Dilian Georgiev found topotypes of Viviparus sphaeridius Bourguignat, 1880, which has not been mentioned in the West European literature since its original description, except one citation by Westerlund (1886: 7). The rediscovery of this species is provided. As a result, V. sphaeridius is considered to represent a species in its own rights well distinguishable from the other European species in the genus Viviparus. Additionally, a key to the Viviparus species from Europe is given to facilitate future identification and prevent further misidentifications
