Holotype, male (Fig. 46a). Length 2.58 mm. Color of antennae and tarsi ferruginous; remainder black. Body subovate; in dorsal aspect with weak constriction between pronotum and elytron; in profile dorsally convex. Rostrum dorsally with median costa and pair of submedian ridges; intervening furrows each with row of subrecumbent setae. Pronotum with disk densely punctate; interspaces between punctures subglabrous, subequal to or smaller than punctures´ diameter. Elytra with striae marked by fine lines and rows of small punctures; basal margin bordered by transverse row of deeper punctures; stria 8 along humerus with six larger punctures, externally bordered by costa; sutural interval with additional row of small punctures, other intervals subglabrous, with few interspersed punctures. Femora edentate; anteroventral ridge of mesofemur and metafemur crenate; anterior surface coarsely punctate, each puncture with recumbent narrow scale. Metafemur with dorsoposterior edge denticulate; subapically with stridulatory patch. Metatibia subapically near tarsal articulation with dense cluster of strongly incurved setae. Abdominal ventrites 1–2 concave, subglabrous; ventrite 5 with apical 1/2 bent ventrad; sparsely punctate. Penis (Fig. 46b) with sides of body concave, widening to apex; with ostium protruding over ventral rim of penis, without setae; apodemes 2.2 × as long as body of penis; transfer apparatus complex; ductus ejaculatorius without bulbus.
