Shell fusiform, rather elongate, base not constricted. Protoconch prominent, rather wide, with rounded apex, consisting in 3.5 convex whorls, appearing smooth to the naked eye, finely granulose under optical microscope, and mamillated with rounded close-set tubercles under SEM; lower limit oblique and clear-cut, marked by change of colour, while on last whorl 2 cords progressively develop, beginning the sculpture of teleoconch. Teleoconch of 5 slightly convex whorls, with 3 spiral cords per whorl, crossed by finer axial ribs, with a rounded bead at each intersection; beads numbering 20 to 22 on penultimate whorl; beads of the upper cord a little weaker than others and constricted, including last whorl. Beads always small, widely spaced, the reticulated sculpture being more obvious than for other species. A fourth spiral cord emerging from suture at base of last whorl, smooth, and underlining angle with base. A further smooth cord at mid-height on base. Aperture circular. Colour pale brown, protoconch paler or whitish. Size: holotype total height 2.2 mm; width at base 0.8 mm; height of protoconch 0.60 mm; width of protoconch at base 0.29 mm.

Found dead in hand-dredged sand at 10-20 m, off Saint-Gilles-les-Bains. Remarks. This species differs from Cerithiopsis boucheti in its smaller size (2.2 mm instead of 4.5 mm), and its wider protoconch (3.5 whorls instead of 3). It differs from Cerithiopsis pickeringae in its smaller size (2.2 mm instead of 3.9 mm) and wider protoconch. From Cerithiopis nutzeii it differs in its higher protoconch (3.5 whorls instead of 2.5); and from Joculator species of the same colour, it differs in not having a constricted base.

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