Redescription. Length 7.0 mm. Body, antennae and legs dark brown. Head. Clypeus and frons with round punctures each with a central seta; antennae reaching 3/4 along 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 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 row of short golden setae; posterior angles right, apex rounded (Fig. 26); 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 grooves, with two carinae weakly defined, equidistant between suture and lateral margin (Fig. 26); dorsal surface with short golden setae; pseudopleuron with long setae arising on punctures; epipleuron with short setae arising on protuberances, lacking 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. 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 “inverted V”-shaped ventrally, widest at base, with sparse setae on distal 1/5 of ventral surface. Median lobe moderate (0.75
