This work reports for the first time in Spain the presence of the non-native salmonid Alpine charr, usually included into Salvelinus alpinus, but recently revised to Salvelinus umbla. The species was found in a high mountain lake in the Pyrenees belonging to the Garonne catchment (Lake Obago, Val d’Aran, province of Lleida). This is probably not a recent introduction since the presence of one species of Salvelinus in some lakes of the Val d’Aran has been known among anglers for a long time, but the species identification was lacking. The distribution of S. umbla in the Val d’Aran appear to be restricted to a very few lakes and it has not spread downstream.
