Length 2.5-3.5 mm ; oblong, convex, moderately shiny, elytra very shortly pubescent. Reddish brown; epistome, pronotal disc, lateral margins of scutellum, elytral suture and sometimes also elytral disc, darkened; legs reddish brown with tarsi somewhat paler; antennal club pale testaceous. Headwith epistome gibbous, simply, rather denselyregularly andmoderately coarsely punctured; clypeus distinctly sinuate at middle, round at sides, thinly bordered, edge glabrous, somewhat reflexed anteriorly, lateral margins almost straight; genae obtusely round, glabrous, feebly protruding from the eyes; frontal suture finely impressed, not tuberculate; front evenly, almost coarsely, not closely punctured. Pronotum transverse, convex, simply, rather densely regularly andmoderately coarsely punctured; punctationsomewhat denser on sides; lateral margins subparallel toward the base, thinly bordered, edge glabrous; hind angles obliquely subtruncate; base feebly bisinuate, distinctly bordered, edge sometimes with few short hairs at scutellum level. Scutellum narrow with lateral margins arcuate, sparsely coarsely punctured. Elytra oval elongate, subdenticulate at shoulder; epiplerural carina shortly bristled toward shoulder; striae rather fine, feebly crenulate, wider toward apex; interstriae strongly convex, almost roof-shaped, finely serially punctured laterally; each puncture shortly recumbently pubescent.
