Head dorsally at first sight looking impunctate, but bearing a few small punctures in lateral parts; clypeus subapically without a pair of setigerous punctures, each paraclypeus submarginally with 2­3 setigerous punctures bearing long hair­like setae (Fig. 211); ocular index 2.17­2.40; interocellar index 6.0­6.3; length of antennal segments (in mm): 0.37­0.47: 0.55­0.69: 0.60­0.67: 0.76­ 0.94: 0.90­1.08.

Puncturation of pronotal disc weak, punctures irregularly scattered, better visible behind head and in shallow transverse impression behind calli; lateral margins of pronotum with 6 submarginal setigerous punctures bearing long hair­like setae (Fig. 210). Anterior convexity of propleuron alutaceous, punctate laterally and apically, posterior convexity distinctly coarsely punctate with large punctures, propleural depression coarsely punctate.

Scutellar disc with almost evenly spaced punctures as large as those on pronotum, apex and basal fifth of scutellar disc impunctate.

Punctures on corium distinctly smaller than those on scutellum; clavus with one complete and two partial rows of punctures; mesocorial disc densely and almost evenly punctate; exocorium densely punctate; costa narrow, flattened, separated from exocorium only in its basal half, costal margin with 2 setigerous punctures (Fig. 210).
