Body 8.43­11.27 mm in length, 4.56­5.88 mm in width, ochraceous to almost black.
Head dorsally with several punctures on paraclypei; clypeus without a pair of subapical hair­like setae, each paraclypeus with a single preocular submarginal setigerous puncture (Fig. 16); ocular index 2.20­3.10; interocellar index 4.8­7.0; length of antennal segments (in mm): 0.39­0.45: 0.53­0.67: 0.60­0.76: 0.78­ 0.98: 0.94­1.04.
Pronotal transverse discal impression behind calli usually conspicuously developed; anterior margin, lateral parts and posterior lobe more or less distinctly punctate; lateral margins with 5­6 submarginal setigerous punctures (Fig. 15). Propleural depression and basal half of posterior convexity distinctly punctate.
Scutellum punctate, except anterolateral angles and apex; punctures of the same size as those on pronotum.
Clavus with one complete and two partial rows of punctures; mesocorial disc almost evenly punctate, punctures almost of the same size as those on pronotum; exocorium with very dense puncturation, punctures smaller than those on mesocorium; costa narrow, almost entirely separated from exocorium, bearing 2 setigerous punctures (Fig. 15).
