Redescription. Body dark brown, with hind parts of elytra and abdomen relatively dark; basal part of antenna and legs brownish. Forebody sparsely pubescent, punctate and striate. Body length [average] male, 4.26 mm; female, 4.01 mm.

Male: Head (Fig. 15-1C, 15-2A) slightly broader than pronotum. Vertex flat, with small round punctures, intervals large and glabrous; mid-longitudinal sulcus deep and short, with deep 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, sparsely covered with 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. 15-1D, 15-2A) transverse, broadest at near anterior 1/3; disc slightly flat, with punctures and striae, denser laterally; mid-longitudinal sulcus deep and narrow, with two shallower and broader paramedial sulci, bounded by obtuse longitudinal carina; shallow depression close to lateral margins. Anterior margin nearly straight. Posterior angles observable and obtusely rounded. Scutellum with crest-shaped impression, with median lobe sharp. Elytra with fine and moderately dense striate and puncture, not pubescent; lateral margin curved and posterior margins truncate. Abdomen coriaceous, covered with punctures and pubescence. Sternite VII (Fig. 15-1G, 15-2C) with posterior margin slightly emarginate in middle, and bearing long setae laterally; Sternite VIII (Fig. 15- 1H, 15-2D) tri-lobed and bearing long setae laterally, with middle round process not beyond lateral angles posteriorly.

Aedeagus (Fig. 15-1J–L, 15-3A–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 simple sclerites. Parameres (Fig.

15-1M, 15-3D) flattened and enlarged, closely situated; with apex slightly narrow; with large seta and a few pubescence at middle of ventral edge of each paramere.

Female. Head (Fig. 15-1E, 15-2B) smaller than male, narrower than pronotum (Fig. 15-1F, 15-2B). Temples shorter, shorter than eyes. Sternite VII (Fig. 15-2E) with posterior margin almost straight, and attached some long setae laterally. Sternite VIII (Fig. 15-1I, 15-2F) with posterior margin broadly rounded and protruded posteriorly. Spermatheca (Fig. 15-1N, 15-3E) with base bulb-like, with apical part clavate and slightly curved.

Distribution. China (Anhui, Fujian, Guangxi, Jiangsu).
