Teleoconch pupiform, with pointed apex, topped by the prominent protoconch, general outline recalling that of a gothic tower; apical angle of teleoconch 55°; maximum width at the penultimate whorl; base slightly constricted. Protoconch high, nearly cylindrical, consisting in 4.5 convex whorls; its earliest 1.5 whorls smooth, the subsequent whorls with their upper 1/3 concave, smooth and finely frosted, their lower 2/3 convex and bearing slightly prosocline axial ribs (ribbed protoconch of type 4). Teleoconch of 6 whorls, rather low, suture moderately impressed; 2 spiral cords per whorl, crossed at right angles by axial ribs weaker than cords, reaching upper and lower suture, but discontinuous from one whorl to another; a rounded bead at each intersection, beads rather small and widely-spaced, numbering 20-21 per whorl. On last whorls, beads of upper cord progressively axially elongate, incised m on last whorl and divided near aperture by a spiral furrow. A fourth spiral cord emerging from suture at base of constricted last whorl, finer and bearing finer beads. Beads of the 4 cords becoming smaller towards outer edge of aperture, axial ribs becoming predominant. A fifth fine, smooth, unbeaded cord on base. Aperture roundly quadrate. Colour blackish-brown, protoconch and the first 2 whorls of teleoconch clearly paler or creamy-white. Size: holotype total height 2.7 mm; maximum width 1,2 mm; height of protoconch 0.42 mm; maximum diameter of protoconch 0.33 mm.

This species differs from Dizoniopsis herosae n.sp. in its more swollen shape, and its protoconch, the protoconch of D. herosae n.sp. being shorter with axial ribs extending from suture to suture. D. herberti n.sp. which has a similar protoconch of type 4, is easily separated by its colour pattern.

Réunion. Found dead in hand-dredged sand at 10-20 m, off Saint-Gilles-les-Bains.
