Its European distribution includes the Iberian Peninsula (Spain, Portugal and the Balearic Islands), Southern France, Corsica, Peninsular Italy, Sicily and Sardinia up to North-eastern Greece (Jalas & Suominen, 1983). On the African side, the species can be found in Morocco, Algeria and Tunisia, while it does not occur in the Canary Islands (Marhold, 2011).
