The articulatory area is marginate on each side, and is bounded anteriorly by a transverse strip of cuticle to which the intersegmental membrane of the propodeal foramen is attached.</p><p>21 Stridulitrum present on pretergite of first gastral segment (abdominal segment 4).</p><p>22 Tergite of abdominal segment 4 does not overlap the sternite on the ventral surface of the gaster.</p><p>23 Gastral shoulders weakly present to absent.</p><p>24 Sting well developed and functional, simple, without an apical lamellate appendage, never spatulate, never thread-like.</p><p>25 Main pilosity of head and body simple, frequently, but not universally, absent from propodeal dorsum.</p><p>Comments on Eutetramorium group worker characters</p><p>It is not yet possible to indicate any unequivocal morphological apomorphies of this endemic Madagascan group. The subfamily Myrmicinae is huge, with frequent convergence and parallelism among characters so that analogues of each appear to have been developed independently several to many times. As a result, the best that can be attempted here is an inclusive diagnosis. However, the group is retrieved as an unambiguous monophyletic clade by molecular techniques (Prof. Philip S. Ward, pers. com., currently unpublished). The numbers below refer to the character numbers listed above.</p><p>2 Palp formula 5,3 is universal in the group except in Eutetramorium itself. There, two species have PF 4,3, and one has PF 4,2. A palp formula of 5,3 is common in Myrmicinae, occurring in 33 of 136 genera (Bolton, 2003). Palp formula 4,3 is slightly less commonly encountered in the subfamily (28 genera out of 136), but PF 4,2 is rare, being predominant only in the Neotropical Attini and in a few species scattered through six other genera.</p><p>3 The stipital crest is present in all genera of the group except Royidris . In Eutetramorium and Vitsika it is coarse, and the area of the stipes distal of the crest is depressed and concave. In Royidris the crest is very reduced, functionally absent, at best visible as a weak line across the stipes. In the other genera the crest is fine and curves across the stipes, usually just distal of its midlength, and is often more strongly developed at the median border of the stipes (adjacent to the labium), tending to decrease in definition as the lateral stipital border is approached.</p><p>4 The clypeal apron is very reduced only in Malagidris sofina . An unpaired seta at the midpoint of the anterior clypeal margin is characteristic of Malagadris, Royidris and Vitsika; a pair of short, fine setae that straddle the midpoint occurs in Myrmisaraka, where the margin is also notched at the midpoint, and in Eutetramorium, where the paired setae are on each side of a median tooth or prominence.</p><p>6 In most Vistika species, and in Eutetramorium, the torulus lobe is concealed by the broad frontal lobe on each side.</p><p>7 Elongate frontal carinae and antennal scrobes are developed only in Vitsika, elsewhere the frontal carinae are represented only by the frontal lobes.</p><p>8 The antennal club is usually 3-segmented. It is 4-segmented in the Royidris notorthotenes group, and weakly 5-segmented only in Myrmisaraka producta .</p><p>13 On the ventral mesosoma there is a transverse depression or trench, U-shaped in section, on each side of a median longitudinal ridge of cuticle, located at the anterior end of the mesothorax just posterior to the procoxal cavities. The trench is commonly developed in myrmicines, but in numerous genera and groups of genera it is narrow, reduced or poorly defined (e.g. Atopomyrmex, Gauromyrmex, Myrmicaria, Ocymyrmex, the Leptothorax and Temnothorax genus groups), and in some it is extremely reduced or absent (e.g. Tetramorium, Cephalotes, Cataulacus). The various developmental states of this structure, and their phylogenetic significance, await a proper investigation.</p><p>14 In Eutetramorium mocquerysi a large metasternal process is present, and there is also a bidentate mesosternal process.</p><p>17 In almost all species of the group a single mesotibial and metatibial spur is present, and obviously distinguishable from the setae at the tibial apices. However, in smaller species of Vitsika and Royidris reduction of the spurs is extreme, and they become indistinguishable from the apical setae under light microscopy.</p><p>20 The comparative morphology of the propodeal-petiolar articulation has never been investigated, but shows considerable variation through the Myrmicinae . The structure as described above for the Eutetramorium group appears most closely paralleled in Temnothorax and Huberia .</p><p>22 and 23 In numerous myrmicines, for example the solenopsidines and pheidolines (among others, see Bolton, 2003, for distribution) the fourth abdominal (first gastral) tergite strongly overlaps the sternite ventrally, so much so that in ventral view the tergite is extensively represented on the ventral surface. The tergite overlaps the sternite from each side and the inner margins of the tergite form a pair of convex longitudinal arcs in ventral view. Because of this the visible sternite appears narrowest at about its midlength and broadens posteriorly as the tergal arcs diverge. Anteroventrally, as the convex arcs of the tergal margins diverge, before suddenly curving in to the articulation of postpetiole and first gastral segment, the sternite tends to project forward beyond the margins of the tergite, to form a pair of shoulders that project anteriorly, one on each side of the articulation. These anterior projections of the sternite are frequently visible in dorsal view and constitute the gastral shoulders. The alternative, without the developments just described, occurs in the Eutetramorium group, and in many other groups. In ventral view the fourth abdominal (first gastral) tergite margins the sternite laterally, but does not extensively overlap onto the ventral surface. The inner margins of the tergite tend to be convex to more or less straight, and usually diverge posteriorly. Thus the visible sternite does not appear narrowest at about its midlength, but instead usually broadens posteriorly. Anteroventrally, the tergal margins converge evenly to the articulation of the postpetiole with the first gastral segment, and the sternite on each side does not project forward beyond the margins of the tergite. As a result there are no shoulders that project anteriorly on each side.</p><p>The myrmicine genus that morphologically corresponds most closely to the Eutetramorium group definition above appears to be Huberia Forel, a strange little genus of only two species that is confined to New Zealand (Brown, 1958; Don, 2007). Its type-species, H. striata (F. Smith), largely matches the definition of the Eutetramorium group, but differs significantly as the upper lobe of the torulus projects anterior to the widest point of the frontal lobe, there is no clypeal apron, a large metasternal process is present (as is a mesosternal process), the antenna has 11 segments, the vestigial track of the promesonotal suture is retained across the dorsum of the mesosoma, and the propodeum is relatively short.</p></div>	https://treatment.plazi.org/id/9A1090C5597F7B0CB9DE8C5B54FF24B9	Public Domain	No known copyright restrictions apply.

A-f2 long, not merely a stub distal of cu-a. In monticellii queens cu-a is retracted toward the wing base and arises from M+Cu, proximal of the point where it divides into Mf1 and Cuf1-2.

Initially, Emery (1912, 1914) was of the opinion that the genus was referable to the tribe Myrmecinini, but Ashmead (1905) and Wheeler (1910) had already referred it to Tetramoriini, an opinion that Emery (1915b, 1924) also came to accept. Bolton (1976) excluded Eutetramorium from Tetramoriini on morphological grounds, and tentatively transferred it to Myrmicini . This placement persisted until recently, when a molecular analysis of Myrmicini by Jansen &amp; Savolainen (2010) showed that the monophyly of the tribe was dubious, and that Eutetramorium formed a clade with Huberia . The yet unpublished, more detailed, DNA analysis of Myrmicinae by Philip S. Ward has established that Eutetramorium belongs in a strongly supported, endemic Madagascan clade that also includes the other four genera revised here.</p><p>Synopsis of Eutetramorium species</p><p>mocquerysi Emery, 1899</p><p>monticellii Emery, 1899</p><p>parvum Bolton &amp; Fisher sp. n.</p><p>Key to Eutetramorium species (workers)</p><p>1 Much smaller, yellow species (Fig. 7), HW 0.56-0.59, SL 0.44-0.48, MfL 0.52-0.54.

