New habitats of Lymnaea (Stagnicola) saridalensis Mozley, 1934 were discovered in the former riverbed reservoirs of the basins of the Khopor and Sura rivers in the Volga Upland (Penza region). The parameters of the shell and the indices of the copulative apparatus (ICA), which is used for distinguishing species, were determined. Studied populations were characterized by a significant variability of ICA (0.183 ± 0.01 and 0.276 ± 0.012).
