03C887E8C45D7C3BDAB0FC53BA2AF88D.taxon	description	Description. Body relatively elongate, rather flattened, about 1.3 mm long, 0.5 mm wide, moderately densely setose. Head prognathous, not retracted into prothorax. Eyes well developed, moderately protuberant, coarsely facetted, without interfacetal setae (Fig. 4 A, D). Antennal grooves absent (Fig. 4 B, D). Antennal sockets visible from above (Fig. 5 C). Antennae (Figs 4 C, D, 5 F) composed of nine antennomeres; antennomere 2 oblong; antennomeres 3 – 6 moniliform; antennomeres 7 – 9 forming a distinct club; antennomere 7 strongly asymmetrical, short and strongly transverse; antennomere 8 strongly enlarged. Maxillary palps (Fig. 4 B) 4 - segmented, palpomere 1 smallest; palpomeres 2 – 4 narrowing progressively; palpomere 4 about as long as 2 and 3 combined, conical. Labial palps (Fig. 4 B) 3 - segmented, with apical palpomere apparently enlarged. Pronotum (Fig. 3 A) transverse, widest near the middle, narrower at base than elytral bases; lateral pronotal carinae complete, without raised margin (Fig. 5 D); anterior angles not produced; disc without pits, sulci or carinae. Elytra about 1.8 times as long as width combined, completely covering abdomen; sides weakly rounded; disc irregularly punctate; epipleura comparatively narrow, incomplete towards apices. Mesocoxal cavities circular, moderately widely separated, laterally broadly closed by meeting of meso- and metaventrites (Fig. 4 E); mesotrochantins concealed; mesoventral process narrower than coxal cavity, narrowing between coxae towards apex, without apparent carinae or grooves (Fig. 4 E). Mesometaventral junction as straight line with meso- and metaventrites contiguous (Fig. 4 E). Metaventrite without postcoxal lines; postcoxal pits not apparent. Metacoxae (Fig. 4 F) widely separated, transverse. Hind wings well developed. Legs relatively long and slender. Trochanterofemoral joint oblique. Femora with deep and long groove (nearly throughout their length) for receiving tibiae (Fig. 4 E, F). Tibiae without apical spurs, with short spines surrounding apex (Fig. 4 H). Tarsi 3 - 3 - 3; tarsomeres simple (Fig. 4 H, I). Pretarsal claws simple. Abdomen (Fig. 4 F, G) with six ventrites; ventrite 1 slightly longer than ventrite 2 – 4 combined, without postcoxal lines.	en	Li, Yan-da, Tomaszewska, K.
