Shell rather large for genus, semi-translucent, adult size up to 9.5 mm (holotype); fusiform, bulbously elongate. Suture straight, with distinct subsutural rim. Protoconch multispiral, 3.5 whorls with fine axial ribs. Teleoconch of 4.5-4.75 whorls. Axial sculpture of very fine growth lines. Spiral sculpture of basal cords, ranging to adapical edge of columella; four to five weaker adapical basal cords ranging to mid-parietal height. Outer lip thickened, with distinct axial rim, bearing continuation of basal cords. Inner lip thickened, denticulate, with 10-12 equally spaced denticles, diminishing in strength abapically. Columellar callus slightly thickened, not demarcated. Parietal callus absent or very weak. Columella smooth. Siphonal canal short, open, straight. Teleoconch whorls beige in colour. Protoconch somewhat darker beige. Aperture and columella off-white to pale beige.

Pleurifera fulgens n. sp. is set apart from all congeners by the distinct subsutural rim in combination with the lack of both spiral and axial sculpture. Additional differences include the adapical cords ranging to mid-parietal height, the absence of the columellar rim and the thinner, semi-translucent shell.
