Radix (Radix) auricularia (Linnaeus, 1758)

( Fig. 3 , I)

Distribution: The species is found in 2 localities ( Table 1); one of them agrees with recently published record ( Stadnichenko 2004; Stadnichenko & Gyrin 2011). In Ukraine the species inhabits all regions ( Stadnichenko 2004). General distribution – Palaearctic, introduced into North America.

Remarks: In the Transcarpathian this species found in rivers, former riverbeds and ponds associating mostly with macrophytes at depths up to 0.5 m.

Taxonomic remarks: This species is very well studied. It has many times been characterized in the literature, both conchologically and anatomically ( Jackiewicz 1998; Glöer 2002; Kruglov 2005). Our samples of this species correspond with these descriptions.
