Genus Viviparus Montfort, 1810

Type species: Helix vivipara Linnaeus, 1758

The area of distribution of Viviparus in Europe covers almost all its territory, the eastern and southern parts of the Black Sea coast and Western Transcaucasia. River snails are only absent in the waters of the southwestern sector of the Iberian Peninsula, as well as in a part of the far north and south of Europe. No other notable gaps in the distribution of the genus have been found, and therefore, the European range of Viviparus can be considered completely delineated ( Anistratenko et al., 2014).
