The distribution of this species is Eastern Alpine and Western Carpathian.
The type locality is the High Alps in Styria, Austria.

The key area of its range is in the Western Alps (from the south-western part of the Alps to Croatia, and also to the Dolomites in the southern Tyrol).

Austria
Germany
Czech Republic – 7 confirmed sites in Ore Mountains in Bohemia, locally extinct in Moravia.
Already Vojen Ložek has been calling for the effective conservation of this species in the 1980s.
It is one of the most endangered species in the Czech Republic, restricted to hidden and undisturbed natural deciduous forests.
Originally it was known from 16 sites in the Ore Mountains (Krušné Hory Mts.),
in the northwestern Bohemia, Czech Republic and one site on the slope of Smrk Mount in the Moravian-Silesian Beskids (Moravskoslezské Beskydy Mts.),
East Moravia, Czech Republic.

extinct in Moravia: The forest at the only (but well populated) locality in the Moravia has been seriously damaged by air pollution from factories (such as Třinec Iron and Steel Works and others) jointly with the 20 °C dropping of temperatures in inversion on 31 December 1978.
The nearly all pollution-damaged stand died out at the southwestern slope on the Smrk Mount.

in Bohemia: The occurrence of the snail was recently confirmed only at seven sites in the Krušné Hory Mts.
Remaining sites were destroyed due to human impacts, mainly acid rains and insensitive forest management mainly due to removal of dead wood and clearcutting.
Therefore, its populations survived only in forest patches hidden in hardly accessible places.

Slovakia – in the eastern part of Low Tatras, in the peak level of Poľana, Klenovský Vepor Mount in the Vepor Mountains, Muránska planina and the Ondrejsko in Slovak Paradise is the easternmost.
All of these records in the Slovakia are coming from 1960s-1970s and there has been no verification since.
