Radix (Radix) ampla (Hartmann, 1821)

Distribution. The species was recently listed and illustrated as new species for the regional malacofauna ( Anistratenko et al., 2018: fig.3 , O). Currently populations of R. ampla are registered in the Transcarpathia in 5 localities: 2, 18, 21, 43 and 45 ( fig. 1 , table 1 ). In Ukraine the species sometimes was mentioned under the name L. monnardi (Hartmann, 1844) from the Forest-Steppe and Polissya zones (Anistratenko, Сhernogorenko, 1989; Stadnichenko, 2004). General distribution — Europe and Siberia ( Vinarski, Kantor, 2016).

Remarks. In the Transcarpathia this species is found only in lowland (from 110 up to 200 m a. s. l.) rivers among vegetation at depths up to 0.5 m (table 2). Though some authors do not accept the validity of name R. ampla , a combination of features of shell morphology, proportions of the copulatory apparatus and molecular taxonomy confirm it is a distinct species (more details in Anistratenko et al., 2018).
