Genus Ellipsopyxella Bonnet, 1975

Diagnosis: Test resembles Geopyxella but with biaxial symmetry. In contrast to Ellipsopyxis the aperture is circular, not or only very weakly invaginated. During resting phases the pseudostome is closed by a mucous diaphragm. The test is composed of relatively flat mineral particles (crystalline quartz) giving a smooth surface, ventral sole thicker than the rest of the shell; pseudostome without organic lip.

Monospecific.
