Holotype, male (Fig. 60a). Length 1.54 mm. Antenna, legs, and head ferruginous; pronotum, elytra, and tarsi black. Body subovate; in dorsal aspect and in profile with distinct constriction between pronotum and elytron. Rostrum punctate; epistome simple. Eyes small, anterior margin angularly projecting. Pronotum with weak subapical constriction; disk densely, coarsely punctate; each puncture with short, yellowish scale. Elytra with striae deeply impressed; each puncture with suberect, yellowish scale; intervals subglabrous, costate, partly transversely confluent. Meso- and metafemur ventrally dentate. Metafemur subapically without stridulatory patch. Onychium ca. 1.6× longer than tarsomere 3. Aedeagus (Fig. 60b) with apex asymmetrical, right side forming long curved extension; basal orifice ventrally with rim; transfer apparatus dentiform; ductus ejaculatorius without bulbus. Intraspecific variation. Length 1.46–1.54 mm. Female rostrum slightly longer, dorsally subglabrous, sparsely punctate, in basal third coarsely punctate. Female elytral apex markedly extended ventrad, beak-shaped. Abdominal ventrite 3 of females with flattened process projecting over ventrite 4, medially with bifid extension reaching base of ventrite 5, sublaterally with pair of shorter spines. Female abdominal ventrites 4–5 weakly sclerotized.
