Radix (Radix) auricularia (Linnaeus, 1758)

Distribution. We recorded the species in 4 localities: 2, 10, 17 and 33 ( fig. 1 , table 1 ); shell image is given in Anistratenko et al. (2018: fig. 3 , I). It was reported in the region earlier by other authors ( Zdun, 1960; Stadnichenko, Gyrin, 2011 a). In Ukraine this snail is known from all regions (Anistratenko, Сhernogorenko, 1989; Stadnichenko, 2004). General distribution — Palaearctic, introduced into North America ( Vinarski, Kantor, 2016).

Remarks. In the Transcarpathia R. auricularia inhabits shoreline zone of lowland (from 110 up to 170 m a. s. l.) rivers, reservoirs in their floodplain area and ponds associating mostly with macrophytes at depths up to 0.5 m (table 2).
