In 1951, the Swedish malacologist Bengt Hubendick published a catalog of species-group names in the family Lymnaeidae proposed since 1758. This catalog includes 1151 entries, with information on their type localities, bibliographic references, and the position of each taxon in the then used system. Extinct taxa were not listed. This publication is an expanded and substantially revised version of Hubendick's catalog, taking into account all species-group names proposed for the pond snails, from 1951 to 2024, as well a number of names once overlooked by Hubendick. The present Nomenclator contains 1557 names, for each of which a reference to the original description, an indication of the type locality, the position of the taxon in the current system, and an indication of a later publication in which a photographic image of the type is given (if such a publication occured). In some cases, taxonomic and nomenclatural remarks are provided regarding the status of particular taxa.
