Redescription. Body nearly black, shining, elytra brownish; mouthparts, antennal dark brown, legs yellow. Forebody sparsely pubescent, punctate and striate. Body length [average] male, 3.65 mm; female, 3.40 mm.

Male: Head (Fig. 14-1C, 14-2A) slightly broader than pronotum. Disc with sparse large punctures and dense striae, vertex slightly flat, mid-longitudinal sulcus broad and deep, with deeper impression on each side before base. Supra-antennal ridge with margin incrassate. Temples dilated, approximately two times as long as eyes. Clypeus nearly square, about 1/3 of total head length, convex, coriaceous, with very few punctures, anterior margin rounded and produced. Epistomal suture with lateral portions straight and parallel, running backward to level of anterior margin of eyes.

Occipital suture straight or slightly curved forward in middle. Antenna filiform, segment IV globular, VI–X short and transverse, with ultimate article stilliform. Neck without smooth area.

Pronotum (Fig. 14-1D, 14-2A) slightly transverse, broadest at near anterior 1/3; disc slightly convex, with sparse longitudinal striae and punctures; mid-longitudinal sulcus deep and broad, changing narrow and deep to base, with two broader and shallower paramedial sulci, and bounded by sharp longitudinal carina, shallow depression close to each lateral margin. Anterior margin slightly broadly emarginate in middle and anterior angles only slightly protruded. Posterior angles observable. Scutellum with crest-shaped impression and median lobe sharp. Elytra densely sculptured and punctured, not pubescent; lateral margin curved and posterior margins truncate. Abdomen coriaceous, covered with punctures and pubescence. Sternite VII (Fig. 14-1G, 14-2C) with posterior margin slightly emarginate and bearing long setae laterally. Sternite VIII (Fig. 14-1H, 14-2D) with posterior margin broadly emarginate in middle and bearing long setae laterally.

Aedeagus (Fig. 14-1J–L, 14-3A–C) with median lobe oval, inflated at base and shortly narrowing to apex; apical orifice large and ventral orifice crescentic; internal sac of median lobe with complicated sclerite. Parameres (Fig. 14-1M, 14-3D) arm-like, closely situated to each other and twining around median lobe; with apex slightly flattened and enlarged; ventral edge of parameres each with thick short seta at middle.

Female. Head (Fig. 14-1E, 14-2B) smaller than pronotum (Fig. 14-1F, 14-2B); supra-antennal ridge running backward to near base; temples short and convergent posteriorly. Sternite VII (Fig. 14-2E) with posterior margin slightly produced. Sternite VIII (Fig. 14-1I, 14-2F) with posterior margin broadly rounded and protruded gradually. Spermatheca (Fig. 14-1N, 14-3E) with base bulb-like, with apical part clavate and slightly curved.

Distribution. China (Liaoning, Shanghai, Sichuan, Yunnan); Japan.
