Current taxonomic allocation.

Climo and Pullan (1972) considered it to be a synonym of Galba (Galba) truncatula (O.F. Müller, 1774) introduced to New Zealand after advent of Europeans, however Dell (1956: 74) noted some slight conchological differences between Limnaea alfredi and Galba truncatula and stated that Limnaea alfredi "has had a history in New Zealand that pre-dates European influence" and that "it is a truly indigenous form". Hubendick (1951) synonymized Limnaea alfredi with Limnaea tenella Hutton, 1885, but Dell (1956) was able to show that the latter species name was based on juvenile shells of the introduced from Europe Lymnaea stagnalis (L., 1758).
