ca. 1–2× puncture diameters and becoming slightly transverse at least laterally. Interstices on head without microsculpture. Larger punctures on pronotum rounded, moderately impressed, slightly larger than small punctures; small punctures fine, slightly transverse, rather deeply impressed, divided from each other by ca. 2–3× puncture diameter. Pronotal interstices without microsculpture. Prosternum with very distinct median carina. Elytral series consisting of large, shallow punctures; interval punctation with rather fine semicircular punctures much smaller than serial ones, with sparsely intermixed slightly larger setiferous punctures of the same shape; interstices without microsculpture. Elytral series 1–7 not impressed, series 8–10 only very weakly impressed. Preepisternal elevation of mesothorax without posterolateral pits. Femoral lines on metaventrite continually arcuate, median portion of metaventrite bearing rather dense and coarse setiferous punctation, interstices without microsculpture; punctation of lateral portions similar to that of median portion, lacking dense pubescence. Anterior tibia rather wide, outer margin continually arcuate, outer series of spines only indistinctly interrupted.</p><p>Male genitalia (Fig. 31). Tegmen 1.1 mm long, median lobe 1.1 mm long. Phallobase 1.5× as long as parameres, bearing large asymmetrical, very distinctly detached basal manubrium. Median lobe rather wide, nearly parallel-sided throughout except apically, abruptly triangularly narrowing apically; gonopore subapical, rather indistinct; lateral pubescent lobes wide, forming a rounded rim of apical portion of the lobe. Sternite 9 very narrow, without V-shaped apical emargination.</p><p>Variation. The species varies slightly in the coloration of elytra and in structures of the metaventrite. The elytra of paler specimens may be nearly uniformly dark reddish brown, without the black bases (Fig. 58c). Interstices of the metaventrite may bear shallow but rather distinct mesh-like microsculpture laterally (some specimens from Irkutsk province: Shelekhov). Femoral lines may be more or less elevated anteriorly, and relatively more or less distinct posteriorly; variation in this character is rather narrow and is not influenced geographically. Specimens with variable development of the femoral lines, with presence/absence of microsculpture on the metaventrite, as well as with described variations of elytral coloration agree with “typical” specimens in all other external characters including of the shape of anterior tibia and the male genitalia, and the variation is therefore considered as intraspecific.</p><p>Discussion. The strength of the femoral lines was used as diagnostic character distinguishing the Japanese P. haemorrhoum from the mainland P. sibiricum . The variation of this character is very low, is not affected by the geography and the character vary even in the specimens from a single locality. We therefore consider P. sibiricum as a synonym to P. haemorrhoum . This also agrees with the opinion by Shatrovskiy (1989) and Hebauer &amp; Ryndevich (2005) who published the mainland specimens under the name P. haemorrhoum and refrained from distinguishing P. sibiricum as a distinct taxon (F. Hebauer, pers. comm.).</p><p>Distribution. Widely distributed from the eastern Kazakhstan and western Siberia through southern parts of eastern Siberian and Russian Far East, northern China and Korean peninsula to Japan. The record from the Philippines by Shatrovskiy (1989) is very probably based on misidentified specimens of P. c u r v a t u m and is not considered here.</p></div>	https://treatment.plazi.org/id/03E687BAFFD6F306FF5EF9CF0D01C240	Public Domain	No known copyright restrictions apply.

