Redescription. Length 3.0- 4.5 mm; oval-elongate, convex, shiny; head and pronotum glabrous, elytra laterally andtowardapex distinctly pubescent. Reddish-yellow; head, pronotum andelytral suture brownish-red; legs reddish-yellow; antennal club testaceous. Head with epistome feebly convex on disc, evenly finely sparsely punctured throughout; clypeus feebly sinuate at middle, round at sides, not bordered but edge somewhat upturned, glabrous; genae round, sparsely ciliate; faintly protruding from the eyes; frontal suture deeply impressed; front very finely sparsely punctured. Pronotum moderately transverse, convex, dually punctured; large punctures, four to five times larger than small, denser on sides but almost lacking on disc; small fine punctures regularly scattered throughout but lacking on a longitudinal median areola; lateral margins feebly arcuate, thinly bordered, edge elongately sparsely ciliate; hind angles obliquely feebly truncate; truncation somewhat inwardly sinuate; base not bisinuate, thinly bordered. Scutellum flat, sparsely irregularly punctured. Elytra rather elongate, convex, slightly tapered toward apex, very finely striate; striae superficially punctured, weakly crenulate; interstriae very superficially microreticulate, indistinctly sparsely punctured; the tenth interstria pubescent in apical two thirds; the ninth in apical half; all other pubescent from preapical declivity to apical margin and therein more distinctly punctured. Hind tibiae superior apical spur elongate, narrowly spatulate and, in lateral view, very narrowly concave on apical two thirds; first segment of hind tarsi almost as long as superior apical spur of tibiae and as long as following three segments combined. Male: pronotum somewhat more transverse; metasternal plate posteriorly excavate with somewhat more deep median longitudinal groove; aedeagus Fig. 9-10 . Female: pronotumsomewhat narrowed anteriorly; metasternalplate almostflat with superficial medianlongitudinal groove.
