); venter yellow; abdomen yellow except median 1/3 of ventrites 1, 2, light brown. Head punctures small, separated by less than a diameter; pronotal punctures as large as on head, separated by less than a diameter; elytral punctures larger than on pronotum, separated by less than to 3 times a diameter, becoming larger, denser toward lateral margin; prosternum with small punctures separated by less than a diameter; mesosternum with punctures larger than on prosternum, separated by about a diameter; metasternum with punctures in median 1/3 as large as on mesosternum, separated by less than to twice a diameter in median 1/3, punctures absent in lateral 1/3; abdomen with ventrites 1, 2 coarsely punctured, punctures separated by about a diameter; ventrites 3, 4 densely punctured; ventrite 5 finely, densely punctured. Head with frons parallel sided, 1.2 times as wide as eye, clypeal apex widely emarginate, lateral angle abruptly curved (
Fig. 95
); eye canthus long, about 3/4 width of eye. Prosternum with lateral carina on each side straight, extended from apex of intercoxal process to about 1/4 distance to apex of prosternum. Epipleuron strongly descending externally. Postcoxal line on basal abdominal ventrite curved, extended 3/4 distance to rear margin of ventrite. Genitalia with penis guide long, basal lobe as long as paramere, sides nearly parallel in basal 2/3, gradually narrowed from base to rounded apex in apical 2/3; paramere weakly sinuate, apex rounded (
Fig. 96, 97