A. Pütz ”.</p><p>Differential diagnosis. Pale specimens of Pachysternum kubani sp. nov. (Figs. 60a–f) are easily recognizable from other Pachysternum species by pale yellowish elytra with irregularly lobate transverse dark stripe in anterior third (Figs. 60a–e) or by very distinct pale humeral spots (Fig. 60f), and distinctly bisinuate outer margin of anterior tibiae. By the coloration, these specimens may be confused with P. stevensi, from which they differ by the characters given in couplet 12 of the identification key. The body form of large specimens (and also the presence of pale spots on pronotal disc in pale specimens) resembles P. cardoni; in contrast to it, the dark coloration of elytral series 2–4 reaches at most the midlength in pale specimens of P. kubani (it reaches subapically in P cardoni), both species differ in the color pattern of the pronotum (with dark M-shaped spot or at least distinct pair of pale spots submedially in P. cardoni, with anteriorly trilobate dark spot or completely dark pronotal disc in P. kubani) and the elytral microsculpture is also frequently different (absent in P. kubani, distinctly developed or rarely missing in P. c a rdoni). Dark specimens, which are usually slightly smaller than paler ones, highly resemble the mainland forms of P. apicatum (with which they sometimes even co-occur) in the coloration and very often also in the shape of anterior tibia; they may be distinguished from P. apicatum by the characters given in the couplet 15 of the identification key.</p><p>Description (based on the holotype). Body widely oval, shape of elytra slightly sexually dimorphic, female with distinctly pronounced humeral portion of elytra. Body length 2.2–3.5 mm (holotype: 3.3 mm); body width 1.6–2.2 mm (holotype 2.2 mm).</p><p>Coloration (Fig. 60). Clypeus and lateral portions of frons black, transverse ridge between eyes and large median portion of the head pale reddish. Pronotum widely pale reddish along lateral and anterior margins, bearing large posteriorly wide and anteriorly trilobate black spot. General coloration of elytral yellowish; interval 1 black throughout, all elytral series black in anterior half, the black coloration slightly extending to intervals from series 2–5, but largely extending across intervals 6–11, forming large lateral black spot in anterior third of elytra. Ventral surface of head brown, mentum and thoracic sclerites black, abdominal ventrites dark brown anteriorly, largely pale reddish posteriorly. Legs brown, femora black.</p><p>External morphology. Clypeus with moderately coarse but rather sparse punctation consisting of rounded punctures of two slightly different sizes. Punctation of frons similar to that on clypeus, with punctures separated by 2–4× the puncture diameter. Interstices on head without microsculpture. Larger punctures on pronotum slightly crescent-like, deep, much larger than small punctures; small punctures slightly semicircular, divided from each other by ca. 1–1.5× puncture width. Pronotal interstices without microsculpture. Prosternum with very distinct median carina. Elytral series consisting of large, shallow punctures; interval punctation with rather fine semicircular punctures much smaller than serial ones, with sparsely intermixed slightly larger setiferous punctures of the same shape; interstices without microsculpture. Elytral series weakly impressed. Preepisternal elevation of mesothorax without posterolateral pits. Femoral lines on metaventrite indistinctly angulate, median portion of metaventrite bearing moderately coarse and dense punctation, interstices without microsculpture; lateral portions with very coarse and dense, densely pubescent punctation. Anterior tibia rather wide, outer margin distinctly bisinuate, outer series of spines interrupted at the place of emargination.</p><p>Male genitalia (Fig. 33). Tegmen 1.3–1.5 mm long, median lobe 1.3–1.5 mm long. Phallobase 2× as long as parameres, bearing small, slightly asymmetrical, indistinctly detached basal manubrium. Median lobe rather narrow, widest in basal third, weakly narrowing apicad, apex narrowly rounded; gonopore subapical, rather indistinct; lateral pubescent lobes indistinct even subapically. Sternite 9 entire, rather narrow.</p><p>Variation. The species varies considerably in the extent of the black coloration on the head, pronotum and elytra. Coloration of the frons may vary from entirely dark brown to wide pale spot situated medially. Pronotum may bear large black spot which is wide posteriorly, but trilobate anteriorly, or may be completely black on the disc, with widely pale lateral margins (the pale areas widest anteriorly and narrowest posteriorly in that case) and median portion of anterior margin. Elytral coloration varies from largely reddish with irregular dark spots at anterior third of the elytral series (Fig. 60c) through reddish with a more or less extended irregularly shaped transverse dark stripe at anterior third (Figs. 60a–b, d–e) to largely dark brown to black with large to very small apical reddish spot and in some cases also basal pale spots (Figs. 60f–i). The shape of the male sternite 9 varies from rounded (in the holotype and majority of the specimens examined; Fig. 33f) to shallowly emarginate (rarely found at the same localities where specimens with rounded apex of the sternite 9 predominate, Fig. 33g); a very deeply emarginate sternite 9 was found in a male from Xiangkhouang (Fig. 33h) which also has extremely shortened tibial spines (all remaining specimens from the locality have usually developed sternite 9 as well as tibial spines, and the specimen is therefore considered as teratological here). This variation of the shape of the sternite 9 resembles that observed in P. stevensi, in which both rounded and emarginate forms are more frequent, however.</p><p>Etymology. The species is dedicated to my colleague Vítĕzslav Kubáň (NMPC) who collected most type specimens of this species.</p><p>Biology. Unknown. Most specimens were collected in primary or secondary mountain forests using flight intercept traps.</p><p>Distribution. Known from four localities in northern Laos (provinces Bolikhamsai, Houaphan, Phongsali and Xiangkhouang) and from central China (Sichuan).</p></div>	https://treatment.plazi.org/id/03E687BAFFD2F339FF5EF96C0ECDC6E3	Public Domain	No known copyright restrictions apply.

