The main part of of this species' range occurs in Italy, but it crosses the border into France and Switzerland. It inhabits the southern part of the Alps, the Po lowlands, and the Appenine mountains south to Calabria (Brünner et al. 2002). Further research is required to determine the distribution limits of this species. The northern boundary of its distribution is poorly defined, and in southern parts of its range it is confined to higher altitudes and its distribution is patchy; in general it is more patchily and less extensively distributed than shown on the map.

It occurs from the Po plain to at least 1,300 m (Brünner et al. 2002).
