Galba subangulata (Roffiaen, 1868)

( Fig. 3 , E)

Distribution: The species found at a single locality 16 ( Table 1); it has not been recorded from Transcarpathian region so far ( Stadnichenko & Gyrin 2011) though some reports of Galba ventricosa (Moquin-Tandon, 1855) might be referred to G. subangulata . In Ukraine the species is distributed in the Steppe and Forest-Steppe zones ( Stadnichenko, 2004). General distribution – Europe, southwest Siberia, and Central Asia.

Remarks: In the Transcarpathian the species inhabits hard substrates in shoreline zone of lowland rivers.

Taxonomic remarks: This (morpho)species is characterized by ovate-conical shell with a spire shorter than that of G. truncatula . The body whorl is visibly inflated.
