Redescription. Length 3.5-5.0 mm; oblong, convex, weakly shiny; pronotum pubescent before hind angles, elytralinterstriae with double row of recumbent hairs. Rufo-testaceous; head and pronotum somewhat darker medially; legs reddish-brown; antennal club brownish. Head with epistome feebly convex, evenly regularly punctured throughout; punctures veryfine and sparse; clypeus faintlysinuate at middle, roundat sides, verythinly bordered, edge slightly upturned, glabrous; genae round, elongately sparsely ciliate, not protruding from the eyes; frontal suture distinctly impressed; front somewhat more irregularly puncturedthan epistome. Pronotum moderately transverse, convex, with patch of recumbent pubescence near posterior angles; dually punctured; large punctures, five to six times larger than small ones, coarser and denser on sides, lacking on disc; small fine punctures regularly scattered throughout, somewhat more coarser on sides; lateral margins feebly arcuate, rather thickly bordered, edge fimbriate with sparse elongate setae; hind angles obtusely round; base regularly arcuate, thinly bordered. Scutellum somewhat convex medially, microreticulate, irregularly punctured. Elytra elongate, almost parallel-sided; epipleural carina fimbriate withmoderately elongate setae; striae fine, superficially punctured, not crenulate; interstriae flat, alutaceous, with double longitudinal row of small, rough punctures; each puncture bearing a rather shortrecumbent hair. Hind tibiae superior apical spur not spatulate, somewhat shorter than first tarsal segment; latter longer than following three segments combined. Male: pronotum somewhat more transverse and less convex; metasternal plate more deeply grooved medially and moderately incavate posteriorly; aedeagus Fig. 59-60 . Female: pronotumsomewhat narrowed frontwardly; metasternal plate less deeply grooved medially, not incavate posteriorly.
