Description. Length 3.0- 3.5 mm; oblong, convex, head and pronotum moderately shiny, elytra almost dull, pubescent. Blackish brown, sometimes elytra vaguely reddish brown; legs dark brown, antennal club blackish. Head with epistome feebly gibbous and finely alutaceous on disc, almost evenly, not closely punctured; punctation sparser on disc; clypeus feebly sinuate at middle, obtusely rounded at sides, rather thickly bordered, edge slightly reflexed, glabrous; genae rounded, sparsely ciliate, feebly more protruding than eyes; frons rather coarsely, evenly, not closely punctured. Pronotum weakly transverse, strongly convex, superficially alutaceous thus moderately shiny, dually, coarsely, densely punctured and with a narrow longitudinal median areola impunctate; punctation laterally with extremely short, recumbent hairs; large umbilicate punctures, four or five times larger than small, evenly scattered throughout as well as smaller punctures; lateral margins feebly arcuate, distinctly bordered, edge sparsely ciliate; hind angles obtusely rounded; base rather thickly bordered. Scutellum elongate, coarsely irregularly punctured on basal half. Elytra elongate, convex, slightly widened posteriorly; striae rather deep, distinctly punctured, crenulate; intervals feebly convex, distinctly alutaceous thus rather dull, coarsely, densely, somewhat irregularly punctured, distinctly pubescent, remarkably so laterally and toward apex. Hind tibiae apically fimbriate with rather short, stout but alternately unequal spinules; superior apical spur shorter than first tarsal segment; latter almost as long as following three combined. Male: punctation of pronotum and elytral intervals relatively less coarse and less dense; metasternal plate weakly excavate, coarsely irregularly punctured and pubescent toward lateral margins; aedeagus Fig. 38-39 View Figure 33-42 . Female: punctation of pronotum and elytral intervals relatively more coarse and more dense; metasternal plate almost flat, finely, sparsely irregularly punctured.
