Head: Antenna ( Fig. 89 ) capitate, 6 th funicular antennomeres slightly expanded, capitular antennomeres 8 and 9 subquadrate, antennomere 10 slightly oblong; eyes large, finely facetted, ocular notch large, eye wider than frons (EW/FW 20/12). Thorax: Pronotum ( Fig. 161 ) transverse (PW/PL 50/40), anterior transverse depression deeply impressed; disc finely punctate, lateral tubercle well developed, disc concave paralaterally near pronotal collar; discal and lateral trichobothria prominent; elytral asetiferous punctures profusely distributed, punctures substriate (EL/EW 160/36); anterior margin of protibia with 6 spines.
