The first new cave loach, Cobitis damlae, is caught from the Dalaman river drainage which is flowing in to the karstic plain of Western Turkey. There are caves, Keloğlan and Aslanini I and II in Dodurgalar province, con- nected with Dalaman river drainage c.a. 30 km. north of the catchment area. The new species probably passed through the surface water because of a heavy rain a week before we caught it. Cobitis damlae differs from its congeners by its mouth structure, fin rays formula, body without pigment, vestigial eyes.
