Bithynia tentaculata (Linnaeus, 1758) (fig. 3, 4) D i s t r i b u t i o n. Global range of B. tentaculata covers the Europe and Western Siberia. In Ukraine the species is the most common bithyniid species in all regions except the mountainous areas of Carpathians and Crimea (e. g. Anistratenko, Stadnichenko, 1995). In the Transcarpathia its populations are rarely occurred (Zdun, 1960; Anistratenko et al., 2017, 2018) in the lowland area. Altogether we only recorded this species in 3 localities: 8, 9 and 15 (fig. 1, table 1). Remarks. In the Transcarpathian region B. tentaculata inhabits shallow, slowly current and mostly warm (up to 25.6 °С) waters of rivers and their floodplains; it sometimes occurs in small artificial ponds (locality 8). Molluscs are usually associating with macrophytes at depths of 0.1–1.5 m at various bottom sediments (silty, sandy, stony, etc.).
