Diagnostic description
Holotype, male (Fig. 42a). Length 2.49 mm. Color of antennae light ferruginous; legs and rostrum dark ferruginous; remainder black with bronze luster. Body subglobose; in dorsal aspect with distinct constriction between pronotum and elytron; in profile dorsally convex. Rostrum dorsally with distinct median carina and pair of submedian ridges; intervening furrows each with row of erect, clavate scales; epistome short, subglabrous, indistinct. Pronotum laterally with marked subapical constriction; disk coarsely punctate; interspaces subglabrous, reticulate; with subglabrous median costa. Elytra with basal margin subangulate; densely punctate with coarse punctures, especially near base where punctures partly confluent; interspaces subglabrous; each puncture with suberect to subrecumbent, weakly clavate, scale. Femora edentate; anteroventral ridge distinct; anterior surface rugose-punctate, microgranulate, dull, with sparse subrecumbent scales. Metafemur dorsally denticulate; subapically with stridulatory patch. Metatibia with dorsal edge denticulate; ventrally with fringe of sparse setae. Abdominal ventrites 1–2 concave, subglabrous, sparsely punctate, with sparse suberect scales; ventrite 5 flat, densely coarsely punctate, with suberect slender scales. Penis (Fig. 42b) with sides of body subparallel, slightly widening before weakly extended apex; apodemes 2.9 × as long as body of penis; transfer apparatus complex, asymmetrical; ductus ejaculatorius with distinct bulbus. Intraspecific variation. Length 2.18–2.49 mm. Female rostrum dorsally flattened, with ridges less distinct; with median costa and pair of submedian costae less distinct, anteriorly separated by row of punctures.
