Original description:

The shell is elongate egg-shaped and about 120 μm long. The interior of the shell is usually empty, although a delicate set of widely spaced elongated medullary shells can be seen in some specimens. A well-developed pylome with teeth is visible at one pole, which often forms a tube-like structure. The medium-sized pores are circular and rather regularly arranged. They are surrounded by weak frames. The surface varies from smooth to somewhat thorny due to variably developed pore frames. The outer shell wall is rather thin.
