 Redescription. Length 4.5–6.0 mm; elongate-oblong, moderately convex, shiny, glabrous. Pale reddish brown; head posteriorly and pronotal disc more or less widely brownish; legs and antennal club pale reddish brown. Head with epistome moderately convex on disc, toward clypeal margin sparsely minutely granulate; finely, rather closely and somewhat irregularly punctured postero-medially; clypeus feebly sinuate at middle, obtusely round at sides, lateral margins arcuate, thinly bordered, edge reflexed and glabrous; genae broadly round, ciliate, not protruding from the eyes; front rather finely, irregularly punctured. Pronotum moderately convex, shallowly depressed near posterior angles, dually punctured; large coarse punctures, ten times or more larger than small, irregularly scattered throughout, denser near hind angles, closer on sides, sparser on disc; small, very fine punctures not closely, evenly sparse throughout; anterior angles broadly round; lateral margins rather subparallel toward base and slightly inwardly sinuate before hind angles, thinly bordered, edge glabrous; hind angles obtusely round, base regularly arcuate, finely bordered. Scutellum distinctly punctured on basal half. Elytra slightly broader posteriorly; striae fine, rather closely punctured, subcrenulate; interstriae almost flat, very finely and sparsely punctured. Hind tibiae upper spur somewhat shorter than first tarsal segment; latter as long as following three segments combined. Male: pronotum relatively less convex, more transverse, more sparsely punctured; fore tibiae spur stout; inferior spur of middle tibiae shortened and obliquely truncate apically; aedeagus Fig. 24–25. Female: pronotum relatively more convex, less transverse, more densely punctured; fore tibiae spur slender; middle tibiae inferior spur acuminate.
