 (2010) proposed that species of clade C2 (including "Stagnicola fuscus") should all be called "Lymnaea", according to the principle of priority of the International Code of Zoological Nomenclature (ICZN).Then this species would be named Lymnaea fusca Pfeiffer, 1821.The "Lymnaea palustris" aggregate species is recorded from western Europe to beyond the Arctic Circle and across Siberia.
