RT Journal Article SR Electronic T1 Elevational and latitudinal range extensions of the puna mouse, Punomys (Cricetidae), with the first record of the genus from Chile JF bioRxiv FD Cold Spring Harbor Laboratory SP 2023.03.07.531530 DO 10.1101/2023.03.07.531530 A1 Marcial Quiroga-Carmona A1 Jay F. Storz A1 Guillermo D’Elía YR 2023 UL http://biorxiv.org/content/early/2023/03/10/2023.03.07.531530.abstract AB 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’) in the caldera of Volcán Acamarachi, Región de Antofagasta, Chile. Results of a morphological 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.Competing Interest StatementThe authors have declared no competing interest.
