Range extension of Tympanoctomys barrerae (Lawrence 1941) (Rodentia: Octodontidae) in Patagonia and southernmost record

We report the southernmost record for the octodontid rodent T. barrerae, which is also the second recording locality for this species in Patagonia. The new locality is placed in S Neuquén province (39º12´37.5"S, 70º3´32.9"W), extending the known range of the species about 150 km SW from the nearest previous record. Although T. barrerae is considered a highly specialized rodent of salar flats in Monte desert, the record reported here came from an arbustive rocky environment belonging to the Monte-Patagonia ecotone.
