Original description: [Davey, 1969, p. 141]:

Diagnosis:
Shell subspherical; shell wall thick and densely granular.
Angular apical archaeopyle typically present.

Description:
The shell wall is thick (2-3 µm) and may be composed of two layers. If the wall is bipartite then the inner layer is thin, the outer layer making up almost the entire wall thickness. This layer appears to be composed of minute cellular elements and is densely granular on the surface.
The apical archaeopyle, when developed, is angular with small slits passing posteriorly from its margin between each precingular plate.
A sulcal notch is also present.
Plate boundaries and cingulum are not discernible.
