Helioserica Ahrens, Lukic &amp; Liu, new subgenus</p><p>Type species of the new subgenus: Microserica varians Moser, 1915 (by current designation).</p><p>Diagnosis. The new subgenus differs from its sister clade (Fig. 1), Gastroserica sensu stricto, by the well-produced and distinctly angled anterior angles of pronotum, as well as by the distinctly emarginated anterior margin of labroclypeus. Furthermore, the apical abdomen is not as robustly developed as in most Gastroserica sensu stricto species, with the pygidium barely protruding under the apex of elytra.</p><p>Remarks. Given, of being the sister lineage of Gastroserica (Fig. 1; see also Eberle et al. 2017), and thus representing a monophyletic group with the species of Gastroserica sensu stricto, we nevertheless decided to erect a new and separate subgenus for these species, since key diagnostic features of Gastroserica sensu stricto are not present among these species, namely the obsolete anterior angles of pronotum and the straight, non-emarginate anterior margin of labroclypeus.</p><p>All species so far classified as Gastroserica (Ahrens &amp; Bezděk 2016) are subsequently assigned to the subgenus Gastroserica Brenske, 1897 .</p><p>Etymology. The name of the new subgenus is composed of the Greek word “ helios ” (sun) and the word root Serica (type genus of the tribe Sericini), with reference to the diurnal activity of the species of this subgenus.</p><p>Key to the species of the Gastroserica ( Helioserica new subgenus) (♁♁):</p><p>1 Dorsal surface mostly dull or iridescent.................................................................... 2</p><p>- Dorsal surface completely simply shiny................................................................... 14</p><p>2 Elytra with multiple dark spots and darker striae..........................................

Frons dull, with sparse, coarse punctures, beside eyes and behind frontoclypeal suture with a few single short setae, otherwise with minute setae in punctures. Smooth area in front of eyes twice as wide as long. Ocular canthus sparsely finely punctate, narrow and moderately long (1/3 of ocular width), with a terminal seta. Eyes moderately large, ratio of diameter/interocular width: 0.66. Antenna with ten antennomeres; club composed of four antennomeres, slightly reflexed at apex, 1.2 times as long as remaining antennomeres combined. Mentum elevated and slightly flattened anteriorly.</p><p>Pronotum wide, widest shortly before base, lateral margins evenly convex and convergent to blunt but distinctly produced anterior angles, posterior angles strongly rounded. Anterior margin of pronotum weakly convex, with fine and complete marginal line; basal marginal line absent; surface finely and densely punctate, with minute setae in punctures, anterior and lateral anterior margins sparsely setose. Hypomeron carinate, weakly produced ventrally. Scutellum triangular, finely and densely punctate, on midline narrowly impunctate.</p><p>Elytra short, widest at middle, striae distinctly impressed, finely and densely punctate, intervals convex, with fine and sparse punctures concentrated along striae, with very minute setae in punctures, odd intervals with a few short setae; epipleural edge robust, ending at slightly rounded external apical angle of elytra, epipleura densely setose, apical border chitinous, without a fringe of short microtrichomes (visible at ca 100x magnification).</p><p>Ventral surface dull, finely and densely punctate, metasternum sparsely covered with fine, short, or very minute setae; metacoxa glabrous, with a few single setae laterally. Mesosternum between mesocoxae as wide as mesofemur. Ratio of length of metepisternum/metacoxa: 1/1.76. Abdominal sternites finely punctate, with a transverse row of coarse punctures, each bearing a robust seta. Pygidium strongly convex and dull, with mixed finer and larger punctures, without smooth midline, with numerous short setae and a few longer in the larger punctures.</p><p>Legs moderately wide; femora finely and sparsely punctate, with two longitudinal rows of longer setae. Metafemur moderately shiny, anterior margin acute, without submarginal serrated line; anterior row of seta-bearing punctures present; ventral posterior margin finely serrate at apex, only weakly widened in apical half, dorsal posterior margin serrate, with a few short setae basally. Metatibia moderately long and wide, widest at middle, ratio width/length: 1/3.1; dorsal margin sharply carinate, with two groups of spines, basal group at middle, apical one at three quarter of metatibial length, in basal third with a few robust single setae; lateral face longitudinally convex, finely and sparsely punctate, along midline smooth, with minute setae in punctures; ventral edge finely serrate, with three robust equidistant setae; medial face smooth, apex interiorly near tarsal articulation sharply truncate. Tarsomeres with fine, sparse setae ventrally, neither laterally nor dorsally carinate, dorsally smooth; metatarsomeres glabrous, with a strongly serrated ridge ventrally and a parallel subventral smooth carina immediately beside it; first metatarsomere little shorter than following two tarsomeres combined, twice as long as dorsal tibial spur. Protibia short, bidentate; anterior claws symmetrical, basal tooth of both claws bluntly truncate at apex.</p><p>Aedeagus: Fig. 2A–C. Habitus: Fig. 2D.</p><p>Variation. The coloration of this species is quite variable, ranging from entirely yellow (females) to entirely black (some males).</p></div>	https://treatment.plazi.org/id/32553F1BFF9FFFA7FF3E77202D0FDFCF	Public Domain	No known copyright restrictions apply.