The alate queen matches the description of the worker except for its conspicuous ocelli and the structure of the enlarged mesosoma, where there is a full complement of flight sclerites and a broad sulcus across the mesopleuron. The ergatoid forms match the definition of the worker but with ocelli variably developed. In alperti and the single known ergatoid of jugum ocelli are absent, although a vague pit-like depression in one alperti ergatoid may indicate the last vestige of the median ocellus. Among the known ergatoids of sofina some retain three distinct ocelli, while others exhibit only a reduced median ocellus. The mesonotum is somewhat larger and better defined than in the worker, with a fully fused but more obvious promesonotal suture across the dorsum. The mesopleuron shows a reduced or absent transverse sulcus. The propodeal spines are shorter and stouter than in the respective workers, the postpetiole is more swollen and the gaster is more voluminous. Venation: see under male.</p><p>Diagnosis of male</p><p>Males taken in association with workers are known for alperti, belti, jugum and sofina . In addition, males of two more species that appear to belong in this genus are known. One of them is tentatively associated with dulcis here, but this remains to be confirmed; the other does not associate with any known worker but appears morphologically closest to jugum, it is discussed there. Slightly smaller than conspecific worker. Mandible triangular and strongly dentate, with 6-11 sharp teeth. Palp formula 5,3. Stipital crest present on maxilla. Antenna with 13 segments, long and filiform. SI 42-79. First funicular segment short, not globular, about one quarter to one half the length of the second funicular segment. In full-face view eye located in front of midlength of head capsule. Ocelli conspicuous. Occipital carina sharp, forming a distinct crest. Mesotibia and metatibia each with a single simple spur. Notauli very reduced or absent. Mesopleuron with a marked transverse sulcus. Mesoscutum convex in profile, the mesoscutum and mesoscutellum elevated, much higher than the propodeal dorsum, which is depressed and slopes downward posteriorly. Propodeum unarmed, the spiracle high on the side and at about the midlength, or slightly in front of the midlength, of the sclerite; propodeal lobes conspicuous, rounded. Petiole with a long anterior peduncle and a low node, the spiracle at or behind the midlength of the peduncle, but in front of the level of the node. Subpetiolar process present, small. Parameres large. Cerci present.</p><p>Forewing venation (based on males as available belti queen specimens are dealate). Rs f4-5 does not meet Rf3 on anterior margin of wing (= marginal cell open). 2rs-m absent. 1m-cu present. Fusion of Rs+M extended distally, so that 1m-cu arises from Rs+M, not from M. Rsf3 absent (Rs+M divides into Rsf4-5 and Mf3-4 at or distal of the junction with 2r-rs). Af2 a mere stub distal of cu-a; the latter is retracted and arises from M+Cu, proximal of the point where it divides into Mf1 and Cuf1-2.</p><p>Comments on Malagidris</p><p>The type-species of this genus, belti (Forel, 1895), has had a moderately varied taxonomic history. It was originally described in the genus Aphaenogaster Mayr (1853), even though Forel remarked on its 3-segmented antennal club, rather than 4 as is usual in that genus. This character, coupled with the presence of angulate humeri and a queen with a depressed mesosoma, caused Emery (1915a: 68) to exclud belti from Aphaenogaster and transfer it to Atopula Emery (1912). Forel (1917: 234) decided that Atopula was artificial, "composed of disparate species," and established the genus Brunella to include only belti . The component species of Atopula were later dispersed to other genera by Bolton (1976: 362), who retained genus Brunella as its "affinities are unclear." Later however, Bolton (1982: 341) synonymised Brunella under Aphaenogaster, thus returning belti to its original generic combination.</p><p>Extensive recent sampling of the Madagascan ant fauna by Brian Fisher and associates has made it clear that this synonymy was incorrect. The discovery of several species referable to Forel’s Brunella has allowed the diagnosis of a distinct group of Madagascan endemics, which are convergent in some characters with Aphaenogaster but certainly not congeneric with it. The final act of this history has been the realisation that Brunella Forel (1917) is the junior homonym of a crustacean genus Brunella G.W. Smith (1909), from Tasmania. No replacement name was essential for Brunella Forel while it was a junior synonym, but now that it is revived from synonymy a replacement name is necessary: Malagidris nom . n.</p><p>The larger, more gracile species (e.g. alperti, galokoa, jugum, sofina) of Malagidris are remarkably convergent on the widely distributed genus Aphaenogaster . However, all species of Malagidris have two critical features never exhibited by Aphaenogaster species. First, the midpoint of the anterior clypeal margin of Malagidris has a single, stout, unpaired seta. In Aphaenogaster there is always a conspicuous pair of setae, one on each side of the midpoint of the anterior clypeal margin. Second, Aphaenogaster species do not have the characteristic structure of the anteroventral peduncle of the petiole, as described under the definition of Eutetramorium group. In addition to these, Malagidris always has the following: a transverse crest present on the stipes of the maxilla; a 3-segmented antennal club; a subpetiolar process present; a strongly developed sting; the anterior clypeal margin convex at the midpoint. In Aphaenogaster, by contrast, the stipes usually lacks a crest (a crest is incompletely and weaky developed in a few species, strong only in A. relicta Wheeler &amp; Mann, from Haiti, which may not be properly referable to Aphaenogaster), usually has a 4-segmented antennal club (5-segmented to gradually incrassate in some species but never 3-segmented), lacks a subpetiolar process, has a very weakly developed or vestigial sting, and usually (but not always) has the midpoint of the anterior clypeal margin concave or indented.</p><p>Synopsis of Malagidris species alperti Bolton &amp; Fisher sp. n.</p><p>belti (Forel, 1895)</p><p>dulcis Bolton &amp; Fisher sp. n.</p><p>galokoa Bolton &amp; Fisher sp. n.</p><p>jugum Bolton &amp; Fisher sp. n.</p><p>sofina Bolton &amp; Fisher sp. n.</p><p>Key to Malagidris species (workers)</p><p>1 Head relatively broad (CI 81-84).

Propodeal spines long in profile (0.48-0.58); propodeal declivity unsculptured. Side of mesosoma rugose to reticulate-rugulose, but not as strongly sculptured as the dorsum; sculpture partially to mostly effaced on mesopleuron and metapleuron. Metafemur long and slender, MfL 1.86-2.00 (MfL/HW</p><p>1.96-2.41, MfL/MfH 6.30-8.30). Peduncle of petiole long and slender, downcurved in profile and with a small, dentiform anteroventral process. Subpetiolar process not followed by a cuticular crest along the mid-ventral surface of the peduncle. Petiole node in profile narrowly conical, vertical to slightly inclined anteriorly; acute apically. In posterior view the sides of the petiole node converge in their upper halves, the short apical margin is narrowly rounded to flattened. Petiole node with faint superficial punctulate sculpture, almost effaced in some. Postpetiole in profile convex dorsally, about 1.20-1.48 times longer than high; in dorsal view distinctly longer than broad; maximum dorsal width of postpetiole 0.37-0.46, very slightly less than its height. Dorsum of postpetiole node finely punctulate and with a few weak superficial rugulae. Base of first gastral tergite at most with superficial basigastral costulae, sometimes entirely effaced; tergite otherwise unsculptured.</p><p>Pilosity: with head in full-face view the side, both in front of and behind the eye, without projecting setae; with head in profile the dorsum behind the highest point with 2-3 pairs of setae that are inclined anteriorly, followed by a transverse row of 4 setae closest to the posterior margin (rarely this row is reduced to a widely separated pair, or is absent); pronotal dorsum without setae; mesonotum anteriorly with 1 pair, without setae at the metanotal groove; propodeal dorsum lacks setae; ventral surface of metafemur lacks setae; petiole node with a pair of setae on its posterior face; postpetiole with 1 pair dorsally and with a transverse row of 4 posteriorly; gaster with numerous short simple setae.

Propodeal spine length ca 0.46, but the spines stouter than in the worker. Postpetiole length 0.60, width 0.58-0.60, height 0.60-0.63. Maximum width of first gastral tergite 1.50-1.60 (as opposed to &lt;1.30 in worker). Most dimensions are within the worker ranges, but the scape is relatively shorter, and the metafemur is both absolutely and relatively shorter. In general the ergatoid matches the worker description, but the pronotal sculpture is more sharply reticulate-rugose, and the humeral angles are more pronounced. Pilosity as worker but head without the posterior transverse row (this may have been abraded away in the single specimen available). Ocelli absent or at most with a pit-like vestige of the median ocellus among the cephalic sculpture.</p><p>MALE. Mandible with 8-9 sharp teeth. CI 73-74, SI 45-48, MfL ca 1.25 (2 measured). First funicular segment of antenna less than 0.50 times the length of the second segment. EL/HW 0.45-0.46. With head in profile the dorsal outline behind the posterior ocelli slopes down to the occipital carina, the surface not vertical immediately behind the ocelli. With mesosoma in dorsal view the pronotum forms a visible anterior arc in front of the mesoscutum. Notauli absent. Peduncle of petiole with spiracles borne on low prominences, in dorsal view the distance across them slightly less than the maximum width of the node. Postpetiole in dorsal view slender, I.89-1.92 x longer than broad.</p><p>Three males are known, all from the Andrakaraka series noted below (CASC). In all of them the metatibiae are strangely deformed, and in most there is some degree of deformity to the femora, tibiae and basitarsi of the middle and hind legs. It is not considered that this is a normal morphological character, but rather is the result of a genetic aberration or the result of parasitoid attack in a pre-imaginal stage. The deformities are not seen in any workers or ergatoids from the same series.</p><p>Holotype worker, Madagascar: 5 km. SW Antalaha [Prov. Antsiranana], 50 m., 14°56 ’17” S, 50°15 ’42” E, 27.ii.1991.

Its possession of the cephalic setal array described above, combined with 4 mesonotal pairs, including one at the metanotal groove, and at least one pair on the propodeum, render it immediately recognisable. In addition, it is the only species to have the metafemur relatively deep (MfL/MfH 4.60-5.10), a ratio matched only by belti (MfL/MfH 4.62-5.22), and far below those seen in the more attenuated species of the genus, where the collective MfL/MfH is 5.77 to&gt; 12.00.</p><p>There is a possibility that dulcis, as presently constituted, includes more than one cryptic species. Of special interest is the variation seen in the degree of elevation of the propodeal spines, and also their length. In terms of elevation the spine in profile varies from about 45° to almost vertical. At present this is not being treated as significant, but the acquisition of more material may necessitate a re-examination. Whatever the elevation of the spine, most specimens have a propodeal spine length of 0.18-0.26. However, there is a single specimen in CASC, collected by P.S. Ward and with collection data noted below, which has a propodeal spine length of 0.38, well above the usual range. This specimen also has a slightly broader head (CI 74), slightly shorter scape (SI 145), deeper metafemur (MfL/MfH 5.50) and a broader postpetiole (length/height ratio 1.05) than is usual. As only one such specimen is available, and because its other characters match the dulcis material, it is retained within dulcis, but this should be re-assessed if similar material is ever rediscovered.</p><p>M. dulcis occurs under stones and in leaf litter samples in rainforest. It has also been discovered in littoral forest, and once in tropical dry forest where it was foraging on the ground.</p><p>Non-paratypic material examined. Madagascar: Prov.

