Description. Integument black. Prothorax and back of head reddish orange. Pronotum medially with a longitudinal irregular black vitta from apex to base, sometimes interrupted at apical half, enlarged from middle to base where it almost reaches the sides of prothorax. Head opaque. Frons punctocorrugate, clothed with yellowish pubescence, denser near clypeus. Vertex velvet­like, with coarse, irregularly dense punctures and numerous erect yellowish hairs. Clypeus and genae shiny, finely punctocorrugate. Genae ⅔ as long as lower eye lobes. Antennae with scape opaque, subglabrous; segments 3– 11 with scattered, fine punctures; segments from 5 denser whitish pubescent. Prothorax cylindrical, more attenuate at apical third, somewhat enlarged from middle to basal third. Pronotum moderately raised at middle, with a prominent gibbosity on each side near base, transversely impressed behind middle; surface opaque, almost impunctate, basal half coarsely, transversely, irregularly to confluently rugose, apical half with numerous long whitish hairs. Sides of prothorax subopaque, impunctate, shallowly, sparsely rugose. Prosternum shiny. Elytra proportionally shortened and broad, strongly impressed on each side of scutellum; surface, except humeri and base which are subglabrous, densely clothed with silky, whitish pubescence, not obscuring punctures. Intercoxal process of prosternum, mesosternum, metasternum and urosternites clothed with short, silky, whitish pubescence, not obscuring punctures. Metasternum and urosternites with very dense, long, whitish hairs. Metasternum with coarse, deep, irregularly dense punctures. Punctures of urosternites shallow, close, finer than on metasternum. Femoral peduncles very sparsely yellowish setose; clubs yellowish pubescent with scattered, erect setae. Tibiae opaque, with long, whitish hairs. First urosternite as long as the following three combined.

Measurements, in mm, respectively for?//: total length, 9.8–10.5/10.3; prothorax length, 2.5–2.7/2.8; prothorax width, 1.8–2.2/2.0; elytral length, 6.0–6.5/6.3; humeral width, 2.3–2.7/2.6.
