Lymnaea fragilis (Linnaeus, 1758) Distribution. In Ukraine L. fragilis is registered in all regions including the Transcarpathian (Anistratenko, Сhernogorenko, 1989; Stadnichenko, 2004; Stadnichenko, Gyrin, 2011 a). The species is recorded in five localities of the Transcarpathian Region: 10, 13, 17, 23 and 24 (fig. 1, table 1); the shell is illustrated by Anistratenko et al. (2018: fig. 3, B). Remarks. In the Transcarpathian this species occurs sporadically, inhabiting mainly natural and artificial ponds and associating with macrophytes at depths of 0.5–1.0 m. We recorded L. fragilis in the same altitude range as previous species (table 2). Although the taxonomic status of “ fragilis ” is not commonly accepted (Vinarski, Kantor, 2016), we treat this form as a conchologically distinct “morphospecies ” (Anistratenko et al., 2018).
