Description
The heigth of the shell attains 0.85 mm, its diameter 1.05 mm.

The subsutural region is crenulated by short, broad riblets, with intervals between riblets bearing close-set, microscopic spiral threads. The riblets are much weaker towards the periphery. The microsculpture consists of numerous close-set microscopic axial threads. The riblets reappear on the base, crenulating the umbilical margin. The aperture is circular. The peristome is complete, circular, and slightly disjunct. The outer lip is simple. The interior lacks nacreous coating. The umbilicus is of moderate width.
