Diagnostic description
Holotype, male (Fig. 2a). Length 1.91 mm. Color black with greenish-bronze lustre; antenna and tarsi ferruginous. Body subrhomboid; in dorsal aspect and in profile with distinct constriction between pronotum and elytron. Rostrum with weak median wrinkle; epistome simple. Eyes small. Pronotum with weak subapical constriction; disk sparsely punctate. Elytra with strial punctures distinct; intervals flat, subglabrous; interval 7 subapically costate, forming angulate ridge; sutural interval apically with knob. Meso- and metafemur ventrally weakly dentate. Metafemur subapically without stridulatory patch. Onychium ca. 1.8× longer than tarsomere 3. Aedeagus (Fig. 2b) with apex weakly asymmetrical; long median extension somewhat shifted to the left; transfer apparatus hook-shaped; ductus ejaculatorius with indistinct bulbus, torn off in holotype. Intraspecific variation. Length 1.63–1.91 mm. Female rostrum dorsally subglabrous, sparsely punctate.
