Redescription. Body dark brown; mouthparts and legs yellow. Forebody slightly pubescent, punctate and striate, with coriaceous and depressed intervals. Body length [average] 4.25 mm.

Female: Head (Fig. 13-1B, 13-2A) slightly broader, but narrower than pronotum. Vertex extremely convex, with a pair of raising parts glabrous and curved, with deep sulcus running parallel in middle; all depressed parts coriaceous. Supra-antennal ridge with margin incrassate. Temples as long as eyes. Clypeus nearly square, coriaceous, about 1/2 of total head length, with anterior margin roundly produced. Epistomal suture with lateral portions straight and parallel, running backward to level of anterior margin of eyes. Occipital suture nearly straight. Antenna filiform, segment IV globular, V–X short and transverse, with ultimate article stilliform. Neck without smooth area.

Pronotum (Fig. 13-1B, 13-2A) transverse, broadest at near anterior 1/4; disc slightly convex, mid-longitudinal sulcus broad and shallow, narrowing and deepening to base, with two shallow, straight paramedial sulci, and bounded by two obtuse glabrous longitudinal carinae carrying big punctures, and two shallow para-lateral depressions close to lateral margins. Anterior margin slightly and broadly bi-emarginate, with anterior angles slightly protruded. Lateral margin weakly crenate in posterior 1/4. Lateral and posterior margins running nearly continuously, posterior angles less distinguishable. Scutellum with crest-shaped impression with median lobe sharply pointed. Elytra with fine and moderately dense striae and punctures, not pubescent; lateral margin curved and posterior margins truncate. Abdomen coriaceous, covered with punctures and pubescence.

Sternite VII (Fig. 13-1D, 13-2B) with posterior margin straight, and bearing long setae laterally. Sternite VIII (Fig. 13-1E, 13-2C) with posterior margin broadly rounded and protruded. Spermatheca (Fig. 13-1F, 13-2D) with base bulb-like, with apical part clavate and slightly curved.

Distribution. China (Jiangsu).