Sri Lanka, a mountain in the environs of Nuwara Eliya (“Montagne de Nura-Ellia”).</p><p>Type material. Lectotype (hereby designated): 1 female (ZMUM): “[tiny red piece of paper] // [small rounded yellow label] // Type [small white label, in handwritten] // Pachysternum / nigrovittatum / Motsch. / Ind. or. Ceyl . M t. N. [yellow label, in handwritten]”. Paralectotype: 1 spec. [only head, prothorax and a mesothoracic leg preserved] (ZMUM): same label data as lectotype . On our request we have received two above mentioned specimens from the Motschulsky collection in ZMUM; both were glued on the same paper label. There is no indication of the number of syntypes in the original description, but the given type locality (“Montagne de Nura-Ellia et sur le continent indien”) indicates that Motschulsky (1863) examined also the specimens from other localities than Sri Lanka when describing the species. Therefore, some syntypes seem to be missing in his collection. In the present paper we are designating the complete specimen mentioned above as the lectotype, the remaining incomplete specimens as well as the remaining specimens not available to us have to be considered as paralectotypes.</p><p>Additional material examined.

INDIA: Andhra Pradesh: Kurnool district, Betamcherla; Prakasan district, Matur [= Martur] (both Mukhopadhyay 2007). Manipur: Andro, Imphal (Mukhopadhyay &amp; Sengupta 2004). Sikkim: Mongan (Mukhopadhyay &amp; Sengupta 2003). West Bengal: without detailed localities (Mukhopadhyay 2007). LAOS: Loung Namtha: Louang Namtha env. (Hebauer &amp; Ryndevich 2005). THAILAND: Chiang Mai: Chiang Mai (Hebauer &amp; Ryndevich 2005).</p><p>Diagnosis. The species may be very easily distinguished from all remaining Asian Pachysternum by the combination of pale pronotum with large M-shape spot, elytra pale with at least some of elytral intervals 2–10 completely dark (Fig. 62), and deeply bisinuate outer margin of anterior tibia (Fig. 46). By the coloration of pronotum it resembles P. cardoni which is much larger and wider and never bears the combination of entirely pale elytral interval 2 and largely dark interval 4, and the apical portion of its median lobe is gradually narrowing apicad (narrow and nearly parallel-sided in P. nigrovittatum, Fig. 32 b). The elytral coloration of P. nigrovittatum may resemble pale specimens of P. sulawesicum, but may be easily distinguished from it by deeply bisinuate outer margin of anterior tibiae (continually arcuate in P. sulawesicum) and distinctly narrowed apical portion of the median lobe (nearly parallel-sided throughout in P. sulawesicum).</p><p>Redescription (based on specimens from Sri Lanka). Body elongate oval, shape of elytra sexually dimorphic, female with very distinctly pronounced humeral portion of elytra. Body length 2.2–3.0 mm (lectotype: 2.3 mm); body width 1.4–2.0 mm (lectotype 1.6 mm).</p><p>Coloration (Fig. 62). Head brown widely pale reddish median portion of frons and transverse ridge. General coloration of pronotum pale reddish, bearing M-shaped black spot of variable extent, leaving wide lateral portions, anteromedian part and a pair of large posterior submedian parts reddish; posterior margin black. Elytra pale reddish brown, with alternating pale and black intervals as follows: interval 1 entirely black, interval 2 entirely pale, interval 3 pale except of short black portion in anterior third, interval 4 black in anterior four fifths, pale apically, interval 5 entirely pale, interval 6 similar to 4, but with short pale area subbasally, intervals 7–9 pale subbasally (forming pale humeral spot), otherwise black except for apical-most portion, Interval 10 (lateralmost one) pale. Ventral surface of head and prothorax reddish brown, meso- and metathorax dark brown, abdominal ventrites 1–4 largely pale reddish posteriorly, ventrite 5 entirely pale reddish. Legs pale reddish.