Diagnosis.

4.3-4.9 mm long (mean = 4.5 mm; n = 5); 1.88-1.96 × as long as wide. This species is distinguished by the mesonotal mycangial tuft the length of the scutellum; elytral disc convex; declivity obliquely truncate with lateral margins obliquely costate; declivity opalescent and unarmed; declivital striae not impressed; body stout and densely covered by erect dark brown pubescence.

Similar to Cnestus mutilatus and Hadrodemius species but declivity less steeply truncate, with posterolateral margins rounded, never carinate, procoxae contiguous and the mesonotal mycangial tuft the length of the scutellum.
