Characterization (by Bas Kokshoorn): Shell moderately fragile, broadly conical in appearance, white, reaching at least 7.8 mm in length. Length/width more than 2.0. Protoconch absent. Teleoconch whorls at least 6 1/2, separated by a very deep, fenestrate suture. Teleoconch with evenly spaced, thin, blade-like costae, heavily damaged in this specimen. Costae are orthocline. Outer margin of costae bend abaperturally over whole of their length. Costae are not coronate and are fused with those on adjoining whorls. The interspaces between the costae are smooth. Number of costae 7, this appears to be constant over the whorls. Aperture absent. Umbilicus absent.
