Male. Length 4.4 mm, width 3.2 mm

Head, pronotum, elytra, and scutellum green, antennae and legs brown, ventral surface of body yellowish brown.

Vertex finely and sparsely covered with punctures; frontal tubercle distinctly raised, separated from each other by a deep furrow; antennae short, robust, extended to the middle of elytra; antennomeres 1-3 thin, shiny; antennomeres 4-11 wide and flat, with short hairs, antennomeres 2 and 3 shortest, antennomere 3 similar in length and shape to antennomere 2, antennomere 4 longest, 1.2 × as long as antennomeres 2 and 3 combined; antennomeres 5-10 differ in length, shorter than 4; antennomere 11 slightly longer than 10, pointed.

Pronotum approximately 2.5 × as wide as long, with rounded lateral margins; disc sparsely covered with punctures, with a lateral pair of shallow impressions.

Scutellum triangular, covered with small punctures.

Bases of both elytra wider than pronotum, gradually widen posteriorly and rounded at apex; dorsal surface slightly convex, irregularly covered with large and deep punctures, the interstices between punctures slightly wider than the diameter of individual punctures and covered with small punctures.

Metasternum 2.5 × as long as mesosternum, Anterior metasternal process extending beyond the front edge of the meso-coxal cavities; prothoracic legs shortest, mesothoracic legs slightly longer, metathoracic legs longest.
