Segmentina nitida (O. F. Müller, 1774) ( fig. 4 , 15–17)

D i s t r i b u t i o n. Global range of this species covers Europe and the Western Siberia ( Vinarski, Kantor, 2016). In Ukraine S. nitida is known from the Polissya, Forest-Steppe, Steppe zones and Crimea (Anistratenko, Chernogorenko, 1989; Stadnichenko, 1990). It was recently registered in the Transcarpathian Region ( Anistratenko et al., 2018). Additionally in the malacological collection of State Museum of Natural History in Lviv are found two lots labeled as S. nitida which sampled in Transcarpathia in 2004 ( Furyk, 2018). Since the records of S. nitida are limited in Ukrainian Transcarpathia by a very few locations, we assume that it is a regionally rare species; at least we found S. nitida in only one locality (14).

Remarks. We found the population of S. nitida in a roadside canal ( table 1 ) with warm water (T = 25.7 °С) located in lowland area, (110 m a. s. l.); density of this community was about 20–30 individuals per m 2. Molluscs were crawling among the stalks and leaves of Iris pseudacorus L.