Peduncle of petiole slender, slightly downcurved in profile and with a small, dentiform anteroventral process. Subpetiolar process not followed by a cuticular crest along the mid-ventral surface of the peduncle. Petiole node in profile broad, bluntly rounded dorsally, not acute apically. Petiole node with very weak superficial punctulate to shagreenate sculpture, almost effaced in places. Postpetiole in profile shallowly convex dorsally, about 1.25-1.39 times longer than high; in dorsal view distinctly longer than broad; maximum dorsal width of postpetiole ca 0.34-0.36, about equal to its height. Dorsum of postpetiole node finely reticulate-punctulate. First gastral tergite unsculptured. Full adult colour yellow to yellow-brown.</p><p>Pilosity: with head in full-face view the side in front of the eye with 0-1 projecting setae, the side behind the eye with 0-1 projecting setae, never with setae that project outward from below the eye itself; with head in profile the dorsum behind the highest point with 3-5 pairs of setae that are inclined anteriorly, followed by a transverse row of 4 setae, or a widely separated pair, closest to the posterior margin; pronotal dorsum with 1-2 pairs of setae, when present the posterior pair close to the mesonotal margin; mesonotum with 1-2 pairs; without setae at the metanotal groove; propodeal dorsum without setae; ventral surface of metafemur with 1-2 setae, in the basal half; petiole node with a pair of setae on its posterior face; postpetiole with 1 pair of setae dorsally and with a row of 4 posteriorly; gaster with numerous simple setae.</p><p>QUEEN (gyne) and MALE: unknown.</p><p>Holotype worker, Madagascar: Galoko chain, Mont Galoko, 980 m., -13.5888, 48.72864 +/- 200 m., 18.ii.2013, montane forest, BLF 30793, CASENT0344994 (B.L Fisher et al.)

The only other species of Malagidris which may exhibit upcurved propodeal spines is dulcis, but here, even at its most pronounced, the curvature is slight, and the apices of the spines never point anterodorsally. Confusion of the two is unlikely, but for confirmation of identity dulcis is an obviously more densely setose species, with 1-2 setae projecting out from below the eye, 4-5 setae projecting from the side of the head behind the eye, a pair of setae present at the metanotal groove and a pair present on the propodeal dorsum.</p><p>Non-paratypic material examined.

Median clypeal seta stout, in dorsal view usually arising from a small tubercle at the midpoint of a false anterior margin (tubercle may be effaced in smallest workers); below the seta there is a short, vertical or reflexed section of the clypeus that descends to the true anterior margin. In profile the clypeal setae appear to arise from a ridge that is well above the true anterior margin of the clypeus. Scapes long (SI&gt; 160), with minute pubescence but lacking standing setae. Club segments of funiculus long and slender, distinctly longer than broad. EL 0.22-0.28 (EL/HW 0.24-0.26). With head in profile the dorsal outline above and behind the eye is more or less flat, or at most only extremely shallowly concave. With head in full-face view, sides behind the eyes elongate, shallowly convex and weakly convergent posteriorly, passing into the posterior margin through a short angle; posterior margin shallowly concave and the occipital carina raised into a translucent cuticular flange that is widest medially. Dorsum of head predominantly longitudinally rugose, with occasional anastomoses; posteriorly the rugae decreasing in strength and the number of anastomoses increasing. Spaces between the rugae finely punctulate, especially on the anterior half. Ventral surface of head with shallow, arched transverse costulae. Dorsum of mesosoma sharply rugose, the strongest rugae transverse; with some reticulation on the pronotum; spaces between the rugae mostly smooth, not reticulate-punctulate. In dorsal view the lower sides of the pronotum flared outward above the coxal articulations, so that the maximum pronotal width, across the flared portion, is 1.25-1.30 times greater than across the humeri. Propodeal spines long in profile (0.45-0.60). Propodeal declivity unsculptured, or at most with a vestige of transverse sculpture between the bases of the spines. Side of mesosoma rugose to reticulate-rugose. Metafemur long and slender, MfL 2.04-2.76 (MfL/ HW 2.17-2.65, MfL/MfH 7.27-8.92). Peduncle of petiole long and slender, downcurved in profile and with a small, dentiform anteroventral process. Subpetiolar process not followed by a cuticular crest along the mid-ventral surface of the peduncle. Petiole node in profile narrowly conical, vertical to slightly inclined anteriorly; acute apically. In posterior view the sides of the petiole node approximately parallel in their lower halves, but in their upper halves convergent dorsally to a rounded apex that is usually narrowly rounded in larger, more broadly rounded in smaller, individuals. Petiole node with faint superficial punctulate sculpture, almost effaced in some. Postpetiole in profile shallowly convex dorsally, about 1.35-1.57 times longer than high; in dorsal view distinctly longer than broad; maximum dorsal width of postpetiole ca 0.36-0.43, about equal to its height. Dorsum of postpetiole node finely punctulate and with a few weak superficial rugulae. Base of first gastral tergite usually with short but obvious basigastral costulae, effaced in smaller workers; tergite otherwise unsculptured.</p><p>Pilosity: with head in full-face view the side in front of the eye with 0-1 projecting setae, the side behind the eye with 0-3 (usually 1) projecting setae, without setae that project outward from below the eye itself; with head in profile the dorsum behind the highest point with 3-4 pairs of setae that are inclined anteriorly, followed by a transverse row of 4-6 setae closest to the posterior margin (extremely rarely this row reduced to a single widely separated pair); pronotal dorsum with a 0-2 pairs of setae, when 2 pairs present one is at the humeri, the other is very close to the mesonotal junction, a count of 0 may be the result of abrasion; mesonotum usually with 1 pair anteriorly, but rarely a second, more posterior pair present, no setae at the metanotal groove; propodeal dorsum without setae; ventral surface of metafemur with 0-1 setae, when present close to the metatrochanter; petiole node with a pair of setae on its posterior face; postpetiole with 1-2 pairs of setae dorsally and with a transverse row of 4 posteriorly; gaster with numerous simple setae. Most of the differences in pilosity are the result of normal variation, but some may be due to abrasion. Full adult colour yellowish brown to brown.</p><p>QUEEN (gyne). Ergatoid (e.g. CASENT0494286). TL 6.7, HL 1.34, HW 0.99, CI 74, SL 1.40, SI 141, WL 1.92, MfL 1.86, MfL/HW 1.88, MfL/MfH 6.64. EL 0.25 (EL/HW 0.25) (1 measured). Propodeal spine length 0.44, but the spines stouter than in the worker. Postpetiole length 0.56, width 0.59, height 0.59. Most dimensions are within the worker ranges, but the scape is relatively shorter, the metafemur is both absolutely and relatively shorter, and is somewhat deeper in posterior view. In general the ergatoid matches the worker description, but the pronotal sculpture is more sharply reticulate-rugose, and the humeral angles are more pronounced. Pilosity as worker but head without the posterior transverse row (this may have been abraded away in the single specimen available). Ocelli are absent.</p><p>MALE. (e.g. CASENT0082288) Mandible with 9-11 sharp teeth. CI 75-76, SI 45-48, MfL 1.80-1.90 (2 measured). First funicular segment of antenna less than 0.50 times the length of the second segment. EL/HW 0.44-0.45. With head in profile the dorsal outline behind the posterior ocelli slopes down gradually to the occipital carina, the surface not vertical immediately behind the ocelli. With mesosoma in dorsal view the pronotum forms a visible anterior arc in front of the mesoscutum. Notauli absent. Peduncle of petiole with spiracles borne on tubercles, in dorsal view the tubercles large and strongly prominent, the distance across them distinctly greater than the width of the node. Postpetiole in dorsal view long and narrow, 1.94-2.06 x longer than broad.</p><p>Unassociated male. Two specimens (CASENT0085227 and CASENT0085227-D01) (one badly damaged) are present in CASC (Madagascar: Prov. Antsiranana, P.N. Montaigne d’Ambre, MA-01-01D-04 (E.R. Harin’Hala)), that appear close to jugum but are specifically distinct. They contrast to the male of jugum as follows. Mandible with 8-9 sharp teeth. CI 84, SI 42, MfL 1.10. First funicular segment of antenna 0.40 times the length of the second segment. EL/HW 0.48. Peduncle of petiole with spiracles borne on tubercles, in dorsal view the tubercles large and strongly prominent, the width across them is greater than the width across the node. Postpetiole in dorsal view shorter and broader, 1.25 x longer than broad.</p><p>It is most likely that these two males represent a species whose worker remains undiscovered, but it is also possible that jugum, as presently envisaged, consists of two unrecognised siblings. A final, but much less probable, situation is that the males represent a socially parasitic form, but they show no characters attributable to the "inquiline syndrome."</p><p>Holotype worker, Madagascar: Antsiranana, Res.

The main differences between them include the profile shape of the clypeus, indentation of the cephalic dorsum, and aspects of the pilosity.</p><p>M. jugum nests in the ground and forages in the leaf litter, in rotten wood and on the surface of the ground; it has been recovered from litter samples and pitfall traps. The species also ascends low vegetation and workers have been discovered investigating Malaise traps. Most collection records are from tropical dry forest, but jugum also occurs in rainforest and littoral forest.</p><p>Non-paratypic material examined. Madagascar: Prov.

