Resum

New records of Rutilus arcasii (Steindachner, 1866) (Ostariophysi, Cyprinidae) in Spain
Rutilus arcasii is firstly reported from the Spanish river basins: Marín (Atlantic slope) and Francolí, Mijares, Palancia and Serpis (Mediterranean slope). Otherwise, specimens from the Guadiana river basin recorded previously were studied and determined as Rutilus lemmingii (Steindachner, 1866). Therefore, the distribution of Rutilus arcasii is limited to the basins of the rivers Ulla, Umia, Marín, Mino, Duero, Tajo, Francolí, Ebro, Mijares, Palancia, Júcar and Serpis.