</p><p>External morphology. Clypeus with fine and rather sparse punctation consisting of slightly semicircular punctures of two slightly different sizes separated by ca. 1–2× puncture width. Punctation of frons similar to that on clypeus, only with slightly larger punctures. Interstices on head without microsculpture. Larger punctures on pronotum semicircular, deeply impressed, much larger than small punctures; small punctures transverse, divided from each other by 2–3× puncture width. Pronotal interstices without microsculpture. Prosternum with distinct median carina. Elytral series consisting of large, shallow punctures; interval punctation with very fine semicircular punctures much smaller than serial ones, with sparsely intermixed slightly larger setiferous punctures of the same shape; interstices with weakly developed mesh-like microsculpture. Elytral series weakly impressed. Preepisternal elevation of mesothorax without posterolateral pits. Femoral lines on metaventrite indistinctly angulate, median portion of metaventrite bearing moderately coarse and dense setiferous punctation, interstices without microsculpture; lateral portions with very coarse and dense, densely pubescent punctation. Anterior tibia rather narrow, outer margin deeply bisinuate, outer series of spines interrupted at the place of the sinuation.</p><p>Male genitalia (Fig. 32). Tegmen 1.3–1.4 mm long, median lobe 1.3–1.4 mm long. Phallobase ca. 2× as long as parameres, basally slightly asymmetrical but without detached manubrium. Median lobe widest in basal third, weakly narrowing to apical third, narrow and nearly parallel-sided in apical third, apex rounded; gonopore subapical, rather indistinct; lateral pubescent lobes distinct only subapically. Sternite 9 narrow, without V-shaped apical emargination.</p><p>Variation. Rather variable species, with the variation concerning mainly the coloration, dorsal microsculpture, body size and slightly also the extent of sexual dimorphism in body shape. Pale specimens (Fig. 62c) have largely reddish elytra with dark T-shape spot (consisting of dark elytral interval 1 and bark base of elytra) and dark spots at midlength of intervals 4 and 6–9 and subbasally on intervals 6–7. The extent of dark area is increasing in other specimens through the most typical coloration mentioned in the redescription (Figs. 62a–b), to dark specimens with largely black elytra and very apparent reddish spots at bases and in apical portions of intervals 2, 3, 5 and 8– 10 and narrowly pale lateral margin of elytron (Fig. 62g). The coloration of pronotum varies in the same extent, bearing a median and a pair of submedian dark spots in palest specimens (Fig. 62c), the dark M-shaped spot in most specimens (Figs. 62a–b, d–e) and a being largely dark at pronotal disc with only a weakly developed pale spots submedially in dark specimens (Figs. 62f–g). Dorsal microsculpture usually consists of rather weak meshlike microsculpture which is often rather inconspicuous, but in extremely dark and/or small specimens the microsculpture is often very distinct. The body shape of males is constant in all specimens examined, but the shape of females may vary from rather short and wide specimens with weakly pronounced shoulders to very distinctly elongate specimens with highly pronounced shoulders and elytra strongly narrowing apicad (the most elongate females are known from the island of Sumba). The shape of the anterior tibia as well as of the male genitalia (including the median lobe and sternite 9) is very constant in all examined specimens irrespectively to their variation in the above characters, which we therefore consider as intraspecific.</p><p>Biology. Coprophagous species inhabiting excrements of various herbivorous mammals.</p><p>Distribution. Widespread throughout the Oriental Region from Nepal and Sri Lanka through India, whole continental SE Asia and some of the islands of Sundaland (Sumatra, Sumba). Records are surprisingly missing for whole lowland northern part of India (and P. nigrovittatum seems therefore be absent from semidesert areas) and from many islands of Sundaland (in this case most probably because of the collecting bias).</p></div>	https://treatment.plazi.org/id/03E687BAFFEDF33DFF5EFCC9089EC5EB	Public Domain	No known copyright restrictions apply.

It may resemble dark specimens of P. stevensi, which, however, differ by sinuate outer margin of the anterior tibia. By the large and wide body it resembles P. cardoni, which differs in the presence of pale spots on pronotum and elytra, slightly sinuate outer margin of anterior tibiae, and much finer punctation of pronotum and elytra.</p><p>Description. Body widely oval, female without pronounced humeral portion of elytra (males unknown, but sexual dimorphism in body shape probably absent).

Malaysia, Borneo, Sabah state, 8 km S Gunung Trus Madi, 549 m a.s.l., [coordinates ca. 5°28'29''N, 116°31'6''E].</p><p>Type material. Holotype: male (BMNH): “SABAH: 5 m. S. / Mt.

