Holotype, male (Fig. 99a). Length 3.17 mm. Color orange-ferruginous; dorsal surface of head and pronotum black. Body subrhomboid, almost without constriction between pronotum and elytron; in profile evenly convex. Rostrum with distinct median and pair of submedian carinae, furrows containing sparse rows of mesad-directed scales. Pronotum densely punctate. Elytra with striae 1–6 distinct, marked by dense rows of small punctures, intervals with minute punctures; lateral striae obsolete; sides with sparse, confused punctures. Femora edentate; anteroventral ridge terminating at middle with inconspicuous denticle. Metafemur with crenulate dorsoposterior edge; subapically with stridulatory patch. Protibia with relatively long uncus. Metatibia apically with uncus and premucro, in apical 1/3 dorsal edge with 4–5 large setiferous punctures. Ventrite 5 densely punctate, medially with broad impression. Aedeagus (Fig. 99b) with apex medially pointed; ostium with intensely-sclerotized asymmetrical sclerite and connected to it with pair of two elongate undulating sclerites reaching far into endophallus; flagelliform transfer-apparatus longer than body of aedeagus; ductus ejaculatorius with bulbus. Intraspecific variation. Length 2.72–3.28 mm. Female rostrum dorsally in apical half subglabrous, with submedian rows of punctures. Impression of female abdominal ventrite 5 less marked.
