Planorbis planorbis (Linnaeus, 1758) ( fig. 3 , 9–11)

Distribution. According to our data, the species is one of the rarely recorded pulmonate snails in the region — we found its populations in only two localities: 13 and 15 ( table 1 ). In Ukraine P. planorbis is registered in all regions (Anistratenko, Сhernogorenko, 1989; Stadnichenko, 1990) including the Transcarpathia ( Zdun, 1960; Stadnichenko, Gyrin, 2011 b; Anistratenko et al., 2018). Global distribution — Europe, Northern Africa, and Siberia ( Vinarski, Kantor, 2016).

Remarks. In the studied region P. planorbis inhabits stagnant (even temporary or semi-permanent) and running waters usually occurring in- and under stones or macrophytes. We recorded P. planorbis only in lowland part of the region at a depth of 0.3–0.5 m ( table 1 , 2).
