Synonyms
editMost authors misidentified Anisus calculiformis, applying the name Anisus septemgyratus to animals which are in reality Anisus calculiformis. So Anisus septemgyratus auct. (not Rossmässler) is synonymous with Anisus calculiformis.
The database WoRMS on the other hand considers this name a junior synonym of Anisus septemgyratus (Rossmässler, 1835) [2]
