Redescription. Length 3.5-4.5 mm; elongate, subcylindrical, convex, shiny, glabrous. Piceous; clypeal margin, pronotal sides and elytral apex paler; legs brownish-red; antennal club yellowish. Head with epistome smooth, almost flat, dually punctured; few large punctures, twice to three times larger than small ones, irregularly scattered only distally; small fine punctures subregularly sparse throughout, somewhat superficial on disc; clypeus almost truncate anteriorly, round at sides, laterally straight, thinly bordered, edge feebly upturned, glabrous; genae round, very shortly bristled, not protruding from the eyes; frontal suture almost obsolete; front dually irregularly punctured, small punctures finer than those on epistome. Pronotum weakly transverse, convex, dually punctured; large punctures, five to seven times larger than small ones, irregularly sparse on sides but lacking near lateral margins as well as on disc; extremely fine small punctures, regularly sparse throughout, somewhat denser and coarser on sides; lateral margins feebly arcuate, distinctly bordered, edge glabrous; hind angles obtusely round; base bisinuate. Scutellum slightly convex, with a striola along lateral margins, nearly imperceptibly punctured. Elytra convex, elongate, parallel-sided, distinctly striate; striae fine, superficially punctured, faintly crenulate; interstriaealmost flat, withextremely fine sparse punctures, apicallydistinctly microreticulate thus rather dull. Hind tibiae superior apical spur shorter than first tarsal segment; latter as long as following four segments combined. Male: metasternal plate microreticulate, weakly shiny, somewhat more densely punctured; median longitudinal groove foveolate anteriorly; aedeagus Fig. 109-110 . Female: metasternal plate smooth, somewhat more sparsely punctured; medianlongitudinal groove not foveolate.
