[1] Broun originally described this species as follows: Elongate, sub-cylindrical, rather depressed, of a glossy reddish-black, with dark-red legs and antennae, and rufescent tarsi and palpi.

Head rather small, having two inter-antennal punctiform impressions, and two oblique furrows proceeding from the antennae and becoming confluent in front of the base.

Prothorax oblong, very slightly rounded laterally, its base almost rounded; two more or less curved broad grooves proceed from the base, where they are foveiform, and terminate near the apex in a large depression occupying the space between the sides, the intermediate dorsal space is indistinctly impressed longitudinally and depressed anteriorly.

Elytra a little narrower than the thorax, with porrected tubercular shoulders, and a deep oblong scutellar depression; the sutural space is rather flattened and well limited by two broad grooves proceeding from the base and uniting at the apex, another similar furrow extends from each shoulder but does not attain the apex; otherwise they are without impressions of any kind.

Legs robust; the anterior tibiae of normal structure, the intermediate and posterior terminate inwardly in a large dentiform protuberance, below which the small spurs are inserted.
