Head dorsally slightly wrinkled, at first glance looking impunctate, but bearing numerous hardly visible tiny punctures; clypeus subapically without a pair of setigerous punctures, each paraclypeus submarginally with 6­8 (usually 7) setigerous punctures bearing long hair­like setae (Fig. 218); ocular index 2.42­ 2.75; interocellar index 10.0­16.0; length of antennal segments (in mm): 0.20­ 0.28: 0.22­0.33: 0.26­0.35: 0.33­0.39: 0.35­0.43.

Pronotal disc distinctly punctate in its anterior and lateral parts and behind calli; transverse discal impression absent; lateral margins of pronotum with 7­9 submarginal setigerous punctures bearing long hair­like setae (Fig. 217). Anterior convexity of propleuron impunctate, posterior convexity impunctate except for a few punctures, propleural depression coarsely punctate.

Scutellar disc densely punctate with punctures larger than those on pronotum, anterolateral angles and apex impunctate.

Mesocorial disc entirely evenly punctate; exocorium densely punctate; costa narrow, almost entirely separated from exocorium, bearing 4­6 setigerous punctures (Fig. 217).
