The moderately large (about 160 μm), spherical to sub-spherical shell has a very rough surface, which is formed by massive frames. The small- to medium-sized, irregularly arranged pores are separated by large bars, the outer wall is rather thick. The double (?) spiral whorls of the inner shell are weak to absent and some specimens are filled only with spongy meshwork. Clusters of short polar spines can be found in some specimens. A pylome is not visible.

Biostratigraphic distribution
Geological Range: Last occurrence (top): within Neogene Period (2.59-23.03Ma, top in Piacenzian stage). Data source: Lazarus et al. 2015 - "N age group" First occurrence (base): within Neogene Period (2.59-23.03Ma, base in Aquitanian stage). Data source: Lazarus et al. 2015 - "N age group"
Plot of occurrence data:
Range-bar - range as quoted above, pink interval top occurs in, green interval base occurs in.
Triangles indicate an event for which a precise placement has been suggested
