Original description:

The shell (about 130–140 μm long) has an asymmet- ric, elliptic shape. In the centre of the shell often a spongy, dark disc can be found, which is surrounded by about three whorls of a single (?) spiral, which are generally irregular in shape. In some specimens the spiral is very weak or absent. A distinct polar cap can be seen in many specimens. The shell surface is rather smooth, due to the irregular-sized pores which lack frames. A wide pylome with teeth is present.