Based on the general appearance and coloration in combination with continually arcuate outer margin of anterior tibiae, P. sandacanum is very similar to P. curvatum, P. coomani and typically colored specimens of P. apicatum . From P. coomani, it may be distinguished according to the shape of the median lobe (wide and nearly parallel-sided throughout in P. coomani (Fig. 30), distinctly narrowed into narrow apical fourth in P. sandacanum (Fig. 38)), clearly defined yellowish apical spot on elytra (the elytra are gradually getting paler posteriad in P. coomani, Fig. 54) and in much finer punctation of elytral intervals (punctation is rather coarse and dense in P. coomani). Distinguishing of P. sandacanum from P. curvatum and the polymorphic P. apicatum may be rather difficult, but is clearly possible on the basis of the morphology of the median lobe of the aedeagus (distinctly narrowed in apical fourth in P. sandacanum, gradually narrowing apicad in P. curvatum and P. a p i c a t u m) and partly also on the basis of the body size (specimens of P. sandacanum are usually distinctly smaller than those of P. apicatum and P. curvatum). However, the identification of P. sandacanum is easy when the distributional data are taken into account: the species co-occurs only with P. apicatum on the island of Borneo and may be easily distinguished from the Bornean form of P. apicatum according to the elytra coloration (with large yellow spot at apex in P. sandacanum, entirely reddish brown to brown in Bornean P. apicatum (Figs. 50 h–j)) and according to the shape of the anterior tibia (continually arcuate on outer margin in P. sandacanum (Fig. 41), but distinctly bisinuate in Bornean P. apicatum (Fig. 39 b)). Pachysternum sandacanum does not co-occur with P. coomani and P. curvatum, which are absent from the island of Borneo.</p><p>Description. Body oval, shape of elytra slightly sexually dimorphic, female with indistinctly pronounced humeral portion of elytra. Body length 2.3–3.1 mm (holotype: 2.6 mm); body width 1.6–2.0 mm (holotype 1.8 mm).</p><p>Coloration. Frons brown with median portion indistinctly paler, clypeus reddish brown. Pronotum brown with vaguely pale reddish anterolateral corners. Elytral uniformly brown, with large vaguely limited yellow apical spot reaching apical 0.5–0.3 on intervals 2–7 and ca. apical eighth on intervals 8–10. Ventral surface of head and prothorax reddish brown, meso- and metaventrite brown, abdominal ventrites 1–4 brown with pale lateral spots, ventrite 5 entirely pale, legs pale reddish.</p><p>External morphology. Clypeus with moderately coarse and rather dense punctation consisting of uniformlysized rounded punctures separated from each other by ca. 1–2× puncture diameter. Punctation of frons similar to that on clypeus, but consisting of punctures of two slightly different sizes. Interstices on head without microsculpture. Larger punctures on pronotum rounded, shallow, much larger than small punctures; small punctures scar-like, divided from each other by ca. 1–3× puncture width. Pronotal interstices without microsculpture. Prosternum with distinct median carina. Elytral series consisting of large, shallow punctures; interval punctation with rather fine semicircular punctures much smaller than serial ones, with sparsely intermixed slightly larger setiferous punctures of the same shape; interstices without microsculpture. Elytral series weakly impressed. Preepisternal elevation of mesothorax with posterolateral pits. Femoral lines on metaventrite indistinctly angulate, median portion of metaventrite bearing moderately coarse but sparse setiferous punctation, interstices without microsculpture; lateral portions with very coarse and dense, densely pubescent punctation. Anterior tibia rather wide, outer margin continually arcuate, outer series of spines not interrupted.</p><p>Male genitalia (Fig. 38). Tegmen 1.1 mm long, median lobe 1.1 mm long. Phallobase ca. 2× as long as parameres, bearing small, slightly asymmetrical and indistinctly detached basal manubrium. Median lobe rather wide in basal three fourths, distinctly narrowed at apical fourth and then gradually narrowing to widely triangular apical portion, blunt at very apex; lateral pubescent lobes very distinct subapically. Sternite 9 with large V-shaped apical emargination.</p><p>Variation. A very low variation was observed in the coloration of elytra (concerning the extent and distinctness of the apical elytral yellow spot, Fig. 66) and body size (see description). Otherwise the examined specimens are very constant in all characters of taxonomic importance including of the morphology of the male genitalia.</p><p>Etymology. Named after Sandakan Division in Sabah, in which two localities of this new species are located.</p><p>Biology. Specimens examined were collected from various kinds of rotting plant matter (cassava skins, vegetable garden refuse and leaf litter).</p><p>Distribution. Known from three close localities in central Sabah in northern Borneo.</p><p>Discussion. Pachysternum sandacanum seems to belong to the P. a p i c a t u m complex (based on the presence of deep pits on preepisternal elevation of mesothorax) whose taxonomy is not completely resolved in this paper, mainly because of P. apicatum is here understood as a polymorphic species but may actually consist of several species/subspecies. Following this concept, Pachysternum sandacanum may seem to be a part of the widely understood P. apicatum on the first view. However, its syntopic co-occurrence with the Bornean form of P. apicatum (uniformly reddish brown to brown in coloration, with rather deeply bisinuate anterior tibia, but with the male genitalia identical with the typical P. apicatum), supports the separate status of P. sandacanum .

