Female head bluntly triangular, widest across eyes. Antennomere 1 approximately 1.5 times longer than wide, 2–5 longer than wide, 6–10 subquadrate. Frontal sulcus deep, reaching midpoint of eye. Anterior frontal fovea round, partially covered by frontal rostrum, posterior frontal fovea round. Eye large and prominent, approximately one-half length of temple. Temporal lobe of male head projecting and exceeding eye, with flattened ventral surface ( Fig. 69k View Fig ). Ventral surface of male head with triangular setose process behind mouthparts ( Fig. 69k View Fig ). Thorax: Prosternum as long as wide, widest at one-third length. Elytra subquadrate ( Fig. 68k View Fig ). Meso- and metathorax trapezoidal, as long as wide. Abdomen: Male tergite IV with pair of small round patches of microtrichia reaching middle, patches absent in female.
