Puncturation of pronotal disc clearly visible, punctures larger than those on head; calli and posterior margin impunctate; transverse discal impression behind calli absent; lateral margins of pronotum with 4­5 submarginal setigerous punctures bearing long hair­like setae (Fig. 295). Anterior convexity of propleuron alutaceous, anteriorly and laterally coarsely punctate with small punctures; posterior convexity alutaceous, with numerous large punctures; propleural depression with large and coarse punctures.

Scutellum almost evenly punctate, punctures almost of the same size as those on pronotum; antero­lateral angles impunctate.

Clavus with one complete and two partial rows of punctures; mesocorial disc almost evenly punctate, all punctures distinctly smaller than those on scutellum; exocorium distinctly punctate, punctures of the same size as those on mesocorial disc; costa narrow, entirely separated from exocorium, costal margin with a single setigerous puncture bearing long hair­like seta (Fig. 295).
