Author & date of last revision: admin on 20 November 2011
Anatomical evidence is presented to confirm that the taxon formerly regarded as Lymnaea palustris (Muller, 1774) includes a second British species, L. (Stagnicola) fuscus (C. Pfeiffer, 1821). The two species are assigned to the genus Stagnicola, (Jeffreys, 1830), as currently accepted by modern continental authorities.