Median portion of clypeus evenly convex in profile, without a false anterior margin; median clypeal seta arises from just above midpoint of anterior margin, not from a tubercle at the midpoint of an elevated false anterior margin. Median portion of clypeus with a number of weak longitudinal rugulae which may be incomplete or broken. Scapes extremely long (SI&gt; 200), with minute pubescence but lacking standing setae. Club segments of funiculus long and slender, much longer than broad. EL 0.19-0.28 (EL/HW 0.26-0.29), with 15-16 ommatidia in the longest row. With head in full-face view sides behind the eyes elongate and strongly convergent posteriorly (width across posterior margin &lt;0.60 x HW), without an angle between side and posterior margin; posterior margin transverse, the occipital carina distinct but not produced into a raised translucent cuticular flange. Dorsum of head finely longitudinally rugose, the rugae weakening and fading posteriorly; spaces between the rugae conspicuously reticulate-punctulate. Ventral surface of head with faint, superficial transverse costulae. Dorsum of mesosoma densely reticulate-punctulate, and with minute low rugulae that are disorganised on pronotum but predominantly transverse on propodeum. In dorsal view pronotum broadest behind the humeri, but the sides behind the humeri gradually increase in width and are not abruptly flared outward. Propodeal spines long (0.54-0.64), sometimes the spine extremely broad basally, occupying all of the declivity to immediately above the propodeal lobe. Propodeal declivity unsculptured. Side of mesosoma reticulate-punctulate, with scattered feeble rugulae. Metafemur very long and slender, MfL 2.15-3.04 (MfL/HW 2.81-3.20, MfL/MfH 10.24-12.29). Peduncle of petiole long and slender, downcurved in profile and with a small, dentiform anteroventral process. Subpetiolar process not followed by a cuticular crest along the mid-ventral surface of the peduncle. Petiole node in profile bluntly conical, not inclined anteriorly. In posterior view the sides of the petiole node converge dorsally to a narrowly rounded apex in smaller workers; but in larger workers the sides are shallowly convex in their lower halves, narrower and straighter in their dorsal halves, and terminate in a small dorsal peak or tubercle on each side; dorsal surface of node between the peaks shallowly concave. Petiole node with faint superficial punctulate sculpture. Postpetiole in profile convex dorsally, about 1.30-1.47 times longer than high; in dorsal view distinctly longer than broad; maximum dorsal width of postpetiole (ca 0.35-0.50) about equal to its height. Dorsum of postpetiole node finely reticulate-punctulate and sometimes with a few vestiges of minute rugulae. Extreme base of first gastral tergite minutely punctulate, without basigastral costulae or at most with only the faintest vestiges of costulae remaining; tergite otherwise unsculptured.</p><p>Pilosity: with head in full-face view the side, both in front of and behind the eye, without projecting setae; with head in profile the dorsum behind the highest point with 1-3 pairs of setae that are inclined anteriorly, mostly grouped around highest point of vertex, without a transverse row of setae in front of the posterior margin; pronotal dorsum usually without setae, but rarely with 1 small pair, very close to the mesonotal junction; mesonotum usually without setae but extremely rarely 1 pair present anteriorly, never with setae at the metanotal groove; propodeal dorsum lacks setae; ventral surface of metafemur lacks setae; petiole node with 0-1 pair of setae on its posterior face; postpetiole usually without setae dorsally, but rarely 1 pair present, postpetiole posteriorly with 1 pair; gaster with sparse short simple setae. Full adult colour yellow to slightly orange-yellow.</p><p>QUEEN (gyne). Ergatoid. (e.g. CASENT0420020) TL 7.0-7.8, HL 1.40-1.52, HW 0.97-1.00, CI 65-69, SL 1.56-1.86, SI 161-188, WL 1.94-2.08, MfL 2.08-2.40, MfL/HW 2.14-2.42, MfL/MfH 9.33-10.90 (5 measured). EL 0.26-0.28 (EL/HW 0.26-0.28). Propodeal spine length 0.47-0.56, but the spines stouter than in the worker. Postpetiole length 0.66-0.68, width 0.68-0.70, height 0.68-0.72. Most dimensions are within the worker ranges, but the head is shorter and broader, the scape is relatively shorter, and the metafemur is both absolutely and relatively slightly shorter. In general the ergatoid matches the worker description, but the mesonotum is more strongly developed and the postpetiole and gaster are distinctly more voluminous. Pilosity appears reduced from the worker condition. Of the two ergatoid paratypes one has a single pair of setae at the highest point of the vertex, the other lacks cephalic setae; both entirely lack setae from the dorsal mesosoma, petiole and postpetiole; the first gastral tergite is naked, or has setae only at the extreme posterior margin. Non-paratypic ergatoids have 0-2 pairs of setae on the cephalic dorsum, but otherwise match the paratypes. Ocelli variably developed: all three ocelli are obvious in some of the ergatoids, but in the others, including both paratype ergatoids, only a reduced median ocellus, or an ocellar pit, remains. Field dissections of ergatoid queens from Galoko revealed that ovaries were active and there was sperm in spermatheca (C. Peeters, unpublished).</p><p>MALE. (e.g. CASENT0906626) Mandible with 8-11 sharp teeth. CI 67-70, SI 77-80, MfL 1.96-2.16 (2 measured). First funicular segment of antenna only 0.23-0.26 x the length of the second segment. EL/HW 0.49-0.50. With head in profile the dorsal outline behind the posterior ocelli slopes down gradually to the occipital carina, the surface not vertical immediately behind the ocelli. With mesosoma in dorsal view the pronotum forms a visible anterior arc in front of the mesoscutum. Notauli absent. Peduncle of petiole with spiracles borne on low prominences, in dorsal view the width across them is distinctly less than the width across the node. Postpetiole in dorsal view 1.45-1.55 x longer than broad.</p><p>Holotype worker (upper specimen of two on pin), Madagascar: Prov. Antsiranana, Nosy Be, Res. Lokobe, 6.3 km. 112° ESE Hellville, 30m., 13°25'S, 48°20'E, 19-24.iii.2001, ground nest, rainforest, BLF 3488, CASENT0427840 (Fisher et al.) (CASC).</p><p>Paratypes. 4 workers and 2 ergatoid queens with same data as holotype; one worker mounted below holotype, the others coded: 1 worker CASENT0427842; 2 workers CASENT0427889; 2 ergatoid queens CASENT0427841 (CASC, BMNH).</p><p>The worker of this species has the most attenuated scapes and femora in the genus. Its SI 201-231 and MfL/ HW 2.81-3.13 are greater than in any other species, where the collective measurements are SI 97-192, and MfL/ HW 1.25-2.76. The metafemur is extremely long and slender (MfL/MfH&gt; 10.0) when compared to the other species (MfL/MfH collectively &lt;9.0). M. sofna is also the most lightly sculptured member of the genus, with the predominant sculpture of the dorsal mesosoma of dense reticulate-punctulation, rather than sharp rugae. The head capsule is strongly narrowed posteriorly, and cephalic pilosity is reduced compared to the other species; there is no posterior transverse row of 4-6 setae close to the posterior margin.</p><p>M. sofma nests in the ground or in rotten wood, and has been found in rainforest and montane rainforest, as well as in tropical dry forest. It forages mainly on the ground and in leaf litter, but also ascends low vegetation. Nests are often associated with steep clay or stone substrate and the entrance is an ear-like turret that is sunk into a shallow alcove or raised above the rock surface (Figs 28, 29). The function of this specialized nesting behavior is not known but may be used to evade predation by other ants. The nest structure is in part similar to the clay bank nesting Stenamma in Central America (Longino, 2005; Branstetter, 2013).</p><p>Non-paratypic material examined. Madagascar: Prov.

