Diagnostic description
Holotype, male (Fig. 20a). Length 3.00 mm. Color black. Body slender, subrhomboid; without constriction between pronotum and elytron; in profile evenly convex. Rostrum in apical third smooth; in basal 2/3 with broad median costa and pair of sublateral ridges; furrows containing sparse row of setae. Eyes with dorsal margin carinate. Head bordering eye with elongate impression. Pronotum subglabrous, sparsely punctate with minute punctures. Elytra subglabrous, punctation confused with minute punctures; striae hardly visible, impressed as very fine lines; lateral stria behind humeri with row of ca. 5 deep punctures. Femora subglabrous, including dorsum of metafemur without scales. Mesofemur on posterior surface with longitudinal ridge. Metafemur on posterior surface with two longitudinal furrows; dorsally with smooth ridge; subapically without stridulatory patch. Meso- and metatibia subapically simple, with uncus, without premucro. Aedeagus (Fig. 20b). Apex symmetrical, with median acute extension; body dorsally with two rows of sparse short setae; transfer apparatus small, dentiform; endophallus without distinct sclerites; ductus ejaculatorius without bulbus. Intraspecific variation. Length 1.95–3.00 mm.
