Bithinella [sic] (misspelling) Bythinella is a genus of very small freshwater snails, an aquatic gastropod mollusk in the family Bythinellidae (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

[1] Amnicola is a close relative, containing North American snails with essentially similar appearance and ecology.

The scientific name means "small Bithynia"; the latter snail genus is somewhat similar at a casual glance (though much larger) but not at all closely related among the Rissooidea.

The present genus occurs in springs, and sometimes caves or groundwater, from Catalonia across central Europe to the Aegean Region of Turkey.

Due to the limited range and special and easily destroyed habitat, these snails are liable to become endangered species.
