Granaria F. Held, 1837

Type species (design. Herrmannsen, 1847: 488): Pupa frumentum Draparnaud, 1801 .

Notes.—The genus Granaria is disjunctly represented by 7 extant species, in a very large area, reaching from western Europe in the west towards Iran in the east. Two species groups can be distinguished on the basis of distributional data, i.e. a western group, represented from the Iberian peninsula to the Balkans and a poorly known eastern group, known after few samples from Iran, Pakistan, Oman and Yemen. The phylogenetic relationships of the latter group of conchologically similar species is uncertain. Maybe the eastern group of alleged Granaria species is more closely related to Granopupa . Because conchological, autapomorphic character states are unknown, their classification will remain problematic as long as both anatomical and molecular data are not available. The same problem, but seemingly insoluble in this case, applies to the generic classification of the pre-Pleistocene fossil taxa.
