Remarks. This species has been listed either as a member of the genus Pseudoparella or of Epistominella among Japanese workers who focused on the character of the aperture parallel to the periphery. We follow Jones’s (1994) placement in the genus Alabaminoides . It is characterized by a noncarinate periphery, a small number of chambers and a slightly raised dorsal (biconvex) test, not like Epistominella .

Occurrence. Rare in the Yonahama Formation, sporadic in the Minebari Formation.
