Length 3.0–
3.8 mm
. Body (

F) parallel-sided; surface glossy and densely pubescent, with microsculpture. Body reddish brown to black; head, pronotum, abdomen almost black; elytra and legs paler than other parts.
Head
. Subquadrate, about as wide as long, widest across eyes, slightly narrower than pronotum; eyes slightly large and prominent, about 1.3–1.4 times as long as temples; gular sutures moderately separated; infraorbital carina complete; diverged basally; cervical carina complete. Antennae (

Mouthparts
. Labrum transverse, slightly emarginate in anterior margin, with ε-sensillum and about 9 macrosetae on each side of midline; epipharynx with several sensilla, including 2 lateral sensory rows on each side of midline; α-sensillum long and setaceous, about 2.0 times as long as εsensillum, β- and γ-sensilla very short. Mandibles asymmetrical, subtriangular, decurved and pointed apically, about 1.5–1.6 times as long as basal width; minute denticles present in molar region; right one with small internal tooth, internal margin slightly serrulate; prostheca developed, composited three portions. Galea and lacinia of maxilla long and slender; lacinia composited seven spines in distal comb region, contiguous with two isolated spines; maxillary palpus elongate, with pubescence and long setae; palpomere 1 smallest, 2 about 2.4–2.6 times as long as wide, 3 slightly longer than 2, about 2.8–3.0 times as long as wide, 4 digitiform, filamentous sensilla reaching to basal half. Labium with ligula divided into 2 lobes in basal half; prementum with two medial setae widely separated; two basal pores moderately separated, about 1.0–2.0 times width of basal pore; several medial pseudopores, 1 setal pore and 2 real pores present on each side of midline; labial palpus with many setulae; palpomere 1 largest, about 1.7–1.9 times as long as wide, γ-setula contiguous with b-seta, 2 shortest, about 1.2–1.4 times as long as wide, 3 subparallel-sided and about as long as 1, about 3.0–3.5 times as long as wide. Mentum trapezoidal, anterior margin slightly emarginate; v-seta very short, close to u-seta.
Thorax
. Pronotum slightly transverse, approximately 1.1–1.2 times as wide as long, widest in apical third to half; hypomera fully visible in lateral aspect. Metanotal scutum with 2 long setae and about 3–4 relatively short setae on each side of midline. Mesocoxal cavities narrowly separated, mesoventral process pointed at apex, slightly longer than isthmus and metaventral process combined; isthmus slightly longer than metaventral process. Elytra transverse, slightly wider than pronotum; elytron approximately 1.5–1.6 times as long as wide, pubescence directed posteriorly and posterolaterally; postero-lateral margin almost straight; hind wings fully developed, flabellum composed of about 9–11 long setose lobes.
Legs
. Slender and long, with pubescence and macrosetae; meso- and metatibiae with different length of two spurs at apex; tarsal formula 4-5-5, length ratio of tarsomeres 33:37:39:89 (protarsus); 39:48:48:45:89 (mesotarsus); 71:69:61:56:106 (metatarsus); one empodial seta present, slightly shorter than claw.
Abdomen
. Parallel-sided; surface distinctly glossy and densely pubescent, with transverse and imbricate microsculpture; macrochaetal arrangement of tergites
II–VI 01-23-23
-23-23; male tergite VIII (

B) with 4–5 macrosetae on each side of midline, posterior margin slightly crenate in median region; male sternite VIII (
Fig. 7
C) with 9–10 macrosetae on each side of midline, posterior margin convex, slightly round, with long marginal setae; female tergite VIII (
Fig. 7
D) with 4 macrosetae on each side of midline, posterior margin subtruncate; female sternite VIII (
Fig. 7
E) with 7 macrosetae on each side of midline, posterior margin broadly round, with conspicuous marginal setae, minute setae present in median region.
Aedeagus
. Median lobe (
Figs. 7
F–G) narrowly ovate and widest in basal fourth, apical process constricted basally and convergent at apex in ventral aspect; internal sac elongate. Apical lobe of paramerites (
Fig. 7
H) with four setae; a-seta longest, c- and d-setae shorter than b-seta, close together and positioned apically.
Spermatheca
. Bursa globular apically, with small umbilicus; duct simply coiled (
