Elsewhere in Europe it occurs only in the Balkan Peninsula in a few isolated populations at similar altitudes in the Dianaric Alps and in Macedonia. Further east it occurs in Turkey, being widespread in the mountains in the east of Turkey. It is also widespread in the Caucasus Mountains. There are also isolated populations on the border of NE Ukraine and Russia at much lower altitudes (around 300m) of the subspecies ergane.
