Expansion of the ranges of land mollusks of the genus Xeropicta (Gastropoda, Hygromiidae) in Ukraine

Abstract

We analyzed samples of land mollusks of the genus Xeropicta collected on the Northern Black Sea Coast and others regions of Ukraine between 1990 and 2015. The findings indicate that the range of X. derbentina and X. krynickii has expanded as a result of human activities. Now the distribution of X. krynickii on the Northern Black Sea Coast is mainly limited to coastal territories. X. derbentina spreads much deeper into the mainland. Isolated colonies of this species were even recorded in the forest-steppe zone of Ukraine and in Zakarpattia oblast.
