Color black (Fig. 83); head yellow with black clypeal apex; pronotum with lateral 1/4 yellow; venter black except mouthparts, legs yellow; epipleuron brown medially; abdomen brownish yellow. Head with punctures concealed in alutaceous sculpture; pronotal punctures small, separated by less than to twice a diameter; elytral punctures slightly larger than on pronotum, separated by less than to 3 times a diameter; prosternal punctures large, separated by less than a diameter; mesosternal punctures as large as on prosternum, separated by a diameter or less; metasternal punctures as large as on mesosternum, separated by less than to 3 times a diameter, absent in lateral 1/3; abdominal ventrites 1, 2 with coarse punctures separated by a diameter or less; ventrites 3–4 with fine punctures separated by less than a diameter; ventrite 5 with dense, fine punctation. Head with frons parallel sided, 1.2 times width of eye, apex widely emarginate, lateral angle abruptly rounded (Fig. 84); eye canthus long, about 3/4 width of eye. Prosternum with lateral carina on each side straight, extended from apex of intercoxal process 1/3 distance to apex of prosternum. Epipleuron strongly descending externally. Postcoxal line on basal abdominal ventrite evenly curved, extended 7/8 distance to rear margin of ventrite. Genitalia with basal lobe as long as paramere, basal 3/4 parallel sided, apical 1/4 narrowed to rounded apex; paramere robust, curved, apex rounded (Fig. 85, 86); penis with apex shortly attenuate; basal capsule slender, inner arm short, curved, apex acute, outer arm tapered from base to abruptly rounded apex (Fig. 87).
