Head (particularly frons and vertex) with dense pale yellowish pubescence except median frontal groove and a longitudinal glabrous area on vertex. Pronotal disc with fairly dense pale yellowish pubescence without distinct longitudinal pubescent stripes; ventral side of prothorax with very dense pale yellowish pubescence. Each elytron with a vague subtriangular glabrous mark, extending from shoulder to basal 1/3, without a distinct margin; some part of mark covered with sparse pubescence; disc of each elytron with 4 longitudinal lines of dense pale yellowish pubescence interspaced with glabrous longitudinal carinae. Meso- and metasterna, abdomen, and legs covered with fairly dense white pubescence.

Head. Postclypeus semicircular and slightly convex, with dense coarse punctures; frontoclypeal suture deep and narrow in middle; distance between lower lobes of eyes 1.55 × as long as distance between upper lobes of eyes; distance between upper lobes of eyes 1.42 × as long as distance between eyes on ventral side; genal length 0.40 × as long as head width immediately below eyes. Antennae slightly shorter than or as long as body; segments 4–10 flattened and produced on one side at apex; apical ¼ of segment 11 suddenly becoming thinner.

Thorax and abdomen. Pronotum 1.35 × as long as width, with an angular process at each side; posterior margin 1.16 × as wide as anterior margin; pronotal disc binodulose in middle and rugose transversely near anterior and posterior margins. Scutellum semicircular, with dense pubescence. Elytra 3.53 × as long as prothorax and 3.32 × as long as shoulder width; each elytron with 3 feeble longitudinal carinae; basal elytra moderately punctate; apex narrowly emarginate and bispinose, sutural spine longer than marginal one.