Eyes moderately large, ratio of diameter/interocular width: 0.64. Antenna with ten antennomeres; club composed of four antennomeres, weakly reflexed, 1.8 times as long as remaining antennomeres combined. Mentum elevated and slightly flattened anteriorly.</p><p>Pronotum wide, widest shortly before base, lateral margins evenly convex and convergent to rectangular and moderately produced anterior angles, posterior angles blunt and moderately rounded. Anterior margin of pronotum convex, with robust and complete marginal line; basal marginal line absent; surface finely and moderately densely punctate, with minute setae in punctures, anterior and lateral anterior margins sparsely setose. Hypomeron carinate, weakly produced ventrally. Scutellum triangular, coarsely and densely punctate, on median base less densely punctate.</p><p>Elytra short, widest at middle, striae finely impressed, finely and densely punctate, intervals weakly convex, with fine and sparse punctures concentrated along striae, with very minute setae in punctures, odd intervals with a few short setae; epipleural edge robust, ending at slightly rounded external apical angle of elytra, epipleura densely setose, apical border chitinous, without a fringe of short microtrichomes (visible at ca 100x magnification).</p><p>Ventral surface shiny, finely and densely punctate, metasternum sparsely covered with fine, short, or very minute setae; metacoxa glabrous, with a few single setae laterally. Mesosternum between mesocoxae as wide as mesofemur. Ratio of length of metepisternum/metacoxa: 1/1.62.

Gastroserica piceocoerulea Ahrens, Lukic &amp; Liu, new species is in external appearance similar to G. lucens (Ahrens &amp; Fabrizi, 2009), but in shape of aedeagus more similar to Gastroserica lucidomarginalis Ahrens, Lukic &amp; Liu, new species . Gastroserica piceocoerulea differs from G. lucidomarginalis Ahrens, Lukic &amp; Liu, new species by the dark body color, and by the shape of aedeagus: the phallobase is less curved (lateral view), its ventral lamina is reduced in length but present on both sides before apex of ventral phallobase (lateral view); the distal margin of the basal lobe of the left paramere is convex rather than sharply pointed as in G. lucidomarginalis Ahrens, Lukic &amp; Liu, new species . From G. lucens Ahrens &amp; Fabrizi, 2009, G. piceocoerulea differs by the longer antennal club and by the longer basal lobe of the left paramere.</p><p>Etymology. The name of the new species is derived from the combined Latin words “ piceus ” (black) and</p><p>“ coeruleus ” (blue) (adjective in singular nominative), with reference to the dark, iridescent shiny body surface. Variation. Length: 4.6–6.0 mm, length of elytra: 3.0– 3.5 mm, width: 2.8–3.2 mm. Female unknown. Genbank accessions.

