Shell size small for genus, adult size up to ca. 7.7 mm; fusiform, elongate. Suture slightly impressed, whorls slightly shouldered. Protoconch paucispiral, slightly less than two smooth whorls. Teleoconch of slightly more than five whorls. Axial sculpture absent. Spiral sculpture of basal cords, ventrally ranging to just above adapical end of columella. Outer lip thickened, with small rim, smooth, bearing only continuation of basal cords. Inner lip denticulate, with five strong, equally spaced denticles. Columellar callus thickened, slightly demarcated. Parietal callus weak. Columella with three partially merged denticles. Siphonal canal short, open, straight. Teleoconch whorls off-white in colour, with band of faint pale brown flecks across adapical half of whorls. Final whorl with second band of flecks just above basal cords. Protoconch semi-translucent, off-white. Aperture and columella off-white. Holotype height 7.5 mm.

This species is most similar to Mitrella debitusae, but differs in the less shouldered whorls, the more bulbous protoconch, a less constricted siphonal canal, fewer columellar denticles and the colour pattern.
