Shell very small and pupiform, its slender apex topped by protoconch, and constricted at base. Protoconch of 5.5 convex smooth whorls, the last one wide and ventricose, its limit from teleoconch marked by beginning of sculpture along an oblique line; the earlier whorls regularly tapering to the rounded but very narrow apex. Teleoconch of 4.5 whorls, with 3 subequal spiral cords per whorl, crossed at right angles by weak axial ribs, with a rounded bead at each intersection; beads close-set, numbering 23-24 per whorl. A fourth beaded spiral cord emerging from suture at base of last whorl, weaker than the other ones. 2 weak and unbeaded spiral cords on base. Aperture rounded. Colour plain orange-brown, vivid when fresh, the 3 last whorls of protoconch brown, the earlier 2 white. Size: holotype total height 1.9 mm, maximum width 0.6 mm; height of protoconch 0.42 mm; width of protoconch at base 0.30 mm.

This species resembles Joculator minima Laseron in its shape, but differs from it in its smaller size (1.9 mm instead of 2.3 mm) and its 3 rows of equal beads. It differs from Bittium (Joculator) uveanum Melvill & Standen, 1896, from Loyalty Isl. in its smaller size (1.9 mm instead of 2.3 mm), its less swollen shape, its finer and more numerous beads, and its colour; it differs from Joculator myia in its protoconch (brown tinted and more acute) and in its more orange colour.

Réunion: Found dead in hand-dredged sand at 30m, off Boucan-Canot beach, Saint-Gilles-les-Bains.
