This species is diagnosed by the following morphological characters: ♀ frons plano-convex; surface coarsely reticulate with some sparse minute granules, a short median carina just above epistoma, feebly impressed on either sides; vertex finely reticulate; frontal surface with sparse fine hairs, longer and denser towards epistoma, epistomal margin with fringe of pale yellow hairs at middle; eyes oval, emarginated anteriorly on less than one-third of its width; antennal scape long, funicle with four segments; club flat, oval with three straight or slightly procurved sutures marked by pale, short hairs; pronotum 1.18× as wide as long, widest slightly above base; lateral sides rounded gently narrowing anteriorly towards rounded apex; anterior margin set with six to seven distinctly spaced asperities; pronotal summit distinctly humped and placed more towards base, anterior slope steeply declivous with approximately fifty distinct, irregularly placed asperities, denser towards summit; prontal disc less than one-fourth the length of pronotum, surface below summit and postero-laterally somewhat impressed and reticulate with fine granules; entire surface with erect, fine hairs longer anteriorly and laterally; scutellum small, triangular; elytra 1.80× as long as pronotum; elytral base wider than pronotum and the suture between pronotum and elytra sinuate; lateral sides widest at base converging posteriorly with rather broadly rounded apex; elytral disc somewhat convex; striae narrow marked by small, closely placed punctures, distinctly indicated almost up to declivity, each with a microhair; interstriae more than three times wider than striae; interstrial surface with dense coat of minute, feather-like scales and fine punctures; each interstria with a row of erect, hair-like bristles with pointed apices, denser and longer laterally; declivity rounded and sloping with uneven surface, interstriae relatively of variable width with same vestiture as on disc; procoxae with sparse, somewhat longer hair-like setae; protibiae and protarsi with short, hair-like setae; mesocoxae moderately separated, more than distance between metacoxae; abdominal ventrites with fine, short hair-like setae; head and pronotum dark-brown, elytral vestiture translucent yellow-brown with a weak iridescence; body length: 1.91–1.94 mm, 2.10× as long as wide.

Male similar to the female, except pronotal asperities slightly smaller; body length: 1.87–1.90 mm, 1.96× as long as wide.
