Description. Length 7.8–9.2 mm, width 3.8–4.2 mm. Dark brown to black, dorsal surface glabrous, shiny. Head transverse, coarsely punctate, denser on clypeus; gena strongly punctate, genal groove long ( Fig. 12 ); antenna reddish brown. Pronotum somewhat convex, margins beaded, lateral margins weakly bisinuate, widest at middle, anterior margin slightly elevated and weakly sinuate medially, bead fading medially, anterior angles rounded, basal marginal bead fading medially, basal angles obtuse, surface moderately punctured, shagreened between punctures at higher magnification; hypomeron glabrous, impunctate, and shagreened; prosternum medially longitudinally raised, bearing pits with golden seta, margined between coxae and behind, prosternal process with a raised, smooth lateral margin between coxae to posterior apex, median disc not depressed and without groove, bearing fine, golden setae ( Fig. 12 ). Elytron with deep, fine striae with small punctures; 1 st and 2 nd striae converging anteriorly always joined, interstriae convex and sparsely finely punctate, glabrous, surface shagreened. Mesoventrite with higher concentration of shallow, setose punctures in mesoventral cavity; metaventrite nearly impunctate, punctures shallow and disperse, without post-coxal, pit-like crenulations. Tibiae with sparse microsetae on dorsal surface, apical third of ventral surface with erect, golden setae, becoming dense, golden brush at apex.
