Radix (Peregriana) peregra (O. F. Müller, 1774) ( fig. 4 , 1 )

Distribution. The species is common in the Transcarpathia (e. g. Zdun, 1960) and currently found in 7 localities: 16, 29, 30, 40, 53, 59 and 60 ( fig. 1 , table 1 ). According to Stadnichenko (2004) R. peregra is known in Ukraine from all regions. General distribution — Europe and southern part of the Western Siberia ( Vinarski, Kantor, 2016).

Remarks. Our observations suggest that in the Transcarpathia R. peregra inhabits rivers, temporary or semi-permanent waterbodies and wetlands, preferring the swampy biotopes in the altitude range from 480 up to 850 m a. s. l. ( table 1 , 2). Stadnichenko and Gyrin (2011 a) recorded these molluscs in shallow zone of Lake Synevir-Polyanske (984 m a. s. l.).
