Shell high, fusiform, topped by the wide and cylindrical protoconch. Protoconch of 2.5 convex whorls, with a large rounded apex, appearing smooth but finely punctate under microscope, and under SEM, mamillated with small hemispherical close-set tubercles; limit from teleoconch along an oblique line marked by change of colour, but adult sculpture begins 1/4 whorl earlier by the progressive development of 2 beaded spiral carinas, continuing the 2 lower cords of teleoconch. Teleoconch of 6 whorls, 3 beaded spiral cords per whorl, subequal on last whorl, but upper cord weaker and retracted on earlier whorls. Weaker axial ribs crossing the cords at right angles, with a rather small bead at each intersection; beads numbering 24 on last whorl. Intervals occupied by very fine axial striae visible only under microscope. A fourth spiral cord emerging from suture at base of last whorl, as strong as other ones, but unbeaded. Base smooth. Aperture rounded. Colour plain orange-brown, protoconch white.
Size : holotype total height 3.4 mm, maximum width 1 mm; height of protoconch 0.46 mm; width of protoconch at base 0.29 mm.

This species differs from other allied Cerithiopsis of Reunion, in its smaller size and its 2.5 whorled protoconch. It differs from Joculator species of the same colour, in its larger size and unconstricted base.
