Description Small shells with an equatorial diameter around half a millimeter. The dorsal part of the shell is convex and evolute, bears heavily limbate whorl sutures and slightly limbate or smooth chamber sutures. The latter are curved and bent backwards. The periphery is keeled in accordance with the limbate nature of the whorl suture. The equatorial to axial diameter ratio varies from about 1.5 to 1.75. There are 6 chambers in early, nepionic stages and 8–10 chambers in the last whorl. The only proloculus that is measurable has a diameter of 0.04 mm. The ventral side of the shell is flattened and presents a relatively narrow umbilicus, covered but not closed by long folia. Their thickened adaxial tips fuse to form an annular rim around the axis. There is no umbilical pile in the coiling axis of the shell. [details]
