Holotype, male (Fig. 41a). Length 2.63 mm. Color of antennae and tarsi ferruginous; remainder black. Body subovate; in profile dorsally convex. Rostrum dorsally with median carina and pair of submedian ridges; intervening furrows with sparse rows of elongate suberect scales. Pronotum with disk punctate with minute punctures; interspaces between punctures subglabrous. Elytra irregularly punctate with minute punctures; basal margin bordered by transverse row of deeper punctures, continuing laterad along humerus; stria 8 near humerus with five large punctures. Femora edentate. Meso- and metafemur with anteroventral ridge crenate. Metafemur with anterior surface coarsely punctate, reticulate, each puncture with elongate silvery scale; with dorsoposterior edge denticulate; subapically with stridulatory patch.
