Lymnaea stagnalis (Linnaeus, 1758)

Distribution. In Ukraine L. stagnalis is registered in all regions (Anistratenko, Сhernogorenko, 1989; Stadnichenko, 2004) being recorded also in Transcarpathia (Zdun, 1960; Stadnichenko, Gyrin, 2011 a; Anistratenko et al., 2017). The species is one of the most common and widespread pond snails in the region — we found its populations in 9 localities: 1, 6, 12, 14, 15, 22–24 and 32 (fig. 1, table 1).

Remarks. The image of snail from the Transcarpathia is provided by Anistratenko et al. (2018: fig. 3, A). In the Transcarpathian Region this species inhabits both hard and soft substrates in shallow zone of rivers, former riverbeds, lakes, natural and artificial ponds. We recorded L. stagnalis in the altitude range between 100 and 170 m a. s. l. where it is associated mostly with macrophytes at depths of 0.5–1.0 m (table 2).
