Description.
Body length about 3.0 mm. Body (
Fig. 1
E) moderately elongate. Head almost black; antennae and pronotum dark brown; elytra and legs yellowish brown to brown; abdominal tergites dark brown to black, posterior margin of each tergite paler. Head surface glossy, with fine punctation, distance between punctures 2–3 times longer than their diameter; head approximately 1.1 times longer than wide, widest across eyes; eyes prominent, about 1.2 times as long as tempora; antennomeres 4–5 slightly elongate, 6–10 about as long as wide, 11 little shorter than preceding two combined (
Fig. 6
A); labrum (
Fig. 6
B) emarginate in anterior margin, a-sensillum relatively short; prementum with medial and lateral pseudopores. Pronotum slightly transverse, approximately 1.15–1.20 times as wide as long, widest at apical fourth; pubescence in midline directed anteriorly, in apical half antero-laterally, in basal half posteriorly; distance between punctures 1.5–3.0 times longer than their diameter; metanotal scutum with one long seta and about 4–5 relatively short setae on each side of midline; mesoventral process elongate and more or less pointed at apex, longer than metaventral process; length ratio of mesoventral process, isthmus and metaventral process 9:5:3 (
Fig. 6
C). Elytron approximately 1.65 times as long as wide, postero-lateral margin straight; flabellum composed of about 20 setae. Abdominal tergites glossy, with fine punctation, distance between punctures 0.5–1.0 times longer than their diameter; tergites VIII (
Fig. 6
D) with 5 macrosetae on each side of midline; posterior margin of male tergite VIII slightly emarginate; male sternite VIII (
Fig. 6
E) more or less round in posterior margin, with 12 macrosetae on each side of midline; posterior margin of female tergite VIII weakly emarginate at middle; posterior margin of female sternite VIII slightly round, with short marginal setae. Aedeagus as in
