This name is proposed for a genus of the Mangiliinae, in which the aperture has not acquired armature, and in which the lip is not flexed. Prominent radial ribs are over-ridden by fine beaded spiral threads. The apex is mucronate (i.e. with a small pointed projection, or spine-like ending), with smooth whorls. Characteristic is a colour scheme of a peripheral zone of brown or black or orange, sometimes broken into a series of dots or clashes.[2]
