The species is recently found at a single locality and was declared as formally new species for the Transcarpathian malacofauna ( Anistratenko et al., 2018 : shell illustrated in fig. 3 , J, K). At the same time some records of R. peregra (O. F. Müller, 1774) in there as well as in adjacent Ivano-Frankivsk Region ( Stadnichenko, 2004 ) might be treated as R. parapsilia . Currently only three localities of this species are discovered in the region: 16, 53 and 56 ( fig. 1 , table 1 ). Distribution of R. parapsilia in Ukraine is also not clearly studied and needs more extensive field samplings. General distribution — Northern Eurasia ( Vinarski, Kantor, 2016 ). R e m a r k s. In the Transcarpathia the species is found in shallow zone of rivers, streams and canals from 120 up to 540 m a. s. l. (table 2). Long time this species had been known in the Russian literature as Lymnaea ( Radix ) psilia (Bourguignat, 1862) . However, Vinarski and Glöer (2009) showed that the syntypes of L. psilia represent juvenile specimens of L. stagnalis and thus a substitute name was created to replace L. psilia sensu Kruglov, 2005 non Bourguignat, 1862. The specimens of R. parapsilia differ from the typical R. auricularia by its higher spire and less inflated body whorl ( Anistratenko et al., 2018 : compare fig. 3 , I and fig. 3 , J, K).
