This species is widely distributed throughout the eastern Iberian peninsula, as well as the Balearic islands. It is also present in Libya and Tunisia.^[2] The small streams and rivers in which it is typically found tend to be mineralized, with silt or clay substrate, and sparse riparian vegetation. It prefers shallow, slow moving, clean, well oxygenated water. It can occasionally be found in eutrophic waters.^[1]