Gastroserica bannok Ahrens, Lukic &amp; Liu, new species is in external appearance G. lucidomarginalis Ahrens, Lukic &amp; Liu, new species, while in shape of aedeagus it is more similar to G. cognata (Frey, 1972) . From the latter G. bannok Ahrens, Lukic &amp; Liu, new species differs by the lacking dots on the elytra and the shape of parameres: the phallobase is more strongly curved (lateral view) in G. cognata, the left paramere has the basal lobe more developed mesally rather basally, as in G. cognata . From G. lucidomarginalis Ahrens, Lukic &amp; Liu, new species G. bannok Ahrens, Lukic &amp; Liu, new species differs by the basal lobe of the left paramere being not developed distally but only mesally.</p><p>Etymology. The name of the new species is derived from the type locality, Ban Nok (noun in apposition).</p></div>	https://treatment.plazi.org/id/32553F1BFF8AFFB1FF3E7590291ED90F	Public Domain	No known copyright restrictions apply.

Despite the labelling on the holotype, the species was originally treated by Frey (1972) as a Triochoserica species. The systematic placement of this species is uncertain. Its morphology, particularly the serrated metatibia, the divergent genital morphology, and the constitution of the antenna are not retrieved in any other species of Microserica . Some affinities even with the species of the Neoserica calva group exist. However, given the reported strong homoplasy of the serrated metatibia in several other Sericini lineages and its considerable variation within some of these (e.g., Ahrens 2006; Bohacz &amp; Ahrens 2020) but also of the number of antennomeres composing the antennal club, we do not see very strong arguments for a robust classification of this species, neither to erect an independent genus for it at this moment.</p></div>	https://treatment.plazi.org/id/32553F1BFFAFFF96FF3E73602EA0DCD7	Public Domain	No known copyright restrictions apply.

Moronoserica Ahrens, Lukic &amp; Liu, new genus differs from its sister clade (Fig. 1), Trioserica Moser, 1922, by the bidentate protibia, the dorsal surface being more or less strongly covered with white scale-like setae, the strongly convex elytral intervals, and most of all by the strongly derived shape of aedeagus. The latter have the left paramere almost entirely reduced, the dorsoapical emargination of phallobase between the parameres extremely deep, it exceeds at least the half of the phallobasal length (the genital characters appear to be likely the only unambiguous synapomorphies). In contrast to all other Microserica species, the dorsal margin of metatibia is not carinate but longitudinally convex.</p><p>The phylogeny based on molecular characters has shown that the group is not monophyletic with the remainder Microserica species. So far, the species of this group have been treated as Microserica lineata group (Ahrens 2004; Bohacz &amp; Ahrens 2020). They are so far known only from Indochina.</p><p>Etymology. The genus name is composed by the root “ Serica ” (type genus of Sericini) and the name Morón. The new genus is dedicated to Miguel-Angel Morón (1952–2017), Mexican specialist of Melolonthinae, who passed away by far much too early.</p><p>Key to the species of Moronoserica Ahrens, Lukic &amp; Liu, new genus (♁♁):</p><p>1 Phallobase short, about twice as long as wide in right side lateral view.

