Redescription. Body black; elytra brownish; legs brown. Forebody densely punctate and moderately striate, puncture interval very narrow. Body length [average] male, 4.17 mm; female, 3.90 mm.

Male: Head (Fig. 11-1C, 11-2A) slightly broader than pronotum. Disc slightly convex, with big round punctures and coarse longitudinal striae; vertex slightly flat, mid-longitudinal sulcus deep, with shallower 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 and coriaceous, with small round punctures; anterior margin straight, not 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, V–X short and transverse, ultimate one stilliform. Neck without smooth area.

Pronotum (Fig. 11-1C, 11-2A) transverse, broadest at near anterior 1/3; disc slightly convex, with dense round punctures and less striate, denser laterally; mid-longitudinal sulcus broad and shallow, narrowing and deepening, paramedial sulci shallower and broader, bounded by obtuse longitudinal carina; shallow depressions close to lateral margins. Anterior margin broadly emarginate, with anterior angles distinctly protruded. Lateral margin crenate on posterior half. Posterior margin much protruded posteriorly. Lateral and posterior margins running continuously, curve-formed, with posterior angles not obvious but distinguishable. Scutellum with crest-shaped impression, median lobe sharp. Elytra coarsely striate-punctate, not pubescent; lateral margin curved and posterior margins truncate and slightly slant. Abdomen coriaceous, covered with punctures and pubescence. Sternite VII (Fig. 11-1E, 11-2C) with posterior margin with abrupt and deep narrow emargination in middle and flat processe carrying some seta on each side of the emargination, outside weakly emarginate and bearing long setae laterally; sternite VIII (Fig. 11-1F, 11-2D) with posterior margin almost straight and bearing long setae laterally.

Aedeagus (Fig. 11-1H–J, 11-3A–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. 11-1K, 11-3D) arm-like, closely situated to each other; apex much flattened and enlarged, with large seta at middle of ventral edge of each paramere.

Female. Head (Fig. 11-1D, 11-2B) smaller than male, narrower than pronotum (Fig. 11-1D, 11-2B). Temples shorter than eyes. Sternite VII straight or slightly emarginate. Sternite VIII (Fig. 11-1G, 11-2E) with posterior margin broadly protruded and gradually narrowing to middle tip. Spermatheca (Fig. 11-1L, 11-3E) with base bulblike, with apical part clavate and slightly curved.

Distribution. China (Beijing, Liaoning, Shanghai, Jiangsu, Anhui, Hubei, Guangxi, Sichuan, Yunnan, Shaanxi, Gansu, Ningxia); South Korea; Japan; Belgium.
