The European representatives of the genus Herpetocypris are revised, based on extant type material and various new collections. The revision is based on the hypothesis that species with syngamic populations will show large intra-specific morphological variability and small morphological differences between taxa. Of the nearly 20 extant nominal species, subspecies and varieties, 6 recent species are retained. Herpetocypris reptans, with both the common nominal subspecies and H. reptans curvata (known from its type locality only), occurs in most of Europe, north of the Mediterranean. Herpetocypris brevicaudata is the only species in which syngamic populations occur, these are thus far only found in the western part of the Mediterranean. Parthenogenetic populations occur throughout Europe. This species shows larger morphological variability. Herpetocypris mateusorum is confined to western Iberia. Herpetocypris chevreuxi-intermedia-helenae form a closely related species cluster, which occurs throughout Europe, at least H. helenae appears to have a global distribution. Some morphological peculiarities of this genus are discussed, as is the variability in several of the so-called diagnostic characters. Some remarks on the evolution in this genus are offered.