Frons with fine and dense punctures, with minute white setae in punctures, beside eyes with a few long erect setae. Eyes small, ratio of diameter/interocular width: 0.53. Antenna yellow, with ten antennomeres; club with four antennomeres subequal in length, club as long as remaining antennomeres combined. Mentum weakly convexly elevated anteriorly.</p><p>Pronotum moderately wide, widest at base, lateral margins distinctly evenly curved and convergent anteriorly; anterior angles distinctly produced and acute, posterior angles blunt; anterior margin convexly produced medially, with a distinct and fine marginal line; basal margin without marginal line; surface with dense and fine punctures, with adpressed white minute setae in punctures; anterior and lateral borders sparsely setose; hypomeron carinate, its basal margin not produced ventrally. Scutellum narrow and short, with fine and dense punctures along lateral margins, otherwise at middle widely impunctate, minute setae present in punctures.</p><p>Elytra short oval, widest at middle, striae distinctly impressed and finely densely punctate; intervals strongly convex and densely finely punctate, punctures concentrated along striae, center of intervals impunctate, with fine white setae in punctures, with a few long, yellow setae on odd intervals; interior apical angle of elytron with a robust seta; before apex with an indistinct, dark, glabrous spot; epipleural edge robust but convex, ending at strongly convex external apical angle of elytra; epipleura densely setose, apical border broadly membraneous, with a rim of short microtrichomes.</p><p>Ventral surface dull, with fine and dense punctures, with dense short setae, setae adpressed; metacoxa minutely setose, laterally with robust adpressed setae; each abdominal sternite with indistinct transversal row of coarse and dense punctures, sternite bearing short strong setae between fine and dense punctation, all sternites bearing minute white setae. Mesosternum between mesocoxae almost as wide as mesofemur. Ratio of length of metepisternum/ metacoxa: 1/1.5. Pygidium strongly convex, with fine and dense punctures bearing fine, white setae, with a few longer yellowish setae, without smooth midline.</p><p>Legs moderately slender; femora on ventral surface dull, finely and moderately densely punctate, glabrous, with two longitudinal rows of setae; anterior edge of metafemur acute, with a robust adjacent continuously serrated line, posterior margin weakly convex and glabrous, ventrally weakly widened in apical half but not serrate, posterior margin dorsally not serrate. Metatibia moderately wide and long, dorsal and ventral margin almost subparallel, ratio width/length: 1/3.3, dorsally longitudinally convex, with two groups of spines, the basal group shortly before middle, apical one at three quarters of metatibial length, basally with a few single spines; lateral face longitudinally convex, with dense and moderately coarse punctures, along the middle of lateral face narrowly impunctate, punctures with minute to short setae, before the basal group of spines with a continuously serrated line; ventral margin sharp and serrated, with five strong and long, equidistant spines; medial face impunctate and smooth, apex interiorly (near tarsal articulation) distinctly truncate. Tarsomeres dorsally glabrous and impunctate, ventrally with a very few sparse, short setae; metatarsomeres ventrally with a single strongly serrated carina, a subventral carina lacking, first metatarsomere as long as following two tarsomeres combined and one third of its length longer than dorsal metatibial spur. Protibia short, bidentate, protarsal claws symmetrical.</p><p>Aedeagus: Fig. 20A–D. Habitus: Fig. 20E.</p><p>Diagnosis. Moronoserica squamulatoides Ahrens, Lukic &amp; Liu, new species differs from Mor. squamulata (Moser, 1915) new combination by fine white setae covering the elytral intervals instead of scales, and by the narrower and longer right paramere (lateral view).</p><p>Etymology. The name of the new species (noun in nominative singular case) is derived from the combined words, “ squamulatus ” (with scales) and the Greek suffix “- oides ”, with reference to the similarity to Mor. squamulata .</p><p>Variation. Length: 8.3–8.4 mm, length of elytra: 5.3–5.4 mm, width: 4.9–5.0 mm. Female: Antennal club composed of three antennomeres, little shorter than the remaining antennomeres combined.</p></div>	https://treatment.plazi.org/id/32553F1BFFA8FF93FF3E74F328E0DAE7	Public Domain	No known copyright restrictions apply.

Oxyserica bifascipennis Ahrens, Lukic &amp; Liu, new species resembles in external appearance the O. marginata (Brenske, 1898), while in shape of aedeagus it is similar to O. nigropicta (Fairmaire, 1891) and O. diversicornis (Moser, 1915) . Oxyserica bifascipennis Ahrens, Lukic &amp; Liu, new species differs from all of them by the larger body size, and, of course, in shape of parameres: the distal margin of phallobase (lateral view) is reflexed, the ventral lobes of parameres which are in the new species as well as in O. nigropicta and O. diversicornis subsymmetric, are longer than half of the phallobase in Oxyserica bifascipennis .</p><p>Etymology. The name of the new species is derived from the combined Latin prefix “ bi ” (two-), and the words “ fascis ” (stripes) and “ pennis ” (wing).</p><p>Variation. Length: 7.0– 7.2 mm, length of elytra: 5.1–5.4 mm, width: 4.3–4.4 mm. Female: Antennal club composed of three antennomeres, little shorter than the remaining antennomeres combined.</p></div>	https://treatment.plazi.org/id/32553F1BFFDBFFE2FF3E74F328E0DAC3	Public Domain	No known copyright restrictions apply.
