D i s t r i b u t i o n. In Ukraine A. fluviatilis is registered in all regions except Crimea (Anistratenko, Сhernogorenko, 1989; Stadnichenko, 1990). This river limpet was repeatedly recorded in the Transcarpathian Region ( Zdun, 1960; Stadnichenko, Gyrin, 2011 b; Anistratenko et al., 2018) where it appears to be one of the most common and widespread pulmonate species — we found its populations in 7 localities: 12, 18, 19, 25, 28, 51 and 58 ( table 1 ). Global distribution — Europe, Northern Africa and north-western Asia ( Vinarski, Kantor, 2016).

Remarks. According to our observations in Transcarpathia, this species inhabits shallow (up to 0.2 m) zone of springs and rivers in both lowland and mountainous areas in the altitude range 110–570 m a. s. l. (table 2). Limpets prefer clean and oxygen-rich conditions with hard, mostly rocky substrates on the surface of which they are firmly adhere.
