Diagnoza

Small shell, almost planispiral with a flat dorsal side and a wide, flat umbilicus without any particular demarcation from the base; coils of the teleoconch are rounded, connected only in a narrow area, covered with a sculpture of spirals and very dense, rib-like reinforced growth lines. Aperture round.

Porównanie

Differs from Frederikella mainly by the almost planispiral coiling and by the stronger collabral axial ribs.
