Petasina unidentata (Draparnaud, 1805) – a new species for the mollusc fauna of the Roztocze Upland (SE Poland)

Abstract

The hygromiid land snail Petasina unidentata (Draparnaud, 1805) was found in a new locality in south-eastern Poland. The site is located in the Czartowe Pole Nature Reserve, outside the continuous distribution range of the species and represents its easternmost occurrence. Given its ecological preferences for woodlands, it is unlikely that the species is a recent anthropogenic introduction. It may be rather considered as a postglacial or even interglacial immigrant and thus relict species.
