Redescription. Length 2.5-3.0 mm, oblong, convex, weakly shiny; glabrous. Testaceous; legs somewhat paler; antennalclub yellowish. Head with epistome feebly convex on disc, almost evenly, finely and rather sparsely punctured; clypeus slightly sinuate at middle, round at sides, very finely bordered, edge near faintly bristled and somewhat upturned; genae round, almost imperceptibly ciliate, not protruding from the eyes; frontal suture distinctly impressed; front more densely and coarsely punctured than epistome. Pronotum weakly transverse, moderately convex, superficially microreticulate, dually, almostregularly punctured; large punctures, three times larger than small ones, somewhat sparser on disc; lateral margins finely bordered, border glabrous; hind angles obtusely round; base feebly bisinuate, Scutellum narrow, elongate, subpentagonal, with curved lateral margins, flat, very finely sparsely punctured on basal half. Elytra elongate, subparallel-sided; striae rather wideand deeply impressed, superficiallypunctured, not crenulate; interstriae finely microreticulate thus weakly shiny, feebly convex on disc, somewhat more convex on sides, finely sparsely punctured. Hind tibiae superior apical spur distinctly shorter than first tarsal segment; latter nearly as long as following three segments combined. Male: fore tibiae apical spur somewhat stouter and morebent downward, third distal tooth angulately widened proximally ( Fig. 118 ); metasternal plate moderately incavate, distinctly sparsely somewhat irregularly punctured, with deep longitudinal groove; aedeagus Fig. 120-121 . Female: fore tibiae apical spur somewhat slender and feebly bent downward, third distal tooth normally shaped; metasternal plate almost flat, nearly imperceptibly punctured, with feeble longitudinal groove.
