Redescription. Body dark brown, fairly shiny; elytra dark yellow; basal segment of antenna black; legs yellow. Forebody densely punctate and moderately striate. Body length male, 3.50 mm; female, 3.40 mm.

Male: Head (Fig. 10-1C, 10-2A) slightly broader than pronotum. Disc convex, with some big round punctures and coarse longitudinal striae, denser laterally; vertex flat, mid-longitudinal sulcus deep and long, 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 trapezoidal, about 1/3 of total head length, convex and coriaceous, sparely punctate, with anterior margin produced and nearly straight. Epistomal suture with lateral portions straight and obliquely inward, running backward to level of middle of eyes; separated by coriaceous ground sculpture from the rest of surface.

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

Pronotum (Fig. 10-1D, 10-2A) not obviously transverse, broadest at near anterior 1/3; disc slightly convex, with sparse punctures, mid-longitudinal sulcus deep and narrow, with two shallower and broader paramedial sulci and bounded by two obtuse longitudinal carinae, with two shallow para-lateral depressions close to lateral margins. Anterior margin straight, anterior angles produced. Lateral margins crenate but not obvious, hind 2/3 convergent straightly. Posterior angles rounded and obtuse. Scutellum with crest-shaped impression, with median lobe sharp. Elytra with fine and moderately dense striate punctures, not pubescent; lateral margin curved and posterior margins truncate and slightly slant. Abdomen coriaceous, covered with punctures and pubescence. Sternite VII (Fig. 10-1G, 10-2C) with posterior margin weakly emarginate and bearing long setae laterally; sternite VIII (Fig. 10-1H, 10-2D) with posterior margin broadly bi-emarginate and bearing long setae laterally, acutely angulate in middle, middle tip not beyond lateral angles posteriorly.

Aedeagus (Fig. 10-1J–L, 10-3A–C) with median lobe elongate, inflated at base and shortly narrowing to apex; apical orifice large and ventral orifice crescentic; internal sac of median lobe with complicate sclerites. Parameres (Fig. 10-1M, 10-3D) closely situated to each other and twining around median lobe; flattened and slightly enlarged at base; at middle of ventral edge of each paramere with large seta and a few pubescence.

Female. Head (Fig. 10-1E, 10-2B) smaller than male, narrower than pronotum (Fig. 10-1F, 10-2B). Head and pronotum with sculpture coarser and dense than male. Temples shorter, as long as eyes. Sternite VII (Fig. 10-2E) with posterior margin almost straight. Sternite VIII (Fig. 10-1I, 10-2F) with posterior margin broadly rounded and protruded, middle angle slightly beyond lateral angles posteriorly. Spermatheca (Fig. 10-1N, 10-3E) with base bulb-like, with apical part clavate and slightly curved.

Distribution. China (Jiangsu).
