Shell of rather small size for genus, adult size of holotype 6.7 mm; fusiform, elongate. Suture slightly incised, whorls shouldered. Protoconch paucispiral, 1.75 smooth whorls. Teleoconch of slightly more than five whorls. Axial sculpture absent. Spiral sculpture of basal cords, ventrally ranging to adapical end of parietal callus. Outer lip thickened, with distinct rim, smooth, bearing only continuation of basal cords. Inner lip denticulate, with six strong, equally spaced denticles. Columellar callus thin. Parietal callus thin. Columella smooth. Siphonal canal short, open, slightly recurved. Teleoconch whorls pale brown in colour with randomly placed off-white to beige flecks. Protoconch reddish-orange. Aperture and columella off-white to beige.

The species is similar to Mitrella scapula and M. debitusae, but differs from M. scapula in its fewer teleoconch whorls, broader overall appearance, less shouldered whorls, higher extension of the basal cords, shorter siphonal canal, and colour pattern. It differs from M. debitusae in the higher extension of the basal cords, the less shouldered whorls, the broader protoconch, the absence of teeth on the columella, the thinner columellar callus and the colour pattern.

New Caledonia, east coast off Hienghène.
