Segmentina montgazoniana Bourguignat View in CoL in Servain, 1881 ( fig. 4 View Fig , 18–20)

D i s t r i b u t i o n. In the Transcarpathia S. montgazoniana is registered for the first time and is a formally new species for the regional fauna. Currently its populations are found in two localities: 6 and 7 ( fig. 1 View Fig , table 1 View Table 1 ). In Ukraine S. montgazoniana is known from the Polissya and Forest-Steppe zones (Anistratenko, Chernogorenko, 1989; Stadnichenko, 1990). Global distribution — Europe ( Vinarski, Kantor, 2016).

Remarks. In the Transcarpathia S. montgazoniana occur in shallow permanent waterbodies (rivers and their floodplains) on vegetation within the lowland area (ca. 100 m a. s. l.) ( table 1 View Table 1 , 2). European authors usually consider diversity of Segmentina as confined to one morphologically variable species, S. nitida ( Falkner et al., 2001; Glöer, 2002; Welter-Schultes, 2012). However, some anatomical and conchological differences allow distinguishing among this group several separate species ( Kruglov, Soldatenko, 1997) of which S. montgazoniana is recorded in the studied region.
