Popis

The single white shell does not seem to belong to any described species, unfortunately it lacks the top; only a small part of the brown protoconch is visible, the whorl has a single keel and axial riblets. The following 8 whorls have on the upper whorls two rows of tubercles and between them a third appears; the tubercles are rounded, raised, located vertically one above the other. The last whorl has on the underside two conspicuous spiral cords and an obsolete one. Siphonal canal short and wide. The shell has a more or less conical shape, the whorls are considerably wider than high, the last whorl is barely larger in size than the previous one. Height about 3.5 mm, diameter 1 mm.

Diagnosis
Holotype height 3.2 mm. Shell conical with flat sides. Teleoconch of seven whorls, which have three tubercled spiral cords. The first two are well visible since the first teleoconch whorl, while a third appears later between the two main cords: it is initially a fine thread on the third whorl, and is fully developed on fifth whorl. The last whorl has a fourth weakly tubercled spiral cord, and the base has two further smooth cords. Only the last whorl of the protoconch is present in the holotype, but it is clearly multispiral and bears a single spiral keel and several axial riblets. Colour white, the visible protoconch whorl is light brown.
