Diagnosis. Dorsal surface, pronotal hypomera, and anterior faces of profemora and protibiae bearing elliptical or elongate-pointed white scales; surface of clypeus, pronotum, and scutellum without long, backwardly directed setae; labrum deeply excavated anteriorly; antennae of males with antennomeres 4–10 or 5–10 lamellate; clypeus with anterior face moderately deep, greatest width 5.5–7.5 times mid depth, outline broadly rounded, usually slightly depressed in middle of anterior edge; upper surface of clypeus strongly concave; protarsal claws with a prominent tooth; anterior edge of metafemur not concave near base; lower spur of metatibiae narrow, thick and tapered, upper spur broadly expanded.
