Redescription. Length 5.0–9.0 mm. Body black to dark brown, antennae and legs dark brown. Head. Clypeus and frons with round punctures each with a central seta; antennae reaching midpoint of lateral margin of pronotum; antennomere 9 wider than long, with apical tomentose sensory patches arranged in two areas close dorsally; antennomere 10 wider than antennomere 11. Thorax. Pronotum widest behind midpoint; disc and lateral quarters with fine golden setae; punctures of disc same size as punctures of elytron; width of anterior margin exceeding half the width of posterior margin; lateral quarters convex, dorsal surface of lateral margin bearing a tuft of long golden setae; posterior angles right, apex rounded; prosternum horizontal, with edge on anterior margin broadened below gula; prosternal process subrectangular forming a right angle, not produced backwards (as in Fig. 12); prosternum and mesosternum with protuberances. Elytron lacking carinae, with three grooves bearing short, broad, golden, scaly setae, intervals arched, wider than grooves; dorsal surface with short golden setae; the inner groove runs from apex of elytron surpassing the midpoint of elytron towards anterior, converging at the apex with the inner groove of the other elytron, the medial groove runs from apex of elytron reaching the base towards anterior, sometimes interrupted, the outer groove runs over lateral margin from apex of elytron reaching the base towards anterior; pseudopleuron with long setae arising on protuberances; epipleuron with short setae arising on protuberances, bearing 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 curved outward. Male genitalia. Rods of sterna IX close to each other at basal third. Basal lamina of tegmen equal width throughout, with base concave. Lateral styles of tegmen with proximal margin ventrally concave, widest at base, with setae on distal 1/5 of ventral surface (Fig. 7). Median lobe moderate (0.75 <L/T ≤ 1.00), equal width throughout, with apical aperture small and apex acute (Fig. 6). Female genitalia. Paraprocts long (2.0 <P/C ≤ 3.0); baculi of coxite horizontal; proctigeral baculus equal to length of paraproct baculus; apicodorsal lobe of proctiger extending about ¼ length of coxite.
