Anisus septemgyratus (Rossmässler, 1835) (fig. 4, 6–8)

Distribution. In the studied region the species found at a single locality (58 — table 1). In the rest part of Ukraine A. septemgyratus the populations are also not abundant although occur in all regions (Anistratenko, Сhernogorenko, 1989; Stadnichenko, 1990). Global distribution — Europe (Glöer, Meier-Brook, 2008; Vinarski, Kantor, 2016).

Remarks. In the Transcarpathian Region mollusc is recorded in various types of waterbodies (Stadnichenko, Gyrin, 2011 b); we found it only in streams in the highland zone (550 m a. s. l.) along with Terrestribythinella baidashnikovi, Galba truncatula and Ancylus fluviatilis (table 1, 2). The shell characteristics of A. septemgyratus from Transcarpathia match well the fully-grown specimen illustrated by Glöer and Meier- Brook (2008) who clearly argued distinctness of this species from others similar Anisus .
