DistributionRead full entry
Range DescriptionThis species has a wide and highly fragmented distribution ranging from the the middle and lower Danube River system and its tributaries and other coastal rivers of the Black Sea and the Caspian Sea, to the rivers of the Caucasus, northern Greece, and the northern Aegean islands. In the Black Sea region this species is found in Bulgaria (Haskovo, Varna, Burgas, Lovec, and Plovdiv Provinces), Ukraine, Crimea, Caucasia (= Georgia, Armenia, and Azerbaijan). This species is also found in the region to the south of the Caspian Sea region in Turkmenistan (Maurakis et al., 2004) and Iran (Mazandaran, Province). In Turkey, this species is found both in the European part (Erdine, Kirklareli, and Tekirdag Provinces), and the Asian parts in the Provinces of Canakkale, Balikesir, Bursa, Bilecik, Sakarya, Ankara, and Rize. In Greece, Potamon ibericum occurs in Macedonia and the northeastern mainland part of Greece east of the Axios River to the Evros River at the Greece-Turkey border in Hevros,Thessaloniki, and Makedonia Provinces. Potamon ibericum is also found in the northeastern Aegean region on the islands of Thassos (Kavala Province), Samothraki, Chios (Chios Province), and Lesbos (Lesbos Province). The populations of this species in southern France from the Herault River near St. Guilhem le Desert, 350 km west of Nice are thought to be relatively recent introductions to France via human activity rather than representing relict populations that reached this location by natural means. Although the name might imply that P. ibericum occurs in the Iberian Peninsula, it is not found in either Spain or Portugal, and there are no species of true freshwater crabs in either of these countries.
