Diagnostic description

Holotype, male (Fig. 7a). Length 2.63 mm. Color black; antenna light ferruginous; tarsi and tibiae deep ferruginous. Body subovate-hexa-goniform; in dorsal aspect with shallow constriction between pronotum and elytron; in profile evenly convex. Rostrum in basal half with median and pair of submedian carinae; laterally somewhat flattened; with sparse suberect scales; epistome with transverse, angulate ridge. Pronotum with anterior margin curved dorsad, forming lateral angles; disk subglabrous, anteriorly densely coarsely punctate, towards sides forming edges; laterally in front and behind procoxa with cavity. Elytra subglabrous; intervals flat, with minute punctures; striae weakly incised on disk, towards glabrous sides forming edges; interval 7 subapically forming edge, apex angulate. Femora edentate. Metafemur dorsally squamose with indistinct suberect scales; in apical third without transverse row of setae, subapically with stridulatory patch. Aedeagus (Fig. 7b) apically subangulate, median tip truncate; with complex, symmetrical transfer apparatus; ductus ejaculatorius with indistinct bulbus. Intraspecific variation. Length 2.60–2.63 mm. No female specimen available.