Pale specimens of this species may be easily distinguished by the combination of uniformly dark pronotal disc with widely pale lateral margins, elytra with distinct subbasal pale spots on intervals 2– 5(-6), pale apical portion of elytra and slightly but distinctly bisinuate outer margin of anterior tibia (Fig. 48). These specimens of P. stevensi may resemble dark specimens of P. cardoni (which may be distinguished mainly by larger and wider body form, pale median portion of frons and in some cases also by partly reduced microsculpture of elytra) and P. kubani (for diagnostic characters see couplet 12 of the identification key). Uniformly colored specimens of P. stevensi (i.e. those without clearly defined pale spots on elytra) are characterized by the combination of bisinuate outer margin of anterior tibia and strong microsculpture of elytra. These specimens may resemble P. rugosum by their coloration (outer margin of anterior tibia is continually arcuate in P. rugosum, bisinuate in P. s t e - vensi), P. coomani by the general coloration (outer margin of anterior tibia is continually arcuate in P. coomani which also has wide median lobe of the aedeagus nearly parallel-sided throughout, tibiae are bisinuate and the median lobe gradually narrowing apicad in P. stevensi), and some morphotypes of P. a p i c a t u m (these may vary in the characters above, but their elytral interstices lack microsculpture, whereas microsculpture is very strong in P. stevensi).</p><p>Redescription. Body widely oval, shape of elytra sexually dimorphic, female with distinctly pronounced humeral portion of elytra. Body length 2.1–3.3 mm; body width 1.4–2.1 mm.</p><p>Coloration. Head uniformly black, only with pale reddish transverse ridge. Pronotum black, with widely pale reddish lateral margins, pale area widest anteriorly, narrowest at posterolateral corner. General coloration of elytral black; interval 1 black throughout, intervals 2–5 with large vaguely defined pale reddish spots subbasally, apical third of elytra pale yellowish, lateral margin of elytron more or less pale throughout. Ventral surface of head dark brown, thoracic sclerites black, abdominal ventrites 1–4 reddish brown in posterior portion, entire ventrite 5 pale, legs pale reddish.</p><p>External morphology. Clypeus with moderately coarse dense punctation consisting of uniformly-sized rounded punctures separated from each other by ca. 1–2× puncture diameter. Punctation of frons similar to that on clypeus. Interstices on head without microsculpture. Larger punctures on pronotum rounded, shallow, much larger than small punctures; small punctures scar-like, divided from each other by ca. 1–1.5× puncture width. Pronotal interstices without microsculpture. Prosternum with very distinct median carina. Elytral series consisting of large, shallow punctures; interval punctation with rather fine semicircular punctures much smaller than serial ones, with sparsely intermixed slightly larger setiferous punctures of the same shape; interstices with strong mesh-like microsculpture. Elytral series weakly impressed. Preepisternal elevation of mesothorax without posterolateral pits. Femoral lines on metaventrite indistinctly angulate, median portion of metaventrite bearing fine, moderately dense setiferous punctation, interstices without microsculpture; lateral portions with very coarse and dense, densely pubescent punctation. Anterior tibia rather wide, outer margin distinctly bisinuate, outer series of spines slightly interrupted.</p><p>Male genitalia (Fig. 34). Tegmen 1.2 mm long, median lobe 1.2 mm long. Phallobase 2× as long as parameres, bearing large, slightly to strongly asymmetrical and distinctly detached basal manubrium. Median lobe rather narrow, widest in basal third, weakly narrowing apicad, apex narrowly rounded; gonopore subapical, rather indistinct; lateral pubescent lobes indistinct even subapically. Sternite 9 entire or with moderately large V-shaped apical emargination (see Variation).</p><p>Variation. Dorsal coloration varies considerably in the distinctiveness of the elytral pale basal as well as apical spots. Typically, the basal spots merge in one triangular, more or less sharply delimited subbasal reddish spot and the elytral apex is yellowish (Figs. 68a–f). In many specimens both basal and apical spots are more vaguely delimited and not so distinct, and in extreme cases the elytra are uniformly brown without any trace of paler spots (this extreme kind of coloration bear the types of P. nigritum examined, Fig. 68h). Similar variability concerns the pale areas on lateral margins of pronotum, but even in the specimens with uniformly colored elytra the sides of pronotum are still distinctly and rather widely paler, even though the pale spot is very vaguely delimited from the dark brown pronotal disc. Very apparent variation surprisingly concerns the shape of the median portion of male sternite 9, which may vary from deeply emarginated (Fig. 34d) through shallowly emarginated to entirely rounded apically (Fig. 34e). The shape varies even between the specimens from the same region (e.g., Guangdong province in China: the examined paratype of P. nigritum has entire, but the specimen from Datian Ding Mt. deeply emarginate median lobe of sternite 9) or in the specimens from the single collecting event (the sternite 9 varies from entirely rounded to deeply emarginate in specimens from Vietnam: Buon Luoi). The shape of the sternite 9 varies irrespectively to the coloration variability. As we failed to find any other morphological differences between the specimens with different shape of sternite 9 and as the intermediate shapes also occur, we consider this variation as intraspecific. No males were examined from the type locality in the Tamil Nadu state in India, but all dissected males from Kunjappanai (Nilgiri Hills) have deeply emarginate sternite 9.</p><p>Following the above variation patterns of P. stevensi, P. nigritum is clearly only a variation of P. stevensi without distinct spots and has to be therefore consider as a junior synonym of the latter species. Except of the difference in coloration and the shape of male sternite 9, both paratypes of P. nigritum completely correspond with other specimens of P. stevensi examined for this study.</p><p>Biology. A portion of the specimens examined were collected in cow excrements, no habitat data are provided for remaining material used for this study.</p><p>Distribution. Known from Himalaya, southern China and continental SE Asia (but not reaching Malayan peninsula). An isolated population seems to exist in southern India (Tamil Nadu), and no records are available from the rest of Indian subcontinent including the lowland northern India.</p></div>	https://treatment.plazi.org/id/03E687BAFFE5F333FF5EFC790F6CC394	Public Domain	No known copyright restrictions apply.

