(♂) Length 4.5–6.0 mm. Head, pronotum, scutellum, ventral surface of body, femur, and base of tibia reddish brown or yellowish brown; antennae ranged from black to brown with antennomeres 1–3 yellow; in some specimens antennae yellow with antennomeres 7–11 black-brown. Elytra yellow; apical half of tibia, tarsus, and claw brown.

Vertex covered with closed punctures. Frontal tubercles small, antennae longer than body. Antennomere 1 bare, rod-shaped, antennomeres 2–11 with short hairs, antennomere 2 shortest, antennomere 3 ~ 3 × as long as antennomere 2; antennomere 4 ~ 1.2 × as long as antennomere 3, antennomeres 4–11 equal in length.

Pronotum ~ 2 × as wide as long, basal and apical margins slightly convex, disc strongly convex with dense punctures.

Scutellum triangular, smooth, impunctate.

Elytra wider than pronotum basally, humeri strongly convex, subparallel-sided but gradually widened posteriorly. Disc with 8–10 longitudinal grooves, covered with dense punctures, interstices of punctures narrower than diameter of individual puncture. Elytral epipleuron broad at base, strongly narrowed at middle, gradually narrowed from middle to apex.

Legs strong, each tibia with distinct spur at apex, segment 1 of hind tarsi equal to combined remaining segments.

Aedeagus robust, with parallel sides and rounded apex in ventral view. Apical protrusions nipple nipple-shaped, small, well separated from each other.
