This is one of the widespread pond snails in Forest-Steppe and Polissia zones of Ukraine ( Stadnichenko, 2004 ) as well as in the Transcarpathian region ( Stadnichenko, Gyrin, 2011 a ; Anistratenko et al., 2018 ). General distribution — Palearctic ( Vinarski, Kantor, 2016 ). Remarks. Shell of specimen from the Transcarpathia is illustrated by Anistratenko et al. (2018 : fig. 3 , N). In the Transcarpathia this species is the common snail inhabiting shallow zone of rivers and canals up to 500 m a. s. l. mostly associating with macrophytes; it also occurs in small natural or even artificial ponds: localities 3, 6, 12, 15, 16, 19, 27, 30, 44 and 46 ( fig. 1 ). Environmental conditions for the recorded populations of R. intermedia are presented in tables 1 and 2. This species shows close resemblance to R. balthica and can be distinguished from the latter by its higher spire and more oblong shell. The validity of name R. intermedia is accepted in Russian literature (e. g. Kruglov, 2005 ), while the Western European malacologists usually consider it as a synonym of R. balthica .
