Shell of moderate size for the genus; fusiform, elongate, with slightly rounded whorls. Suture slightly impressed. Protoconch multispiral, about 4 whorls with close-set axial ribs. Transition to teleoconch clearly visible. Teleoconch with about 4 whorls. Axial sculpture of strong ribs on all whorls, interspaces between ribs as wide as the ribs. About 20 ribs on each whorl. Spiral sculpture seems to be absent on first teleo-conch whorls, but cleary present on the body whorl, consisiting of about 20 weak, close-set spiral cords (basal cords not included). The basal cords ventrally range up to the adapical end of the columella. Outer lip thickened on the outside, bearing continuation of the spiral sculpture and basal cords. Inside of the outer lip denticulate, with 11 spiral ribs of which the 5-6 adapical-most show a clear denticle near the edge of the aperture. Posterior canal present. Columellar callus and parietal callus thickened. Columella with 3-4 denticles. Siphonal canal short, open, slightly recurved. Teleoconch whorls off-white with irregular creamy brown marks, some stronger brown spots are present in a subsutural band. Protoconch whorls off-white. Aperture and columella white. Holotype height 5.9 mm.

Zafrona pleuriferoides n. sp. stands out from the other congeners by its protoconch with axial ribs, while most other congeners have a smooth protoconch. Z. pleuriferoides is also more bulbous, has more spiral cords and has spiral ribs inside the aperture, this last feature has not yet been seen in any other Zafrona.
