Radix (Peregriana) ampullacea (Rossmässler, 1835)

Distribution. The species is only found in three localities (2, 15 and 44, see fig. 1 , table 1 ) in the Transcarpathian Region. In Ukraine R. ampullacea inhabits all regions (Anistratenko, Сhernogorenko, 1989; Stadnichenko, 2004). General distribution — Europe and Siberia ( Vinarski, Kantor, 2016).

Remarks. The Transcarpathian populations of the species are characterized by low density; the snails occur here only in rivers or, rarely, in streams from 110 up to 200 m a. s. l. (table 2) at depths up to 0.5 m. Some malacologists (e. g. Glöer, 2002; Welter-Schultes, 2012) do not recognize R. ampullacea as a valid species name considering it as a synonym of R. balthica . However some others (e. g. Сhernogorenko, 1989; Stadnichenko, 2004) define this taxon as a distinct species having almost spheroid shell and very low spire; the body whorl is much more inflated in comparison to R. balthica — compare shell images given in Anistratenko et al. (2018). Its identity needs to be verified with using of molecular data.