The ergatoid lacks ocelli and mostly matches the worker description. The mesonotum is enlarged by comparison with the worker, and its margins are more stongly defined. The promesonotal suture forms a broad, shallow impression and the posterior mesonotum is defined in profile. Propodeal spiracle separated from apex of metapleural gland bulla by less than the spiracle’s diameter. Peduncle of petiole shorter and stouter than in worker. Postpetiole and gaster in dorsal view broader than in worker, as discussed under producta queen.</p><p>Diagnosis of male</p><p>Known only for M. producta . Slightly smaller than workers. Mandible triangular and strongly dentate, with 9-10 teeth. Palp formula 5,3 (in situ count). Clypeus with an anterior apron. Antenna with 12 segments, long and filiform. SI 37-44. First funicular segment short, not globular, about one third the length of the second funicular segment. In full-face view eye either located behind midlength of head capsule, or occupying most of the side. Ocelli conspicuous. Mesotibia and metatibia each with a single simple spur. Notauli very reduced or absent, at most the anterior arms discernible as extremely feeble impressions. Mesopleuron with a marked transverse sulcus. Propodeum armed with a pair of small, triangular teeth, the spiracle at about the midlength of the sclerite; propodeal lobes rounded. Petiole with an anterior peduncle, the spiracle at about the midlength of the peduncle, well in front of the level of the node. Subpetiolar process present, small. Parameres large. Cerci present. Pilosity slender, fine and dense everywhere.</p><p>Forewing venation. Rsf4-5 does not meet Rf3 on anterior margin of wing (= marginal cell open). 2rs-m absent. 1m-cu present. Fusion of Rs+M extended distally, so that 1m-cu arises from Rs+M, not from M. Rsf3 present (Rs+M divides into Rsf3 and Mf3-4 proximal of the junction with 2r-rs). Af2 long, not merely a stub distal of cu-a, the latter is retracted toward the wing base and arises from M+Cu, proximal of the point where it divides into Mf1 and Cuf1-2.</p><p>Males taken in association with workers are unknown. However, there is one male-based species (2 specimens) from Prov. Toamasina, Betampona Reserve, BLF 19594-49, CASENT0143821, and BLF 19594-55, CASENT0145230 that are linked by DNA structure to Myrmisaraka producta (B.L. Fisher, unpublished). A second male-based species (1 specimen), Prov. Toamasina, Ambodiriana, BLF 12838, CASENT0068183 is congeneric with the male of producta but apparently not linked to brevis, the other worker-based species included here.</p><p>The two different male forms are easily distinguished as one has much larger eyes than the other. M. producta: eyes larger, in full-face view the maximum length of the eye is 0.64 x HL; in profile the shortest distance from the dorsal margin of the eye to the base of the posterior ocellus is less than the vertical height of the ocellus. Second male form (Ambodiriana): eyes smaller, in full-face view the maximum length of the eye is 0.47 x HL; in profile the shortest distance from the dorsal margin of the eye to the base of the posterior ocellus is greater than the vertical height of the ocellus.</p><p>Comments on Myrmisaraka</p><p>1 In the vast majority of Myrmisaraka workers there are two setae within the notch on the anterior clypeal margin. They are short and fine, located close together, one on each side of the midpoint of the margin. Much more rarely, there is only a single seta present. In some instances the seta is off-centre and obviously indicates that its twin has fallen off and been lost. However, in a very few specimens there is a single seta that is definitely median.</p><p>The occurrence of this variation within a species is uncommon in myrmicines, having been recorded elsewhere only in a few species of Stenamma and Rogeria (Bolton, 2003; Branstetter, 2009).</p><p>2 This small genus resembles the very widespread Aphaenogaster in habitus. The following characters distinguish the two.</p><p>In Myrmisaraka a transverse crest is present on at least the mesial half of the stipes; a distinct subpetiolar process is present that appears as a sharp tooth in profile but as a transverse crest in ventral view; the propodeal spiracle is large and relatively low on the side, closer to the apex of the metapleural gland than to the dorsal outline; the postpetiole is elongate, dorsoventrally flattened in profile and very broad in dorsal view; the sting is strongly developed and conspicuous. In addition, the pair of setae that straddle the midpoint of the anterior clypeal margin are short, very fine, and are closely approximated basally. Finally, the ventral metathorax has a posteriorly divergent pair of carinae, that arise just anterior of the metasternal pit, diverge posteriorly, and terminate at the inner margins of the metacoxal annuli.</p><p>The corresponding states in Aphaenogaster are: a transverse crest is usually absent from the stipes (weaky visible in a few species, strong only in A. relicta Wheeler &amp; Mann, from Haiti, which may not be properly referable to this genus); subpetiolar process is absent; propodeal spiracle is small and relatively high on the side, usually closer to the dorsal outline than to the apex of the metapleural gland; postpetiole is not elongate nor dorsoventrally flattened in profile (usually strongly convex and dome-like), and is not broad in dorsal view; the sting is extremely weakly developed and usually invisible. In addition, the pair of setae that straddle the midpoint of the anterior clypeal margin are long and stout, markedly separated basally. The ventral metathorax does not show a divergent pair of carinae such as are described above. The validity of this final observation needs confirmation as the number of Aphaenogaster species examined is small, but does include the Madagascan A. swammerdami Forel .</p><p>The Malagasy fauna includes three Aphaenogaster species, all confined to Madagascar itself, A. friederichsi Forel, A. gonacantha (Emery) and A. swammerdami Forel . The second and third of these belong to the old subgenus A. (Deromyrma), principally characterised by the extension of the posterior portion of the head into a long, narrow, constricted neck. Because of this striking development these two species can not be confused with Myrmisaraka . A. friederichsi does not exhibit this modification, but differs from Myrmisaraka in all the characters mentioned above.</p><p>Synopsis of Myrmisaraka species</p><p>brevis Bolton &amp; Fisher sp. n.</p><p>producta Bolton &amp; Fisher sp. n.</p><p>Key to Myrmisaraka species (workers)</p><p>1 Antenna terminates in a distinct club of three segments (Fig. 30).

Pair of setae that straddle midpoint of anterior clypeal margin short and fine, closely approximated, arising within the small concave median notch in the anterior clypeal margin; infrequently only a single seta present. Median portion of clypeus with a series of 4-6 longitudinal rugulae, the median obsolete or obliterated. Eyes large and strongly convex, dome-like, very obviously interrupting the outline of the side in full-face view, EL 0.24-0.30 (EL/HW 0.31-0.35). With head in full-face view the sides shallowly convex, converging posteriorly behind the eyes, the posterior corners broadly rounded and the posterior margin shallowly convex. Occipital carina strongly developed and extends for a short distance onto ventral surface of head, then rapidly peters out just in front of the posteroventral angle. Scapes long (SI 115 or more) with elevated pubescence and a number of short, fine curved setae that are suberect to subdecumbent and inclined toward the scape apex. Antenna with a 4- or 5- segmented club. The 4-segmented club is achieved by the elongation of funiculus segment 8, so that it is 1.55-1.75 x longer than broad. This elongation of funiculus segment 8 brings its length closer to that of segment 9, so that funiculus segment 9 is only 1.00-1.20 x longer than segment 8. In some workers (and in the ergatoid) funiculus segment 7 is also somewhat elongated, so that the club appears weakly 5- segmented. Sides and dorsum of head with numerous fine setae. Head predominantly irregularly longitudinally rugulose, with some cross-meshes, especially posteriorly; spaces between rugulae with feeble ground sculpture of superficial punctulae. Pronotum without an anterior transverse carina; promesonotal dorsum irregularly rugose and the sculpture more strongly expressed than on the head; propodeal dorsum irregularly rugose. In profile, sides of pronotum, metanotum and propodeum reticulate-rugulose, but on mesopleuron the rugulae somewhat stronger and predominantly longitudinal. Propodeal spines long (ca 0.35-0.36), slender and acute, distinctly longer than their basal width in profile; in dorsal view weakly divergent posteriorly. Legs relatively long and slender, MfL&gt; 1.00. All femora and tibiae with outstanding fine setae on all surfaces. Subpetiolar process appears as a small tooth in profile, but in posterior view is seen as a transverse ridge. Peduncle of petiole in profile longer than the node, the latter evenly rounded dorsally. In dorsal view the postpetiole slightly broader than long and broader than the petiole node; postpetiole sides convex and divergent for more than three-quarters of their length, then convergent posteriorly. Sternite of postpetiole distinctly broader posteriorly than anteriorly. Sides and dorsum of petiole and postpetiole very weakly rugulose, but the sculpture almost effaced on the posterior surface of the petiole. First gastral tegite unsculptured. Dorsal surfaces of mesosoma, petiole, postpetiole and first gastral tergite with numerous fine, simple setae; those on the propodeal dorsum confined to the posterior half of its length. Full adult colour uniform yellow to light brown.</p><p>QUEEN (gyne). Ergatoid (CASENT0495050, BLF 8146, data below (CASC)). TL 5.2, HL 1.01, HW 0.81, CI 80, SL 0.98, SI 121, PW 0.61, WL 1.34, MfL 1.22 (1 measured). Eyes slightly larger than in worker, EL 0.30 (EL/ HW 0.36); ocelli absent. Anterior clypeal margin medially has only a single seta, but this is off-centre and implies that one seta (the left) has been lost from an original pair. As in some workers funiculus segment 7 is lengthened, so that the club is weakly 5-segmented. Mesonotum enlarged and its margins more stongly defined. Promesonotal suture a broad, shallow impression and the posterior mesonotum defined in profile. Postpetiole and gaster in dorsal view distinctly broader than in worker. Maximum width of postpetiole in dorsal view 0.44-0.52 in worker, 0.65 in ergatoid; of gaster in dorsal view 0.78-0.93 in worker, 1.34 in ergatoid.</p><p>A single specimen out of 9 in series BLF 13148 (data below) also appears to represent an ergatoid, but it is not nearly so conspicuous as the one just discussed. Its mesosoma and waist segments are more like the ergatoid form than that of the workers, and the width of its postpetiole (0.54) and gaster (1.10), while much broader than in workers of the same series (0.44-0.50 and 0.85-0.93, respectively), are less than those of ergatoid BLF 8146 (0.65 and 1.34, respectively). Strangely, the head, scape and metafemur of this probable ergatoid are shorter than in the measured workers from the same series, with HL 0.99 (HL 1.02-1.09 in workers), HW 0.80 (HW 0.82-0.85 in workers), SL 0.91, SI 114 (SL 1.04-1.10 and SI 126-129 in workers), MfL 1.12 (MfL 1.26-1.30 in workers). It therefore seems that a range of morphological variation, between obvious worker and obvious ergatoid, is probable.</p><p>Holotype worker, Madagascar: Prov.