A. Skale.</p><p>Differential diagnosis. Pachysternum sulawesicum may be easily distinguished from other species by the coloration of elytra (which typically bears large apical horse shoe-shaped pale spot and small humeral pale spot), continually arcuate outer margin of anterior tibia and entirely dark pronotal disc. Pale specimens of P. sulawesicum may resemble dark specimens of P. nigrovittatum by the elytral pattern, but may be easily distinguished by the shape of anterior tibiae and coloration of pronotum mentioned above (anterior tibiae are distinctly bisinuate on outer margin and pronotum is pale with large M-shape spot in P. nigrovittatum). Dark specimens of P. sulawesicum are rather similar to dark specimens of P. kubani, but may be distinguished from the latter by uniformly arcuate anterior tibia (deeply sinuate in P. kubani). Distinct (but vaguely limited) humeral spot along with pale apical portion of elytra is rarely present also in the specimens of P. apicatum, which may be distinguished by at least slightly angulate outer margin of anterior tibia and by the shape of the median lobe (wide in basal third and then narrowing apicad in P. apicatum, nearly parallel-sided throughout in P. sulawesicum).</p><p>Redescription. Body widely oval, shape of elytra slightly sexually dimorphic, female with distinctly pronounced humeral portion of elytra. Body length 2.5–3.6 mm (holotype: 2.6 mm); body width 1.5–2.2 mm (holotype 1.9 mm).</p><p>Coloration. Clypeus and median portion of frons pale reddish, lateral portions of frons dark brown. Pronotum dark brown with widely reddish anterolateral corners and median portion of anterior margin. Elytron dark brown with sharply delimited pale reddish spot at the base of elytral interval 5, small pale reddish spot in anterolateral corner, and large horseshoe-shaped pale reddish spot at apex; the apical spot reaching more anteriad on intervals 2, 5– 7 and 10. Ventral surface of head brown, thoracic sclerites dark brown, legs and abdominal ventrite 5 pale reddish.</p><p>External morphology. Clypeus with moderately coarse and rather sparse punctation consisting of nearly uniform-sized punctures divided by ca. 2–3× of puncture diameter. Frons with slightly coarser punctation than on clypeus, consisting of punctures of two slightly different sizes separated by ca. by 1.5–3× of puncture diameter. Interstices without microsculpture. Larger punctures on pronotum rounded, much larger than small punctures, small punctures scar-like, divided by ca. 2–3× of puncture width. Pronotal interstices without microsculpture. Prosternum with weak or nearly indistinct median carina. Elytral series consisting of large, shallow punctures; interval punctation with moderately large semicircular punctures much smaller than serial ones, interval punctation consisting of two slightly different sizes of punctures, larger punctures setiferous; interstices with moderately developed mesh-like microsculpture. Elytral series indistinctly impressed. Preepisternal elevation of mesothorax without posterolateral pits. Femoral lines on metaventrite slightly angulate; median portion of metaventrite bearing moderately large and dense setiferous punctation, interstices without microsculpture; lateral portions with very coarse and dense, densely pubescent punctation. Outer margin of anterior tibia very slightly bisinuate, outer series of spines not interrupted.</p><p>Male genitalia (Fig. 35). Tegmen and median lobe 1.3 mm long. Phallobase ca. twice as long as parameres, slightly asymmetrical basally, without distinctly detached manubrium. Median lobe widest at midlength, weakly narrowing apicad, apex narrowly rounded; gonopore subapical, rather indistinct; lateral pubescent lobes narrow, developed only subapically. Median projection of sternite 9 with deep V-shaped emargination apically.</p><p>Variation. Rather variable species, the variability concerns the coloration, dorsal microsculpture and the height of median carina of the prosternal plate. The additional specimen examined (Batu Putih env.) has the pale spots of elytra much more extended than the type specimens redescribed above, with the elytron colored as follows (Fig. 70 c): interval 1 black, whole interval 2 pale reddish, basal pale spots present on intervals 2–4 and 7–10; basal spot similar to type specimens, but reaching more anteriad on intervals 3–6; lateral margin of elytron widely pale reddish throughout. The coloration of the pronotum and the head of this specimen corresponds with the type specimens redescribed above. Dorsal microsculpture of elytral intervals varies from moderately distinct (in the holotype and the additional specimen from Batu Putih env.) to rather indistinct (in some paratypes). Median carina of prosternal plate is rather obsolete in some specimens and therefore seemingly absent, but it may be still detected on SEM micrographs of these specimens.</p><p>Biology. Unknown.</p><p>Distribution. Known from two localities in northernmost Sulawesi and one locality in southern Sulawesi. Most probably widely distributed throughout the island.</p></div>	https://treatment.plazi.org/id/03E687BAFFE1F337FF5EFF4C0F0EC5D0	Public Domain	No known copyright restrictions apply.

