Diagnostic description
Holotype, male (Fig. 97a). Length 2.63 mm. Color black, with violet lustre. Body subovate; with weak constriction between pronotum and elytron; in profile evenly convex. Rostrum dorsally relatively flat, sparsely punctate, dorsolaterally with pair of furrows continuing along eye. Pronotum sparsely punctate with minute punctures, subapically punctures larger and denser. Elytra nude, striae deeply impressed with coarse punctures; intervals costate, with sparse minute punctures; intervals 1–3 near base with few larger punctures and coriaceous. Femora edentate. Metafemur subapically with stridulatory patch. Abdominal and thoracic venter with dense erect setae. Aedeagus (Fig. 97b) apically subangulate, with two brushes of long setae; transfer apparatus complex, with flagellum ca. 1.5× as long as body; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.20–2.95 mm. Color ranging from greenish-blue to dark violet. Female rostrum dorsally subglabrous, with punctures smaller than in males. Elytral intervals more or less costate, rarely almost flat.
