A new species of canid (Eucyon debonisi n. sp.) is described from the late Miocene of Venta del Moro (Valencia, Spain). The new species is smaller than all the other Eucyon species, excepting E. intrepidus from the late Miocene of Lukeino (Kenya). Eucyon debonisi n. sp. is characterized by the greater size of the M2 in relation with the M1, showing comparable morphology with E. monticinensis, but this new species has a stronger parastyle, a less developed lingual cingulum and a more closed valley in the talon of the M1. Besides, it has a more slender dentition and mandible than E. monticinensis and possesses a diastema between p1 and p2 and between p2 and p3. Excepting the problematic Cants cipio from the middle Turolian locality of Concud (Spain), E. debonisi n. sp. represents the first modern canid that reached western Europe.
