Head large, distinctly wider than anterior pronotal margin; frontoclypeus widely, shallowly emarginate; frons flat with shallow, rounded, medial impression; vertex flat, 5 times as wide as width of eye; eyes relatively small, elliptical, rather strongly projecting beyond outline of head; antennae slender, reaching posterior third of lateral pronotal margins when laid alongside; scape very slender, slightly curved, 6 times as long as wide; pedicel small, ovoid, 1.8 times as long as wide; third antennomere small, slightly claviform, 1.6 times as long as wide; antennomeres 4–10 obtusely triangular, 1.2–1.8 times as long as wide; terminal antennomererhomboid, 1.8 times as long as wide; sculpture consisting of small, very dense, oval or rounded cells without central grains which are larger and more prolonged in frontal impression, smaller and rounded on remainder of head. Pronotum strongly convex, nearly bell-shaped, 1.9 times as wide as long; lateroposterior depressions nearly indistinct; anterior margin shallowly biarcuate, posterior margin nearly straight; lateral margins straight, tapering anteriorly at anterior half, regularly arched at posterior half; posterior angles nearly rectangular; maximum pronotal width at base; sculpture consisting of small, dense, rounded cells without central grains on anterior half; prescutellar portion with rather rough, long, transverse rugae, posterior angles with short, transverse rugae. Scutellum widely pentagonal, slightly impressed medially, 2.5 times as wide as long. Elytra regularly, strongly convex, 1.8 times as long as wide with maximum width at posterior third, slightly caudiform; humeral swellings well-developed; basal, transverse depression short, wide, not reaching scutellum; elytral epipleura narrow, reaching posterior third of elytral length; posterior third of elytral margins weakly serrate; each elytron with eight fine striae; interstices with fine, short, transverse rugae at posterior half; basal half of elytra with rough, deep, transverse rugae. Ventral surface rather lustrous, finely ocellate, prosternum roughly ocellate; prosternal process very weakly convex, obtusely pointed apically, not enlarged posteriad procoxae; anal ventrite apically obtusely rounded, without lateral serration. Legs relatively long, slender; meso- and metatibiae finely bent outwards at posterior half. Claws slender, hook-shaped, slightly enlarged at base. Aedeagus (Fig. 10) short, flat, nearly spatulate, parameres subparallel at basal half, slightly enlarged and regularly rounded towards apex at posterior half; median lobe simply pointed apically. Sexual dimorphism. Except for the colouration (see above) female differs from male only by more robust and larger body. Variability. Pronotum 1.9–2.1 times as wide as long; elytra 1.7–1.9 times as long as wide. No variability in colouration was observed in males; several female paratypes possesses darker lateral portion of elytra (nearly black with slight metallic tinge) and darkened medial portion of pronotum (black with intensive blue-green tinge). Measurements. Length 6.7–10.1 mm (holotype 8.0 mm); width: 2.6–4.0 mm (holotype 3.0 mm).
