Radix (Peregriana) lagotis (Schrank, 1803) (fig. 4, 2)

Distribution. According to our data, R. lagotis is widespread and quite common species of pond snails in the Transcarpathia. It was formally listed in the regional fauna long time ago (Zdun, 1960) though it still unclear whether or not a determination of snails was correct. Currently populations of the species are found in 6 localities: 7, 8, 27, 29, 48 and 55 (fig. 1, table 1). In Ukraine R. lagotis is registered in all regions (Anistratenko, Сhernogorenko, 1989; Stadnichenko, 2004). General distribution — Northern and Central Palearctic (Vinarski, Kantor, 2016).

Remarks. In the Transcarpathia R. lagotis occurs in the similar biotopes as R. peregra living in slowly running rivers, temporary or semi-permanent waterbodies in the altitude range from 110 up to 540 m a. s. l. (table 1, 2). In shell shape R. lagotis differs from R. peregra by its lower spire and more wide body whorl.
