Galba truncatula (O. F. Muller, 1774)

Distribution. In Ukraine the species is registered in all regions including the Transcarpathian (Zdun, 1960; Stadnichenko, 2004; Stadnichenko, Gyrin, 2011 a; Anistratenko et al., 2017, 2018: shell illustrated in fig. 3, D). According to our data, this is one of the most widespread and abundant lymnaeid species in the region — we found its populations in 12 localities (table 1).

R e m a r k s. In the Transcarpathia area this species inhabits cool to warm (T = 10.0–23.3 °С) waterbodies of various types: rivers, streams, lakes, ponds and marshes from 115 up to 730 m a. s. l., see table 2. Usually the populations of G. truncatula characterize by a high dencity — hundreds individuals per m 2. Sometimes snails are occurred in amphibiotic conditions due to their ability to still alive in temporarily dried waterbodies (Anistratenko et al., 2018).
