Abstract

GUZMAN, Jonathan A.  and  SIELFELD, Walter. A new northern distribution limit of Abrocoma bennettii (Rodentia, Abrocomidae) in the coastal Atacama desert, Paposo, north of Chile. Mastozool. neotrop. [online]. 2011, vol.18, n.1, pp.131-134. ISSN 0327-9383.

Abrocoma bennettii is a relatively robust abrocomid rodent endemic to Chile.  It is distributed from approximately 27°18'S - 70°25'W in the north (Atacama) to 36°00'S - 73°7'W in the south (BíoBío). We report the finding of a cranium in excellent conditions, which is the first record of this species in the coastal shrubby Mediterranean desert of the Antofagasta Region.  The record of A. bennettii in the locality of Paposo (25º00'S - 70º27'W; 648 m) represents an extension of about 280 km to the northeast of its previously known distribution in the Atacama Region of Chile.
