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.
