Diagnostic Features	Test weakly cordate in outline. Apical disc ethmolytic; 4 gonopores. Anterior ambulacrum slightly depressed; pore-pairs small. Paired ambulacra V-shaped; anterior paired petals with upper half of anterior column bearing only rudimentary pore-pairs. Labral plate long and narrow, extending to 4th or 5th ambulacral plate; sternal plates fully tuberculate. Peristome slightly oblique but without projecting labral lip. Peripetalous fasciole present, bisecting the petals; subanal fasciole also present.
Distribution	Middle Eocene (Lutetian), Egypt.
Name gender	feminine
Type	Bahariya teetotumensis Elbassyony, 2005, p. 324, by original designation.
Species Included	Only the type species.
Classification and/or Status	Irregularia, Spatangoida, Loveniidae Subjective junior synonym of Gualtieria Agassiz, 1847
Remarks	Elbassyony (2005) recognized this to be close to Gualtieria, differentiating it on the basis that the lower portion of the anterior petals below the peripetalous fasciole is V-shaped, not parallel. However, this feature is variable and a similar morphology can be found in specimens of Gaultieria (e.g. see G. grossouvrei Lambert, 1912) . Elbassyony, A. A. 2005.
