Head – CW / L: 3.4; anterolateral edges of clypeus rounded, lateral edges of clypeus curved divergent posteriad; frons large, making eyes relatively small (F / O: 5.3); frons concave; antennal club longer than antennomeres 2 - 7 (A 2 - 7 / CL: 0.7) (Fig. 21). Pronotum – Transverse (PnW / L: 2.2), strongly convex; apical angles and lateral margins largely flattened, apical angles right not protuberant; basal lateral margins straight, basal angles largely rounded. Elytra – Without visible striae.
