Female head bluntly triangular, widest across eyes. Antennomere 1 approximately 1.5 times longer than wide, 2 longer than wide, 3 subquadrate, 4–7 longer than wide, 8–10 subquadrate. Frontal sulcus deep, reaching midpoint of eye. Anterior frontal fovea round and partially covered by frontal rostrum, posterior frontal fovea round. Eye prominent, approximately one-half length of temple. Temporal lobe of male head projecting forward posterior-laterally with weakly concave ventral surface (Fig. 69h). Ventral surface of male head with transverse process behind mouthparts and round depression bearing 3 patches of dense setae (Fig. 69h). Thorax: Prosternum as long as wide, widest at one-third length. Male elytra rectangular (Fig. 68h), female elytra subquadrate.
