DESCRIPTION

Body 7.78­8.01 mm in length, 4.46­4.65 mm in width, from piceous to black.

Head with dorsal surface impunctate; clypeus subapically without a pair of setigerous punctures; each paraclypeus submarginally with a single preocular setigerous puncture; ocular index 2.20­2.21; length of antennal segments (in mm): 0.36: 0.44: 0.45: 0.56, 5 th missing.

Anterior half of pronotal disc impunctate except for few scattered small punctures laterally and behind head; transverse discal impression behind calli absent; posterior half of disc with scattered small punctures; lateral margins of pronotum with 6 submarginal setigerous punctures bearing long hair­like setae. Anterior convexity of propleuron impunctate, except for a patch of small punctures; posterior convexity virtually impunctate; propleural depression with a few punctures.

Puncturation of scutellar disc sparse, especially well visible in apical third; punctures a little larger than those of pronotum.

Mesocorium almost evenly punctate; exocorium with punctures finer than those of scutellum; costa somewhat flattened, with a single setigerous puncture bearing long hair­like seta.

Legs unicolorous; male tibiae with weak basal emargination followed by 5­7 very small denticles; female hind tibiae simple.
