Diagnostic description
Holotype, male (Fig. 2a). Length 2.25 mm. Color of antennae ferruginous, legs dark ferruginous; remainder black, elytra with bronze lustre. Body subovate, in dorsal aspect and in profile with weak constriction between pronotum and elytron. Rostrum with median and pair of submedian ridges, intervening furrows each with sparse row of mesad directed setae; epistome with indistinct transverse, subangulate ridge. Pronotum coarsely punctate, laterally reticulate, submedially interspaces longitudinally rugose, with median costa; with sparse, suberect setae. Elytra with striae deeply impressed; each with sparse row of slender suberect scales; intervals costate, subglabrous; sutural interval with few coarse punctures. Femora with simple, crenate anteroventral ridge. Metafemur subapically with stridulatory patch. Metatibia apically with uncus, without premucro. Abdominal ventrite 5 coarsely punctate, with sparse subrecumbent setae, with indistinct median ridge. Penis (Fig. 2b) with sides of body subparallel; containing pair of sclerites; apex sparsely setose, with median, subtriangular extension; transfer apparatus symmetrical; apodemes 2.4 × as long as body; ductus ejaculatorius without bulbus, basally forming distinct loop, entering transfer apparatus from apically. Intraspecific variation. Length 1.90–2.24 mm. Color with bronze lustre more or less distinct; sutural interval ferruginous or black. Female rostrum in apical half dorsally subglabrous, punctate; epistome simple. Elytra with coarse punctures of sutural interval confined to base or passing middle.
