Head with dorsal surface at first sight looking impunctate, but bearing small, irregularly scattered punctures; clypeus subapically without setigerous punctures, each paraclypeus submarginally with a single preocular setigerous puncture (Fig. 81); ocular index 2.18­2.30; interocellar index 6.7­9.0; length of antennal segments (in mm): 0.38­0.44: 0.54­0.67: 0.65­0.78: 0.85­0.99: 0.97­1.13.

Puncturation of pronotal disc more or less distinct, usually better visible behind calli; transverse discal impression absent; lateral margins of pronotum with 4 (rarely 5) submarginal setigerous punctures bearing long hair­like setae (Fig. 80). Anterior convexity of propleuron more or less punctate, posterior convexity distinctly punctate with irregularly scattered coarse punctures, propleural depression with a row of coarse punctures.

Scutellum with puncturation better visible in its median part.

Mesocorial disc almost evenly punctate with large punctures basally and small punctures apically; exocorium more or less densely punctate; costa narrow, entirely separated from exocorium, basally flattened and bearing two setigerous punctures (Fig. 80).
