Redescription. Length 3.5-4.0 mm; oval, convex, shiny, glabrous. Dark brown; clypeal margin, base and sides of pronotum, and elytral apex yellowish brown; legs brownish-yellow; antennal club brownish. Head with epistome feebly gibbous on disc, superficially alutaceous, finely evenly, not closely punctured; clypeus anteriorly subtruncate and thickly bordered, widely round and finely bordered at sides, edge glabrous; genae obtusely round, almost glabrous; faintly protruding from the eyes; eyes large; frontal suture extremely fine, obsolete laterally; front evenly sparsely punctured. Pronotum broadly transverse, moderately convex, dually punctured; large coarse punctures, four to five times larger than small ones, irregularly scattered; denser and coarser on sides, much sparser and superficial toward disc and therein lacking; small punctures not closely, evenly sparse throughout, more superficial and sparse medially; lateral margins feebly arcuate, rather finely bordered, edge glabrous; hind angles widely obliquely truncate, truncation feebly sinuate inwardly; base bisinuate. Scutellum rather narrowly elongate, somewhat concave; finely punctured on basal half. Elytra oval, broadened posteriorly, not denticulate at shoulder, finely striate; striae superficially punctured, feebly crenulate; interstriae finely alutaceous, almost flat, nearly imperceptibly sparsely punctured. Hind tibiae upper spur almost as long as first tarsal segment; first tarsal segment longer than following three segments combined.
