In Ukraine the species is registered in all regions including the Transcarpathian ( Stadnichenko 2004 : Stadnichenko & Gyrin 2011 ). General distribution covers Western and Central Europe. Remarks: In the Transcarpathian this species occurs sporadically, inhabits mainly natural and artificial ponds, associated with macrophytes at depths of 0.5–1.0 m. Though genetic studies (e.g. Mezhzherin et al . 2008 ; Vinarski et al . 2012a ) did not reveal any reliable genetic traits distinguishing „ stagnalis ‟ and „ fragilis’ we treat these forms as two conchologically separated “morphospecies”. The proper status of L. fragilis is to be clarified by means of the integrative taxonomic approach.
