%X The North African freshwater fish fauna is scarce compared to other regions of the world, probably due to historical and climatic factors. The western part of North Africa is more diverse than central or eastern areas. Populations of freshwater blennids that have been traditionally ascribed to the species Salaria fluviatilis nowadays inhabit the Sebou basin in Morocco. In this study we demonstrated morphologically and molecularly that these Moroccan populations constitute a new species, for which we provide a formal description. The following diagnostic characters distinguish the newly described species from other freshwater blennids: head without diagonal rows of dark dots or blotches on cheeks; supra-ocular tentacle thick and simple (not branched); 13-15 teeth on the upper jaw and 14-16 on the lower jaw; 16-17 soft anal fin rays; short pre-orbital distance (cephalic index: 2.9-3.8); height of the anterior (spiny) part of the dorsal fin short (dorsal fin index: 0.8-1.3) and 34 vertebrae. Mitochondrial and nuclear genetic distances between the new Salaria species and either S. economidisi or S. fluviatilis are high, especially in the mitochondrial control region (18%), while these genetic distances range from 2 to 3% when the nuclear S7 marker is compared. These morphological and molecular characters differentiate the new species from the remaining freshwater species of the genus (Salaria economidisi and S. fluviatilis). The new species is confined to a small restricted area of the Sebou basin in Morocco and should be considered endangered (EN) according to the IUCN Red List. La fauna de peces de agua dulce del norte de ¨¢frica es escasa comparada con otras regiones del mundo debido fundamentalmente a factores hist¨®ricos y clim¨¢ticos. El oeste del norte de ¨¢frica es m¨¢s diverso que las regiones del centro y del este. En la cuenca del r¨ªo Sebou habitan actualmente poblaciones de blenios de agua dulce que han sido tradicionalmente adscritas a la especie Salaria fluviatilis. En este estudio demostramos morfol¨®gica y molecularmente que estas poblaciones marroqu¨ªes constituyen una nueva especie, para la cual proveemos una descripci¨®n formal. Los siguientes caracteres diagn¨®sticos distinguen a la nueva especie descrita del resto de especies de blenios de agua dulce: cabeza sin una fila diagonal de puntos oscuros o manchas en las mejillas; tent¨¢culo supraocular grueso y simple (no ramificado); 13-15 dientes en la mand¨ªbula superior y 14-16 en la inferior; 16-17 radios blandos en la aleta anal; distancia preorbital corta (¨ªndice cef¨¢lico: 2.9-3.8); altura de la
