Genus Terrestribythinella Sitnikova, Starobogatov & V. Anistratenko, 1992

Type species: Terrestribythinella baidashnikovi Sitnikova, Starobogatov & V. Anistratenko, 1992

The group is under the ongoing study aimed to re-assess the diversity, taxonomic rank and position of this group basing on combination of morphological and genetic approaches (Anistratenko et al., unpublished data). It is required since the shell morphology as well as bionomy of all three species currently attributing to Terrestribythinella show striking similarities with Bythinella . Untill this study is completed, we still considering terrestribythinellid as a distinct genus and family of Carpathian spring snails.
