Genus Kempioconcha Preston, 1931

The space between the axial ribs on the apical whorls, although generally being wider than on the lower whorls, varies significantly even within a single population. Subadults have a much more elongated aperture with a straight columellar margin and a noticeable columellar-basal angle. These “characters” caused some confusion in the earlier works on this genus (often been treated as a subgenus of Pseudoglessula ).