The species bears all diagnostic characters of the Australocyon pilocnemoides species group mentioned by Hansen (2003), and moreover differs from Pachysternum species by the antennal grooves not reaching the lateral margin of hypomeron, and metaventrite lacking any trace of the femoral lines. Morphology of its genitalia (see Hebauer 2002a, Fig. 22) also do not correspond with the Pachysternum species, but largely agree with those illustrated by Hansen (2003, Figs. 18–21) for the species of the Australocyon pilocnemoides group. For that reason, the species is transferred here to the genus Australocyon .</p><p>Australocyon keralensis may be diagnosed as follows: dorsal surface uniformly dark brown; antennal club unicolored; pronotum without sublateral depressions; posterolateral corners of pronotum bluntly rounded; pronotal punctation moderately coarse but sparse, consisting of punctures of two slightly different sizes; pronotal interstices bearing strong mesh-like microsculpture; elytra evenly convex, not humpy in humeral areas. Based on the key provided by Hansen (2003), the species seems to be very similar especially to A. pilocnemoides Hansen, 2003 and A. puncticollis Hansen, 2003 .</p></div>	https://treatment.plazi.org/id/03E687BAFFE3F337FF5EFD560DC5C131	Public Domain	No known copyright restrictions apply.

There is a single species of Megasternum occurring on the Japanese islands which differs from the continental M. concinnum (Marsham, 1803) by finely but distinctly punctate ventrites 2–5 (impunctate in M. concinnum). The Japanese species was for the first time recognized and diagnosed as separate from M. concinnum by Sharp (1874), who called it Megasternum gibbulum Motschulsky, 1866 even though he did not examine the Motschulsky’s types and noticed some discordance between his Japanese specimens and Motschulsky’s (1866) short description of M. gibbulum . Sharp’s (1874) interpretation of M. gibbulum was followed by all subsequent Japanese authors. While working on the keys to identification of the Hydrophilidae of Russian Far East, A. G. Shatrovskiy reexamined the types of Megasternum gibbulum in Motschulsky collection, designated the lectotype of this species, correctly recognized that the type specimens do not belong to the genus Megasternum but Pachysternum and realized that the Japanese species of Megasternum is therefore unnamed. For that reason, he described the Japanese species as Megasternum japonicum (see Shatrovskiy 1989, 1992). Unfortunately, the transfer of Megasternum gibbulum to Pachysternum, its synonymization with P. haemorrhoum and the designation of its lectotype was never published, and the reasons for describing Megasternum japonicum remained therefore unexplained. For that reason, Hoshina &amp; Satô (2005) synonymized Megasternum japonicum with M. gibbulum, considering some paratypes of M. japonicum from the Lewis collection in BMNH as being at the same time syntypes of M. gibbulum . All paratypes deposited in BMNH and mentioned by Shatrovskiy (1992) were, however, collected after the description of M. gibbulum by Motschulsky (1866) and therefore cannot be syntypes of the latter species. Hoshina &amp; Satô (2005) did not examine the specimens of M. gibbulum from the Motschulsky collection deposited in ZMUM, which are all conspecific with Pachysternum haemorrhoum (see above under this species). For that reason, the synonymy of Megasternum japonicum with M. gibbulum proposed by Hoshina &amp; Satô (2005) is incorrect, and Megasternum japonicum has to be resurrected as a valid name for the Japanese species of the genus Megasternum .</p></div>	https://treatment.plazi.org/id/03E687BAFFE3F328FF5EFABE0D86C6B1	Public Domain	No known copyright restrictions apply.
