Punctation strong and deeply impressed, but sparse; punctures stronger than that of the head, larger at posterior margins, sparse near suture and anteriad, surface very depressed at projections along posterior margin.

Elytra punctation of two series; first series with nine or ten distinct and almost regular rows of large deeply impressed punctures; increasingly scattered, finer, not as strongly impressed as in rows laterally and posteriorly; intervals and interstices distinctly broader than punctures; second series of small punctures moderately dense only and less conspicuous than in previous species. Pubescence long, brown, with yellowish shade depending on illumination, of two distinct types: erect series on sides, slightly recumbent series on disc; erect series longer and denser; disc series shorter, sparse. Scutellum subtriangular, with few punctures and pubescence similar to surrounding area of elytra. Metathoracic wings well developed. Epipleura almost flat.

Metasternum minutely perforate at sides, with raised triangular, rugulose area behind cavities; raised area comprising nearly half of surface; metasternal ridge along posterior margin of metasternum faint laterally, well-developed medially. Abdominal punctation finer at mid-line than at sides; surface between punctation with polygonal network, with median pore. Intermetacoxal plate on ventrite I triangular, strongly acuminate.

Tarsi 5-5-5, dark yellow to light brown, paler towards the apex, about two-thirds of length of tibia; tarsomere length ratio ca. 1.2:1.0:1.0:1.0:2.9 (1.0-1.5: 0.8-1.0: 0.8-1.0: 0.8-1.0: 2.7-3.3); tarsomere 1 brown, with parallel margins, widest towards the apex, with dense comb of setae; tarsomeres 2-4 almost globular, outer edge with long yellow spiny setae on both sides, remaining portions with sparse minute setae; tarsomere 5 more yellow than brown, widest towards the apex, with at least three pairs of long robust spiny setae.
