Redescription. Body dark; maxillary palpi, antennae, elytra, and legs brownish. Length [average]: ♂, 4.3 mm; ♀, 4.4 mm.

Male. Head ( Figs. 1 View FIGURE 1 A; 2A) broadest at temples, some cases at eyes. Disc coriaceous, nearly glabrous, with punctures dense. Clypeus transverse, with anterior margin slightly emarginate, in center furnished with tiny process, bordered with membrane. Epistomal suture with middle portion absent, lateral portions short and posteromedially directed. Supra-antennal ridges obviously elevated. Vertex depressed in anterior part, convex at each side of mid-longitudinal suture; mid-longitudinal suture short and deep, posteriorly reaching occipital suture. Eyes slightly convex, shorter than temples, with fine facets; orbital sulcus fine. Temple dilated laterally. Occipital suture deep and arciform, with large setal fovea at each end. Mandible ( Fig. 2 View FIGURE 2 C) long, stout, and incurved at apex; bearing 3 teeth on inner edge: 2 large with 1 tiny in between; with tiny spur situated in fovea at middle of dorsal surface.

Pronotum ( Figs. 1 View FIGURE 1 A; 2A) a little wider than head, widest at anterior 1/3, with mid-longitudinal sulcus throughout, with punctures sparser and smaller than in head, micro-striate between punctures; anterior margin biemarginate, anterior lateral angles produced, no posterior angles; lateral and posterior margins integrated and evenly rounded, without crenulation.

Aedeagus ( Figs. 1 View FIGURE 1 G–I; 2I –K) with median lobe inflated at base; apical orifice large and fissured to middle of ventral surface and embedded with sharp triangular sclerite there, edges of ventral fissure dully protruding, incrassated, and sparsely pubescent near apex; internal sac membranous. Paramere arm-like, basal arm with furrow on ventral surface; apical arm furnished with 3 setae: one at apex, one stout nearing apical 1/4 of paramere, and one tiny at notch in between; pits lined on ventral edge of apical arm.

Female. Head ( Figs. 1 View FIGURE 1 B; 2B) smaller and narrower than male; clypeus with two small teeth neighbored in middle of anterior margin; vertex slightly convex at side of mid-longitudinal suture; eyes convex, nearly equal to temples in length, temples not dilated. Mandibles ( Fig. 2 View FIGURE 2 D) shorter and sharper than in male. Pronotal anterior margin ( Figs. 1 View FIGURE 1 B; 2B) with bi-emargination weak. Abdominal sternite VII with posterior margin straight.
