Anisus spirorbis (Linnaeus, 1758) ( fig. 4 , 9–11)

D i s t r i b u t i o n. Like the previous species, A. spirorbis represents a rarely recorded pulmonate snail in the studied region — we found its populations in two localities: 16 and 54 ( table 1 ). In Ukraine A. spirorbis occurs in all regions (Anistratenko, Сhernogorenko, 1989; Stadnichenko, 1990) including the Transcarpathia ( Stadnichenko, Gyrin, 2011 b; Anistratenko et al., 2018). Global distribution — Europe, Northern Africa, Middle Asia, Siberia ( Glöer, Meier-Brook, 2008; Vinarski, Kantor, 2016).

R e m a r k s. In the Transcarpathian Region snails live in small temporary ponds, canals and wetlands at a depth of 0.1–0.3 m; sometimes molluscs can be found in streams up to 620 m a. s. l. ( table 1 , 2). The specimens from Transcarpathia match well the images of A. spirorbis provided by Glöer and Meier-Brook (2008) .