In one notorthotenes queen a stub of lm-cu is present on the left wing, but not on the right; in another queen a stub occurs on the right wing but not on the left; entirely absent in all other alate material. Af2 not merely a stub distal of cu-a, the latter retracted toward the wing base and arises from M+Cu, proximal of the point where M+Cu divides into Mfl and Cufl-2.</p><p>Comments on Royidris</p><p>The 15 endemic Madagascan species included in this genus exhibit a habitus that is convergent on some groups of Monomorium . In his study of the Afrotropical members of that genus Bolton (1987: 290) noted two indeterminate Madagascan species which had a high palp formula (5,3), the highest attributed to Monomorium, but did no further analysis of these odd species because the focus of the survey was the extensive Afrotropical fauna. Heterick (2006), in his revision of the Malagasy species of Monomorium, recognised the peculiarity of the high palp formula and utilised it, together with some other characters, to define his M. shuckardi group, all members of which are now transferred to Royidris .</p><p>At present, no unambiguous apomorphy can be stated for Royidris, and in fact its habitus is similar to that commonly seen in Monomorium . However, a note of caution must be introduced, because no apomorphies can be cited for Monomorium in its currently accepted form, and it is becoming increasingly obvious that it is polyphyletic. A full survey of its present components, with more detailed morphological and molecular analyses, will be essential if the unwieldy Monomorium is ever to be divided into meaningful monophyletic units that can be awarded generic status. For the present, therefore, members of Royidris can be separated from Monomorium by the presence in Royidris of all the seven following characters in combination: palp formula 5,3; mandible with 5 teeth; antenna 12-segmented, with a club of 3 or 4 segments; propodeal spiracle in profile close to dorsal surface of propodeum; propodeal dorsum usually without setae (one or more pairs of short setae may be present in two species); petiolar spiracle close to midlength of peduncle (not at the node); first gastral tergite does not strongly overlap the sternite on the ventral surface of the gaster.</p><p>In Madagascar, and also in Africa, only one Monomorium species, the tramp M. latinode Mayr, has 5 mandibular teeth. However, M. latinode has a palp formula of 3,3, unsculptured mandibles, the eye situated conspicuously far in front of the midlength of the head capsule, the propodeal dorsum transversely costulate and with numerous setae present, the petiolar spiracle at the node, and a first gastral tergite that strongly overlaps the sternite ventrally.</p><p>Species groups of Royidris</p><p>Three groups of species can be isolated on worker morphological grounds within the genus. The groups are currently defined for convenience and ease of identification, and do not necessarily reflect accurate phylogeny.</p><p>1 The admixta group ( admixta, depilosa). Antennal club of 3 segments (Figs 36, 47). Promesonotum not swollen or domed: in profile the dorsum flat or nearly so, evenly sloping posteriorly to the metanotal groove. Propodeal dorsum behind the metanotal groove approximately continues the line of the promesonotal outline; the propodeal dorsum is not considerably depressed below the level of the promesonotum (Figs 36, 45). Scapes and metafemora in the group are among the shortest in the genus (SI 90-95, MfL/HW 0.90-0.95), and the postpetiole is the broadest (maximum dorsal width 0.42-0.48 x HW). In all other species combined, these measurements show ranges of SI 90-158 (SI &lt;100 only in some workers of gravipuncta and clarinodis), MfL/HW 0.95-1.50 (again, MfL/HW &lt;1.00 only in some workers of gravipuncta and clarinodis), maximum dorsal width of postpetiole 0.27-0.39 x HW (outside the admixta group 0.39 x HW is achieved only in longiseta).</p><p>The two species included here form a closely related pair, separated by differences in sculpture and pilosity. Both were inexplicably included as conspecific with clarinodis by Heterick (2006), whose description obviously included elements of several species that are recognised as separate here.</p><p>2 The robertsoni group ( anxietas, clarinodis, pallida, pulchra, robertsoni). Antennal club of 3 segments (Figs 39, 42, 63, 69, 72). Promesonotum swollen or domed: in profile the dorsum convex and appearing swollen, the posterior outline of the mesonotum descends steeply, and usually abruptly, to the metanotal groove (or the junction with the propodeum in those species where the groove is suppressed). Propodeal dorsum behind the metanotal groove horizontal or sloping, decidedly not continuing the line of the promesonotal outline; the propodeal dorsum is strikingly depressed below the level of the promesonotal dorsum (Figs 39, 42, 63, 69, 72). The scape is generally shorter in this group (SI 90-110) than in the notorthotenes group (SI 95-158). In the robertsoni group the only workers with SI &lt;95 are some individuals of clarinodis, while in the notorthotenes group only some individuals of gravipuncta have SI &lt;100.</p><p>Together with the two species now placed in the admixta group, four of the five names included in this group were regarded as conspecific with clarinodis by Heterick (2006); only robertsoni was treated by him as a species separate from clarinodis . The group falls into two uneven complexes of species depending on whether the metanotal groove is conspicuously retained and the eyes are obviously in front of the midlength of the side of the head capsule ( clarinodis), or the metanotal groove is suppressed and the eyes are at, or very close to, the midlength ( anxietas, pallida, pulchra, robertsoni).</p><p>3 The notorthotenes group ( diminuta, etiolata, gravipuncta, longiseta, notorthotenes, peregrina, shuckardi, singularis). Antennal club of 4 segments (Figs 51, 57, 62, 66). Promesonotum domed: in profile the dorsum convex and appearing swollen, the posterior outline of the mesonotum descends steeply, and usually abruptly, to the metanotal groove. Propodeal dorsum behind the metanotal groove horizontal or nearly so, decidedly not continuing the line of the promesonotal outline; the propodeal dorsum is strikingly depressed below the level of the promesonotal dorsum (Figs 48, 51, 54, 57, 60, 66, 78).</p><p>Both of the species that Heterick (2006) recognised, notorthotenes and shuckardi, are now considered to be compound, with diminuta and etiolata being split from his concept of notorthotenes, and longiseta and gravipuncta split from his concept of shuckardi . The two final species, singularis and peregrina, had not been discovered at the time of his study. Three complexes of species can be identified within the group. The first complex includes longiseta, gravipuncta and peregrina, and is characterised by denser, heavier cephalic sculpture, darker colour, relatively shorter scapes (SI 95-117), head that averages relatively broader (CI 82-89), and shorter metafemora</p><p>(MfL/HW 0.95-1.13). The second complex, which consists of diminuta, etiolata and notorthotenes, has cephalic sculpture that is weak to vestigial, uniform yellow in colour, relatively longer scapes (SI 115-158), head that averages relatively narrower (CI 75-84), and longer metafemora (MfL/HW 1.25-1.50). The final complex, which contains only singularis, exhibits a mixture of the features of the other two complexes. Its sculpture is largely suppressed (the head and dorsal pronotum are glassy smooth), its scapes are long (SI 121), and its body is darkly coloured; it has MfL/HW 1.13, at the top end of the range of the gravipuncta complex but well below that of notorthotenes and its relatives. R. shuckardi cannot be placed in any complex as it is known only from a single queen, but its 4-segmented antennal club indicates its placement within this species group.</p><p>Synopsis of Royidris species</p><p>admixta group</p><p>admixta Bolton &amp; Fisher sp. n.</p><p>depilosa Bolton &amp; Fisher sp. n.</p><p>robertsoni group</p><p>anxietas Bolton &amp; Fisher sp. n.</p><p>clarinodis (Heterick, 2006) comb. n.</p><p>pallida Bolton &amp; Fisher sp. n.</p><p>pulchra Bolton &amp; Fisher sp. n.</p><p>robertsoni (Heterick, 2006) comb. n.</p><p>notorthotenes group</p><p>diminuta Bolton &amp; Fisher sp. n.</p><p>etiolata Bolton &amp; Fisher sp. n.</p><p>gravipuncta Bolton &amp; Fisher sp. n.</p><p>longiseta Bolton &amp; Fisher sp. n.</p><p>notorthotenes (Heterick, 2006) comb. n.</p><p>peregrina Bolton &amp; Fisher sp. n.</p><p>shuckardi (Forel, 1895) comb. n.</p><p>singularis Bolton &amp; Fisher sp. n.</p><p>Key to Royidris species (workers)</p><p>( R. shuckardi is excluded as only its queen is known.)</p><p>1 Antennal club of 4 segments (Figs 51, 57, 60, 62, 66): in general, funiculus segments 8 and 9 appear very similar in length and volume.

Mandible longitudinally costulate. Scapes of relatively moderate length (SI 100-110); when laid straight back in full-face view the apex of the scape slightly exceeds the posterior margin of the head. With head in full-face view the eyes very close to the midlength of the side of the head capsule. EL 0.14-0.16 (EL/HW 0.29-0.31). Dorsum of head from level of eyes to posterior margin superficially but distinctly reticulate-punctulate. This sculpture tends to fade in density and intensity dorsolaterally, where it often appears merely shagreenate. Promesonotum in profile convex and swollen, domed, the mesonotum posteriorly descends abruptly to the commencement of the propodeum; the metanotal groove is absent. In absolute profile the propodeal dorsum, from its junction with the mesonotum, is flat to extremely shallowly convex; posteriorly it meets the declivity in a blunt angle and the declivity is straight and almost vertical. The whole propodeal dorsum is strongly depressed with respect to the highest point of the promesonotum, which is on a considerably higher level. All specimens appear to show some abrasion, but the maximum seta count would seem to be: pronotum with 2 (or possibly 3) pairs; mesonotum with 2 pairs; dorsum of propodeum with a single short pair, immediately above the propodeal angle (see discussion below); petiole node with 2 pairs, one apical, the other on the posterior face; postpetiole with setae dorsally and posteriorly; first gastral tergite with numerous suberect setae that are shorter than the maximum vertical diameter of the eye. Pronotal dorsum mostly smooth but with vestiges of superficial punctulate sculpture; propodeal dorsum finely reticulate-punctulate, much more strongly sculptured than the pronotum.

