Taxonomic history

Xyleborus ursulus Eggers, 1923: 173.

Anisandrus ursulus (Eggers): Dole and Cognato, 2010: 527.

Diagnosis

4.3−4.9 mm long (mean = 4.5 mm; n = 5); 1.88−1.96 times as long as wide. This species can be 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 scutellum visible, declivity less steeply truncate, posterolateral carinae absent, procoxae contiguous, and the mesonotal mycangial tuft the length of the scutellum.
