Head: Cranium coarsely sculptured, highly setose; antenna ( Fig. 69 View Figs 61-91 ) capitate, funicular antennomeres filiform, progressively shorter towards capitulum, capitular antennomeres 8 and 9 triangular, antennomere 10 ovoid; eyes large, finely facetted, eye slightly narrower than frons (EW/FW 25/28). Thorax: Pronotum ( Fig. 131 View Figs 118-133 ) quadrate, highly setose, somewhat corrugated, disc deeply concave paralaterally near pronotal collar; discal and lateral trichobothria well developed (PW/PL 70/70); elytral disc corrugated; asetiferous punctures large and randomly distributed, small brown and yellow setal wisps present throughout elytral disc (EL/EW 290/55); anterior margin of protibia with 4 spines.
