ABSTRACT ? SYSTEMATIC AND TAXONOMIC REVISION OF THE GENUS SCELIDOTHERIUM OWEN, 1839 (XENARTHRA, PHYLLOPHAGA, MYLODONTIDAE). The subfamily Scelidotheriinae (Xenarthra, Phyllophaga, Mylodontidae) has been recorded since the ?Friasian? sensu lato (middle Miocene) to Lujanian (late Pleistocene - early Holocene). For the Quaternary four genera: Scelidotherium, Valgipes, Scelidodon and Catonyx are recognized and recorded in Argentina, Bolivia, Chile, Ecuador, Peru and Uruguay. The authors performed a systematic and taxonomic study of the genus Scelidotherium Owen of Argentina. Two valid species are recognized: (i) S. bravardi Lydekker presents records in the provinces of Buenos Aires during the Ensenadan (ca. 1 My - 0.4 My BP; early Pleistocene - middle Pleistocene) and in the Pleistocene of the province of San Luis, and (ii) S. leptocephalum Owen presents records during Bonaerian and Lujanian (ca. 0.4 My - 8.5 ky BP; middle Pleistocene - early Holocene) in the Province of Buenos Aires, in the Lujanian of the provinces of Córdoba, Corrientes, Salta y Formosa; outside argentine territory S. leptocephalum is recorded in the late Pleistocene of Uruguay.
