Resumen
First record of Mylodontinae (Tardigrada, Mylodontidae) from the Huayquerian (LateMiocene) of Buenos Aires province, Argentina. The Mylodontinae (Xenarthra, Mylodontidae) are well representedin the late Miocene (Chasicoan-Huayquerian) and Pliocene (Montehermosan-Chapadmalalan) of SouthAmerica (with more of a dozen of genera recognized). For the Huayquerian Stage/Age of Argentina the diversityis high (about ten species documented). However, there are not certain records of the subfamily in the BuenosAires province during the Huayquerian. In this work are described new remains of a Mylodontinae assignable tocf. Simomylodon Saint-André, Pujos, Cartelle, De Iuliis, Gaudin, McDonald & Mamani Quispe, which come fromthe early Huayquerian of the locality of Arenas Blancas (lower course of Chasicó creek, Buenos Aires province)and constitute the first certain record of a Mylodontidae Mylodontinae for the Huayquerian in this province.Simomylodon was recorded in the Neogene of Bolivia, so the probable presence of this genus in the Buenos Airesprovince increases notably their geographic distribution.
