Planorbarius corneus (Linnaeus, 1758) ( fig. 3 , 12, 13)

Distribution. In the Transcarpathian Region P. corneus is apparently one of the common and widespread species — we found its populations in 8 localities: 6–8, 13, 15, 22, 23 and 32 ( fig. 1 , table 1 ). In Ukraine P. corneus is registered in all regions (Anistratenko, Сhernogorenko, 1989; Stadnichenko, 1990); it was listed also in Transcarpathian ( Zdun, 1960; Stadnichenko, Gyrin, 2011 a; Anistratenko et al., 2018). Global distribution — Europe and the Western Siberia ( Vinarski, Kantor, 2016).

Remarks. In the Transcarpathia this species usually inhabits shallow zone of permanent lotic and lentic waterbodies within the altitude range 100–170 m a. s. l. mostly associating with macrophytes; it also occurs in small natural and artificial ponds ( table 1 , 2). Apart the P. corneus, Stadnichenko and Gyrin (2011a) reported in the Transcarpathia fauna also P. purpura (O. F. Müller, 1774) and P. grandis (Dunker, 1850) . Conchologically both P. purpura and P. grandis can be differentiated from P. corneus ; however, Western European malacologists do not recognize the former taxa as distinct species and regard them as junior synonyms of P. corneus ( Glöer, 2002; Welter-Schultes, 2012).
