Ostracoda - Podocopida - Trachyleberididae
Alexander (1933) originally misidentified the type species as Cythere sphenoides(/i). In this publication (Puckett, 2002), the correct identification of Alexander's type material from the Brownstown Formation (early Campanian) of northeast Texas is recognized as Brachycythere crenulata Crane 1965.
