Abstract

We report an elevational record for the Andean sigmodontine Puna Mouse Punomys, which is also the first record of the genus in Chile. The record is based on a mummified specimen that we discovered at an elevation of 5,461 m (17,917 feet) in the caldera of Volcán Acamarachi, Región de Antofagasta, Chile. Results of a morphological assessment suggest that the specimen can be provisionally referred to the species P. lemminus. This new record also extends the known geographic distribution of the genus by 700 km to the south and brings the known Chilean mammal richness to a total of 170 living species and 88 genera. This finding highlights the need for increased survey efforts in more remote, high-elevation regions and demonstrates that there is still much to be learned about the mammal fauna of the Andean Altiplano.

Se reporta un registro altitudinal para el roedor sigmodontino Punomys, el cual corresponde a su vez al primer hallazgo del género para Chile. Este se basa en un espécimen momificado encontrado a una elevación de 5,461 m en la caldera del Volcán Acamarachi, Región de Antofagasta, Chile. Los caracteres morfológicos sugieren que el espécimen puede ser referido provisionalmente a la especie P. lemminus. Este nuevo registro amplía la distribución geográfica conocida del género en 700 km al sur, y eleva la riqueza de mamíferos vivientes chilenos a un nuevo total de 170 especies y 88 géneros. Este hallazgo resalta la necesidad de aumentar los esfuerzos de prospección en las regiones más remotas y de mayor altitud y demuestra que aún queda mucho por aprender sobre el ensamble de los mamíferos del Altiplano andino.
