Original Description
"Test trochospiral with spiral side almost flat or very gently convex, the initial portion slightly elevated. Umbilical side strongly convex. 4.5 to 6 chambers in the last whorl gradually increasing in size, on spiral side petaloid to elongate separated by distinct arcuate and flush sutures, generally indistinct in the inner whorl; on the umbilical side, chambers triangular rapidly increasing in height, separated by radial depressed sutures. Equatorial periphery with distinct keel, slightly elongate to circular, gently lobate. Umbilicus narrow and deep. Aperture a low arch, umbilical-extraumbilical with a distinct imperforate lip. Wall calcareous, perforate, with a number of pustules sparsely distributed, covering particularly the central portion of the spiral side, and the periphery of the last 2 chambers. Pustules, completely covering the early chambers of the last whorl of the umbilical side, decrease in number and size towards the last, which is almost smooth. In the antepenultimate and penultimate chambers, pustules are concentrated in the umbilical area. Coiling 98% sinistral. Largest diameter of holotype 0.21 mm.
