Original description: Test generally in the 100–150 μm range, with three whorls in a trochoid coil. The relatively small initial whorls stand in contrast to the large, final whorl with four chambers, regularly increasing in size. Our specimen photographs show the relatively flat spiral base of the last whorl. The axis of coiling tilts in the large penultimate chamber, resulting in progressive forward tilting over the umbilicus and culminating in crescentic shape of the other three chambers in the final whorl. Sutures depressed, aperture umbilical, a low and elongate arch to high arched, with a rim. Umbilicus closed. Wall microperforate, with many small pustules and scattered pore mounds.
