Teleoconch of ca. 4.5 whorls. Axial sculpture of strong axial ribs on first 2-2.5 whorls, diminishing in strength on subsequent whorls, obsolete on final two whorls. Spiral sculpture of basal cords, ventrally ranging to adapical end of columella. Outer lip thickened, with distinct rim, smooth, bearing only continuation of basal cords. Inner lip denticulate, with seven equally spaced denticles of equal size. Columellar callus thickened. Parietal callus thinner than columellar callus. Columella with row of merged denticles, forming small rim. Siphonal canal short, open, slightly recurved. Teleoconch whorls off-white in colour, with band of white spots, interrupted by pale yellowish-brown flammules, immediately above and below suture. Protoconch off-white.

Interchangeable taxa

This species is most similar to Mitrella cuspidata, but the latter differs in the lack of axial sculpture, the more shouldered whorls and the more elongate and lighter shell.