Fisher et al.) (CASC).</p><p>After robertsoni, this species has the second most densely sculptured head in the robertsoni group. It is easily separated from robertsoni by the unique shape of the propodeum in that species, its lack of propodeal setae, and its uniform light colour. R. anxietas, like pallida and pulchra, lacks the V-shaped, incised metanotal groove characteristic of clarinodis, but in pallida and pulchra the head is smooth. Within the group, robertsoni and clarinodis together have the metafemora relatively shorter and more incrassate, combined MfL/HW 0.93-1.09, and MfL/MfH 3.67-4.50. R. anxietas, pallida and pulchra have the metafemora relatively longer and more slender, with combined MfL/HW 1.12-1.32, and MfL/MfH 5.50-6.00.</p><p>The holotype, one paratype, and one of the three non-paratypic specimens have a conspicuous, short, erect seta on the propodeal dorsum, just anterior to the propodeal angle. The other paratype, and the other two non-paratypic specimens, lack this seta. It is assumed here that the presence of this seta is normal and that its absence represents loss by abrasion. As only six specimens are presently available this is merely a guess; the acquisition of more material is necessary to tell if the guess is accurate, or if the presence or absence of this seta is normal variation within the species. The possibility that the six specimens available may represent two species must also be considered. The three that constitute the type-series are bicoloured, with the mesosoma distinctly lighter than the gaster, while the three non-paratypic specimens are uniformly dark. By itself, colour alone would not be convincing, but the dark form also has a more weakly sculptured head. The significance of these differences cannot be assessed at present, the resolution of the problem must await future investigation when more material of both forms has accumulated. The two specimens from Ambovo Springs were included as part of clarinodis by Heterick (2006).</p><p>Most individuals of anxietas have been collected in dry forest edges and burned savannah, but samples have also been retrieved from pitfall traps in uapaca woodland, and once from an urban garden.</p><p>Non-paratypic material examined.

Heterick (2006: 89) specifically restricted the clarinodis type-series to those specimens with the same data as the holotype, i.e. the series numbered BLF 5528 and with the locality data given above. However, in CASC there is at least one specimen, name-tagged and labelled as a paratype by Heterick, which has been partially mislabelled and wrongly included in the type-series. The upper data label on the pin of this specimen gives BLF 5528, but the lower (main) data label has BLF 5504 (Prov. Toliara, Res.

Mandible smooth, unsculptured except for scattered small pits; in a few workers minute striolae may occur near the extreme base, but if present these do not extend onto the apical half of the mandible. Scapes relatively short (SI 100 or less); when laid straight back in full-face view the apex of the scape just reaches the posterior margin of the head. With head in full-face view the eyes in front of the midlength of the side of the head capsule. EL 0.09-0.12 (EL/HW 0.22-0.26). Dorsum of head from level of eyes to posterior margin smooth, with scattered minute pits; in some individuals there are also very weak vestiges (often almost entirely effaced) of superficial microreticulation. Promesonotum in profile convex and swollen, the mesonotum posteriorly descending to the distinctly impressed metanotal groove, which is V-shaped to narrowly U-shaped. Propodeal dorsum slopes posteriorly and is strongly depressed, the entire dorsum on a considerably lower level than the highest point of the promesonotum. Dorsa of pronotum and mesonotum usually each with 2 pairs of setae (sometimes with only one pair on one or the other, but this may be due to abrasion); dorsum of propodeum lacks setae. Pronotal dorsum smooth and shining, with widely scattered minute punctulae. Mesonotum as pronotum but some extremely weak vestiges of superficial microreticulation may be present. Propodeal dorsum microreticulate to reticulate-punctulate, the sculpture weak and superficial but usually stronger than on the promesonotum. Mesopleuron and metapleuron weakly reticulate-punctulate, the sculpture extending anteriorly onto the side of the pronotum as microreticulation. Metafemur relatively short, MfL 0.38-0.48 (MfL/HW 0.93-1.04, MfL/MfH 3.67-4.00). Petiole with a pair of setae on the posterior face of the node; postpetiole with 1-2 pairs of setae posteriorly; first gastral tergite with scattered short setae. Postpetiole relatively narrow in dorsal view, maximum width 0.14-0.19 (0.35-0.38 x HW). Dorsum of postpetiole and first gastral tergite unsculptured. Colour varies from mid-brown with a dark gaster, to entirely dark brown.</p><p>QUEEN and MALE: unknown.</p><p>Within the robertsoni group, as defined above, clarinodis is immediately isolated as it is the only species to combine an unsculptured head capsule with a sharply impressed, V-shaped, metanotal groove.</p><p>In Heterick’s (2006) treatment of what was then the shuckardi group of Monomorium, clarinodis was regarded as a single species that from its description was extremely variable. In the present analysis we conclude that his taxon is certainly compound, and actually contains six separate species from two species groups (admixta and depilosa of the admixta group; anxietas, clarinodis, pallida and pulchra of the robertsoni group); the original description of clarinodis includes morphological elements of almost all of them. This confusion is inexplicable as members of the admixta group have a strikingly different mesosomal configuration from the rest of the genus, and within the robertsoni group only clarinodis has a sharply incised metanotal groove.</p><p>R. clarinodis is found in spiny forest, shrubland and uapaca woodland, where it nests under stones, but it has also been collected from litter samples, as ground foragers, and from pitfall traps.</p><p>Material examined.

The main mass of this material is now regarded as gravipuncta, but a couple of specimens have much longer and denser setae and have been removed to a separate species, longiseta . An isolated queen, the only specimen that genuinely represents shuckardi, can not be associated with either of these worker-based taxa for reasons discussed under shuckardi .</p><p>R. gravipuncta is the most evenly, densely sculptured species in the genus. The entire dorsal head, and the whole mesosoma, dorsally and laterally, are strongly reticulate-punctate; the density and intensity of the sculpture is consistent on all these surfaces.</p><p>The most obvious difference between gravipuncta and longiseta concerns the setae of the promesonotum and first gastral tergite. In gravipuncta the setae are distinctly shorter than the maximum vertical diameter of the eye, whereas in longiseta they are obviously longer than the vertical diameter of the eye. In addition, the available specimens of longiseta have erect short setae on the propodeum, tend to be somewhat smaller (HW 0.54-0.56), and the sculpture is not as intense or consistently dense as in gravipuncta .</p><p>The relationship of gravipuncta to peregrina is very close. The latter appears as a much less densely sculptured version of the former, which also has relatively longer scapes and metatibiae. Unfortunately, the clarity of this division is blurred by four workers from Beanka. Among all the material retrieved from that locality, these four specimens have measurements that are within the gravipuncta range (SI 103-107, MfL/HW 1.00-1.06), but exhibit sculpture that is strikingly less dense and uniform than that shown in all other gravipuncta material. Their sculpture is however, stronger than is seen in peregrina, and microreticulation is retained on the first gastral tergite. For the present, these specimens are tentatively referred to gravipuncta, but the possibility that they constitute a separate species, or may indicate that gravipuncta and peregrina should really be regarded as a single, very variable species, must await later analysis, when more material of possible intermediate forms has become available.</p><p>This species has been collected in an urban garden, but is usually found in spiny forest, where it has been collected from under stones, as ground foragers, from pitfall traps, and from dead twigs on the ground. It may also be found in savannah shrubland and in Bismarckia woodland. The type-series was retrieved from a light trap in spiny forest, indicating that it forages by night as well as by day, and that it ascends objects that rise from the forest floor.</p><p>Non-paratypic material examined.

Among the few known queens of the gravipuncta complex, shuckardi is isolated because with its head in full-face view the eyes are located in front of the midlength of the sides, and the sides behind the eyes appear long and shallowly convex, convergent posteriorly through long, shallow curves, and with the posterior margin short and indented medially. In the worker-associated queen of peregrina, and the two unassociated queens that are known in the complex, the eyes are at, or very close to, the midlength, and the sides behind the eyes round through narrow curves into a broad posterior margin that is shallowly concave across its width.</p><p>WORKER and MALE: unknown.</p><p>This species is known only from the holotype queen. While it certainly belongs in Royidris, and because of its 4-segmented antennal club is referable to the notorthotenes group, it can not be matched with any other queen assigned to that group. In addition, as pointed out by Heterick (2006), its type-locality, Moramanga, is in Toamasina Province, hundreds of kilometers away from the range of, and with vegetation and conditions very different from, that inhabited by other species now in Royidris .</p><p>Heterick (2006) associated the isolated shuckardi holotype queen with workers of what is now considered a complex of three worker-based species, gravipuncta, longiseta, and the more recently discovered peregrina . He grouped the first two species together with the isolated queen, and regarded them as a single species, to which he applied the name shuckardi . However, there is no evidence for this association. None of the few queens associated with, or assumed to belong to the same group as the three worker-based species, corresponds to the holotype of shuckardi . Heterick (2006) suggests that the locality given for the shuckardi queen may be in error. This could be correct, but even if true the queen can not be linked to any known species. Resolution of the identity of shuckardi will require the acquisition and comparison of more samples of worker-associated queens.</p></div>	https://treatment.plazi.org/id/6DEBF1209DC6A4D6807E5E9965600BC7	Public Domain	No known copyright restrictions apply.

