Lithoglyphus naticoides (C. Pfeiffer, 1828) ( fig. 3 , 8)

D i s t r i b u t i o n. Native range of L. naticoides covers the Central and Eastern Europe. In the Ukraine the species inhabits all regions including the Transcarpathia ( Anistratenko, Stadnichenko, 1995; Stadnichenko, Gyrin, 2011 b; Anistratenko et al., 2017). Recently we found populations of this snail in 5 localities: 6, 9, 10, 12 and 45 ( fig. 1 , table 1 ).

R e m a r k s. Some authors (e. g. Falkner et al., 2001; Welter-Schultes, 2012) recognize within the genus Lithoglyphus a single species, L. naticoides , while others consider 2–3 ( Alexenko et al., 1990; Anistratenko, Stadnichenko, 1995; Glöer, 2002) or even more distinct species ( Bank, 2014). It can not be excluded that some findings of L. fuscus from the middle sector of the Danube basin (e. g. Cioboiu, 2013) actually concerned to L. naticoides . In the Transcarpathia L. naticoides inhabits small and large rivers; preferable biotops for the species are the silty or clayish substrates, molluscs are often associated with macrophytes in shallow zone of rivers at depths of 0.15–1.3 m. In the Middle Danube this species occupies mostly biotopes with sandy-clayish bottom sediments ( Cioboiu, 2013).In the Latorytsa River (localities6, 9 and 10) these molluscs coexist with Bithynia tentaculata and numerous pulmonate species ( table 1 ).
