First record of Banderomys leanzai Kramarz, 2005 (Rodentia, Caviomorpha) in Chubut Province, Patagonia (Argentina)

Cephalomyidae was established in the XIX century, and considered by different authors as a heterogeneous group of hypsodont South American hystricognath rodents. Other authors corroborated this family as a natural group among caviomorphs and recognized some taxa recorded from the Deseadan–Colhuehuapian South American Land Mammals Ages (SALMAs). Among them, Banderomys leanzai (the only species of this genus) is characteristic and exclusive of the locality of Cerro Bandera (early Miocene, Colhuehuapian?, Neuquén Province, Argentina). The aim of this work is to report the first record of B. leanzai outside the type locality; the new specimens come from the early Miocene of central Chubut Province (Patagonia, Argentina). This new finding extends the geographical distribution of the species and increases the dental morphology knowledge of B. leanzai.
