Head dorsally at first glance looking impunctate, but bearing hardly visible tiny punctures; clypeus without subapical setigerous punctures, each paraclypeus submarginally with a single preocular setigerous punctures (Fig. 259); ocular index 2.00­2.40; interocellar index 8.0­12.0; length of antennal segments (in mm): 0.31­0.42: 0.40­0.49: 0.49­0.65: 0.63­0.80: 0.68­0.92.

Pronotal transverse impression behind calli more or less shallow, with a row of punctures interrupted medially; lateral margins with 5­8 submarginal setigerous punctures bearing long hair­like setae (Fig. 258); puncturation of anterior and posterior lobe of pronotal disc clearly visible. Propleural depression and basal part of posterior convexity with numerous punctures, anterior convexity alutaceous.

Scutellum with numerous irregularly scattered punctures, apex and anterolateral angles impunctate.

Corium with distinct punctures smaller than those on pronotum and scutellum; clavus with one complete and one or two partial rows of punctures; mesocorial disc almost evenly punctate; costa narrow, moderately convex, almost entirely separated from exocorium, bearing 2­4 setigerous punctures (Fig. 258).