Gaster unsculptured.</p><p>Diagnosis of queen (gyne)</p><p>Queens are known for all species except obscura. Characters are as in the worker, except for the usual developments of the mesosoma seen in alates. The queens may be alate or ergatoid, or both forms may occur within a single species (see Table 4). It is possible that all species will be found to produce both ergatoids and alates when the species are better represented in collections. Two species ( manifesta, suspicax) exhibit morphological intermediates between alate and ergatoid forms, and two species ( acclivitas and crebra) appear to be polygynous. The alate queen has three distinct ommatidia and a characteristically large mesosoma with a full complement of flight sclerites; the pronotum is well represented on the dorsal mesosoma, and the mesopleuron has a strong transverse sulcus. Ergatoids have a mesosoma that is usually larger than in true workers but much smaller than in alates. The mesonotum is frequently hypertrophied in ergatoids with respect to the worker caste, and 1-3 ommatidia are usually present, although only a vestigial median ocellus may be remain; there is no transverse sulcus on the mesopleuron. Intermediates between these two extremes exhibit a mesosoma that is alate-like but much smaller in size, usually with most or all sclerites of the pterothorax represented but in a reduced form, fused together, and with no trace of wing attachments; 3 ocelli are always present in these forms. Venation: see under male.</p><p>Diagnosis of male</p><p>Worker-associated males are known for crebra, breviscapa and labes . In addition, the males of three other species, collected in isolation (in Malaise traps), are present in CASC. Similar in size to the conspecific worker or slightly smaller. Mandible triangular and distinctly dentate, with 5-7 teeth. Palp formula 5,3 (in situ counts). Stipital crest present on maxilla. SI 30-52. Antenna with 13 segments, conspicuously not filiform, characteristically modified. First funicular segment short but not globular, about 0.40-0.60 x the length of the second funicular segment. Funiculus segment 8 (= antennal segment 9) about equal in length to the scape. Funiculus segment 9 (= antennal segment 10) strikingly elongate, 1.45-1.80 x SL, and the funiculus with a kink or angle between the elongate ninth segment and the tenth. The three apical funicular segments (10-12) are also elongate and form a slender club, of which at least the apical segment is longer than SL (sometimes 2 or all 3 apical segments are&gt; SL). Eyes large, located at or in front of the midlength of the sides. Ocelli conspicuous. Occipital carina sharp but not forming a raised crest. Mesoscutum in profile strongly overhangs the pronotum, the latter not visible in dorsal view. Mesotibia and metatibia each with a single, simple spur. Notauli variably developed, from vestigial to having anterior arms present. Mesopleuron with a transverse sulcus present. Propodeum usually unarmed and rounded, but in some the posterodorsal angle is reinforced by a carina, or the angle projects as a low, obtuse tooth; propodeal lobes rounded. Petiole in profile slightly longer than postpetiole. Petiole with an anterior peduncle, the spiracle at, or slightly in front of, the midlength of the peduncle, well in front of the level of the low, rounded node. Subpetiolar process minute to absent.

They obviously represent a very compact single group. Unfortunately, Vitsika workers are currently diagnosed among the myrmicines only by the presence of a unique combination of characters. As with many other myrmicine genera no unique morphological apomorphy can yet be cited. It is defined by its possession of the following characters in combination: mandible with 6 or more teeth; palp formula 5,3; stipital crest strongly present; antenna 12-segmented, with a 3-segmented club; clypeus with an isolated median seta set above a narrow anterior apron; clypeus posteriorly narrowly inserted between the frontal lobes; frontal carinae present and long, extending almost to the posterior margin of the head; antennal scrobes present; mesosomal dorsal outline simple; petiole pedunculate; first gastral tergite does not overlap the sternite on the ventral surface of the gaster; gastral shoulders absent.</p><p>Synopsis of Vitsika species</p><p>acclivitas Bolton &amp; Fisher sp. n.</p><p>astuta Bolton &amp; Fisher sp. n.</p><p>breviscapa Bolton &amp; Fisher sp. n.</p><p>crebra Bolton &amp; Fisher sp. n.</p><p>disjuncta Bolton &amp; Fisher sp. n.</p><p>incisura Bolton &amp; Fisher sp. n.</p><p>labes Bolton &amp; Fisher sp. n.</p><p>manifesta Bolton &amp; Fisher sp. n.</p><p>miranda Bolton &amp; Fisher sp. n.</p><p>obscura Bolton &amp; Fisher sp. n.</p><p>procera Bolton &amp; Fisher sp. n.</p><p>suspicax Bolton &amp; Fisher sp. n.</p><p>tenuis Bolton &amp; Fisher sp. n.</p><p>venustas Bolton &amp; Fisher sp. n.</p><p>Key to Vitsika species (workers)</p><p>Note.

Propodeum unarmed; propodeal dorsum unsculptured; propodeal dorsum and declivity without trace of a median longitudinal carina. Postpetiole in dorsal view longer than broad. Dorsal arc of eye, from midpoint of anterior margin to midpoint of posterior margin, bounded by a marked impression in the cuticle of the head capsule. Scape only very slightly longer than funiculus segment 2 (antennal segment 3); scape about equal in length to funiculus segment 8; funiculus segment 9 easily the longest antennal segment (ca 0.24); funiculus segments 10 and 11 each about equal in length to the scape; apical antennal segment (funiculus segment 12) almost 2 x SL. Colour dull yellow, with infuscated patches, especially dorsum of head around the ocelli.</p><p>Holotype worker (top specimen of 3 on pin), Madagascar: Prov. Toamasina, Mont.

(CASC).</p><p>Paratypes. 2 workers mounted on pin below holotype; 2 workers with same data but CASENT0496231 (CASC).</p><p>The immediate distinguishing features of breviscapa workers are the combination of yellow colour, relatively short scapes (the shortest in the genus), metafemur that is always shorter than HW, and propodeal spines that are shorter than in all other species except crebra . Confusion with crebra should be impossible as the postpetiole in crebra is entirely densely sculptured, its postpetiole in dorsal view is 1.35-1.45 x broader than long, and its SI is 85-91. In addition, in crebra, the anterior curvature of the outline of the eye in profile is very similar to the posterior curvature, whereas in breviscapa the eye is more obviously tear-drop shaped, with an outline that is much more narrowly rounded and pointed anteriorly than posteriorly.</p><p>A few specimens of breviscapa have been recovered from leaf litter samples in rainforest, but the great majority were captured in association with plants of the family Melastomataceae. The biology of the ant-plant association is not known, but breviscapa appears to be the only known member of Vitsika that is plant-associated.</p><p>Non-paratypic material examined. Madagascar: Prov.

The shape of the petiole node in profile shows some variation, the significance of which is not immediately apparent. In some specimens of procera the bluntly rounded anterodorsal angle of the node is the highest point in profile. The dorsal surface is only shallowly convex, and slopes downward posteriorly from the anterodorsal angle; the dorsum then meets a differentiated short posterior face through a blunt and rounded angle (e.g. procera type-series). However, in others the dorsum is shorter, distinctly more strongly convex, and rounds much more broadly into the posterior face, to such an extent that in some the two faces are not differentiated. The significance of this variation cannot be estimated at present, but two possibilities present themselves: first, that more than one sibling species currently resides under the name procera; second, that procera specimens are really nothing more than isolated strongly sculptured examples of suspicax . Nest series of a decent size, of both nominal forms, will be necessary before these alternatives can be resolved.</p><p>All material was retrieved from litter samples in rainforest, except for a single worker, which was acquired by beating low vegetation in rainforest.</p><p>Non-paratypic material examined.

Petiole node in profile more or less erect with respect to the peduncle, the node not obviously inclined posteriorly; node usually without a defined posterior surface that is distinctly differentiated from the dorsum. In general the ascending anterior face of the node terminates in a blunted anterodorsal angle, which is the highest point of the node.

[Note that two workers, with same data as holotype but BLF 9242(8), CASENT0040786 (head missing) and CASENT0040787 (head, waist segments and gaster missing), are omitted from the type-series as they are badly damaged.]</p><p>Separated only weakly from procera by the form and sculpture of the petiole node, which in suspicax is more slender and generally less angular in profile, with a broader and more shallowly convex dorsal margin in posterior view, and always more feebly and superficially sculptured. As mentioned under procera, it may transpire that suspicax and procera are respectively less and more strongly sculptured variants of a single species. A single worker from Ankarana (CASENT0275352), may represent a very closely related but separate species. This specimen is at the top end of the size range given above (HL 0.72, HW 0.60, SL 0.52, MfL 0.64), but has a higher and more slender petiole node than is usual, more strongly developed rugose sculpture on the mesosoma, and a metanotal groove that in profile is broader and more obviously concave. We consider this specimen as suspicax until more material indicates otherwise.</p><p>All material was retrieved from litter samples or from yellow pan traps, in montane rainforest.</p><p>Non-paratypic material examined.

MfL 0.45-0.52 (MfL/HW 0.98-1.00). Dorsal outline of propodeum in profile, from approximate site of metanotal groove to dorsal base of spine, evenly curved or at most with a very low, obtuse angle anteriorly. Propodeal spines in profile usually distinctly downcurved along their length. Degree of curvature of the spines is variable: in most it is striking but in a few it is not as pronounced, and in the very smallest workers it may not be apparent. Diameter of annulus of propodeal spiracle is about equal to the thickness of the propodeal spine at its midlength. Petiole node in profile small, more or less erect with respect to the peduncle, the node not obviously inclined posteriorly; narrowly but bluntly rounded dorsally, and with the anterior and posterior faces converging toward the dorsum. Sculpture of petiole node faint to vestigial laterally, absent from posterior surface. Height of petiole node in posterior view (from midpoint of the dorsal margin of the foramen to the apex) 0.86-0.95 x its maximum width. In dorsal view postpetiole 1.20-1.38 x broader than long; maximum width of postpetiole 0.93-1.15 x the length of a propodeal spine; maximum width of postpetiole 0.82-0.92 x the distance between the apices of the propodeal spines.

In reality, the size ranges of the two form a rough continuum, with the upper limits for venustas constituting the lower limits for labes, which raises the possibility that labes is merely a larger morphotype of venustas . Contradicting this possibility is the fact that specimens of both forms have never been retrieved from a single sample, and some series of venustas are extensive. Consequently, the two are regarded as separate species here.</p><p>Most examples of venustas were retrieved from leaf litter samples in rainforest, but a few have been found in pitfall traps and yellow pan traps, and a colony was discovered in a dead twig on the ground.</p><p>Non-paratypic material examined.
