Clypeus and frons with round punctures each with a central seta; antennae reaching midpoint of lateral margin of pronotum; antennomere 9 longer than wide, with apical tomentose sensory patches arranged in two areas separated dorsally; antennomere 10 as wide as antennomere 11. Thorax. Pronotum widest behind midpoint; disc glabrous or with setae, lateral quarters with fine, golden setae; punctures of disc same size as punctures of elytron; width of anterior margin not exceeding half the width of posterior margin; lateral quarters convex, dorsal surface of lateral margin bearing a row of short golden setae; posterior angles acute, apex pointed; prosternum horizontal, with edge on anterior margin broadened below gula; prosternal process produced backwards, not reaching the midpoint of the space between pro– and mesocoxae (as in Fig. 13 ); prosternum and mesosternum with punctures. Elytron lacking carinae and grooves; dorsal surface with short, golden setae; pseudopleuron with long setae arising on punctures; epipleuron with short setae arising on protuberances, with a row of setae on the edge of anterior quarter. Legs. Ventral surface of meso– and metafemora with a row of setae on posterior edge. Inner surface of meso– and metatibiae with long, fine setae. Metatibiae straight. Female genitalia. Paraprocts moderate (1.2 ≤ P/C ≤ 2.0); baculi of coxite inclined 45°; proctigeral baculus extending proximad much beyond paraproct baculus; apicodorsal lobe of proctiger extending about ¼ length of coxite. Male: unknown.
