- Physa acuta (Draparnaud, 1805) (fig. 4, 3–5) Distribution. This species was described from France and occurs in many European countries. However, some data evidence Ph. acuta is a species of Nearctic origin that apparently invaded other continents in Europe, Asia, Africa, Australia, and South America. Therefore it is considered as one of the most successful invaders among freshwater snails (for more details see Vinarski, Kantor, 2016; Vinarski, 2017). In Ukraine the species is widespread through almost the entire country being registered sometimes as Costatella integra (Haldeman, 1841) (Stadnichenko, 1990), Ph. taslei Bourguignat, 1860 (Anistratenko, Chernogorenko, 1989) or Physa skinneri Taylor, 1954 (Degtyarenko, Anistratenko, 2011). In the Transcarpathian Region Ph. acuta has been recorded several times (Stadnichenko, 1990; Anistratenko et al., 2018). Currently we found populations of this snail in few additional localities: 6, 9, 15, 18, 25 and 42 (fig. 1, table 1). It could not be excluded that findings of “ Physa fontinalis (Linnaeus, 1758) ” reported by Zdun (1960) from the Transcarpathia in reality are belonging to Ph. acuta. Remarks. The shell shape of Ph. acuta from Transcarpathia is highly variable, ranging from broadly to elongately conical (fig. 4, 3–5). However, at least some specimens (e. g. fig. 4, 3) match well the holotype of this species illustrated by Vinarski (2017). Some European authors use the genus name Physa for this species (Falkner et al., 2001; Glöer, 2002) while Physella is also in use (e. g. Vinarski, 2017). In the Transcarpathia this species inhabits shallow zone of both current and stagnant waterbodies. Snails usually occur in macrophytes associations at depths of 0.05–0.5 m, preferring warm area of the reservoir within the altitude range between 100 and 240 m a. s. l. (table 1, 2).
