Puncturation of two series: larger, coarser series evenly spaced, with interstices as wide as diameter of one puncture; smaller, fine series near postero-medial margin, irregularly scattered, one-fourth as wide as larger series. Anterior margin curving inwards on both sides from antero-lateral angle, with deepest point on 0.2 laterad and curving outwards mediad. Lateral margins slightly curved, without setae. Postero-lateral angle ca. 70-80°. Posterior margin almost straight with curvature laterad. Prosternum flat. EL/EW = 1.13; EL/PL = 4.13; EW/PW = 1.11; TL/EW = 1.69. Elytra black, with very narrow brown lateral margins and posterior area; setae absent. Shoulder regions not accentuated. Punctures coarse, strongly impressed especially near the disc, arrangement dense, spacing as wide as punctures near the disc, wider than punctures laterad; depressions or rows of coarser punctures on lateral portion absent.
