Felis pumoides Castellanos 1958 is a Felinae of dubious stratigraphic procedence, reported as coming from Pliocene beds ("horizonte Brocherence”) from Córdoba province, Argentina. In the present paper the cranial and postcranial remains of the holotype (MUFyCA 767) were mainly compared with other South American felids and Acinonyx jubatus. Is concluded that P. pumoides possess great similarity to the recent species Puma (Herpailurus) yagouaroundi, and some shared traits with Puma (Puma) concolor and Acinonyx jubatus. These species belong to an evolutionary line well defined by previous molecular and morphological data. Therefore, the taxon should be referred as Puma (Herpailurus) pumoides n. comb. The comparisons of this species with the extinct cougar species from the Pliocene and Pleistocene of North America P. (Miracinonyx) inexpectata, and the Old World P. (Viretailurus) pardoides, as well as with the cheetahs from the Pliocene-Pleistocene of Old World, show extensive morphological similarities. Comparissons suggests a possible origin of South American puma lineage near the basal diverge of North American pumas (subgenus Miracinonyx). Ac-cording to the associated remains and previous publications it is possible to confrm that P. (H.) pumoides comes from Upper Pliocene levels ("Brocherense”). Thus, it constitutes the earlist record for the Felidae and the Puma lineage in South America. Phylogenetic affinities of P. (H.) pumoides also indicates that the line of Herpailurus originated in South America before the Pleistocene.
