Clypeus rounded laterally, straight mesally, constricted above antennal bases, with very distinct marginal bead. Clypeus and frons with uniform punctuation consisting of semicircular punctures, bearing a very fine seta each (seen only under SEM), interstices without microsculpture.

Mentum with sparsely arranged fine setiferous punctures, those situated on lateral margin and close to it with stouter and longer setae; interstices with strong scale-like microsculpture. Antennal club with distinct groups of peg-like sensilla situated ventrally on distal margin of antennomeres 7 and 8 and in two oval closely adjacent groups in apical third of antennomere 9, the sensilla are intermixed with surrounding setae, not placed in a deep cavity. Maxilla of male with sucking disc ventrally.
