Range DescriptionThis is one of the most widespread species for Central Europe, where it lives in Great Britain, Norway, Sweden, Denmark, Baltic countries, Poland, Ukraine, Northern Moldavia, Germany, Benelux countries, central France, Switzerland, Austria, Slovenia, Cech Republic, northern Croatia, Serbia, and northern Italy (Sysoev and Schileyko 2009; Kerney et al. 1983; Gittenberger 2004).
Special attention should be paid to the Irish distribution, as the species is almost confined to the northern half of Ireland with two outlying sites in Cork where it may have a recent origin. Its range in the north of Ireland suggests that it may have originated from neighbouring areas of Scotland relatively late in the Postglacial period. A similar distribution and therefore origin is posited for Arion owenii and the carabid beetle Carabus nitens (Byrne et al. 2009).
