Diagnostic description
Holotype, male (Fig. 32a). Length 1.98 mm. Color black, antenna and tarsi ferruginous. Body laterally somewhat compressed; ovate; without constriction between pronotum and elytron; in profile almost evenly convex. Rostrum dorsally in basal half with pair of sublateral furrows; medially even, sparsely punctate. Eyes large. Pronotum subglabrous. Elytra subglabrous, laterally sparsely punctate with small punctures, striae indistinct. Femora with anteroventral ridge. Profemur subparallel. Meso- and metafemur with dorsoposterior edge subapically worn; metafemur subapically without stridulatory patch. Tibiae simple, without rows or brushes of long setae. Metaventrite laterally forming acute process over metacoxa, reaching tibial insertion. Metaventrite and abdominal ventrite 1 subglabrous, with sparse recumbent setae. Abdominal ventrite 2 fused to and forming common cavity with ventrite 1. Abdominal ventrite 5 anteriorly with pair of distinct longitudinal protrusions, indistinct median cavity posteriorly open. Aedeagus (Fig. 32b) apically with median extension and with pair of submedian teeth; body with two conspicuous pairs of endophallic sclerites; ductus ejaculatorius without bulbus. Intraspecific variation. Length 1.98–2.18 mm. Female rostrum subglabrous except in basal ¼ with ridges. Female abdominal ventrite 5 flat.
