This species is diagnosed by the following morphological characters: ♂ frons shallowly concave, surface shiny with punctures, denser towards epistoma; thick, curled tuft of hairs, touching each other at the middle of frons, covering frontal two-third portion; pronotum 1.3× wider than long; surface shiny, median line inconspicuous, with distinct, dense punctures and moderately fine hairs; scutellum submerged; elytra 1.54× as long as its width, 2.1× as long as pronotum, basal margin weakly crenulate; discal striae 1 and 2 distinctly impressed up to the commencement of declivity; striae marked by shallow punctures; interstriae nearly three times as wide as striae, surface roughened, marked with small granules, becoming distinct towards declivity and covered with irregular rows of short scale-like setae; declivity strongly convex; striae 1 and 2 indistinct; interstria 1 marked by granules and scale-like setae; interstria 2 terminating at the commencement of declivity, others also well marked with small granules; body dark-brown, body length: 2.10–2.16 mm, 2.46× as long as wide.

Females are similar to males but the frons is devoid of any tuft of hairs but with a pair of tubercles at its middle; elytral interstriae are roughened with somewhat distinct granules; body length: 2.49–2.63 mm.
