Brief description.

Shell dextral, with about 6 whorls. Penultimate whorl slightly expanded; body whorl nearly as wide. Constriction at the middle of the parietal wall. Teleoconch with weak, widely-spaced, radial ribs; ca. 7–9 ribs per 0.5 mm on penultimate whorl. Dorsal fold absent. Umbilicus unknown. Double lip present. Columellar tooth present. One horizontal palatalis just above the columella. One vertical palatalis.
