We report an elevational record for the Andean sigmodontine Puna Mouse , 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 . 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.
我们报告了安第斯鼠科普纳鼠的海拔记录，这也是该属在智利的首次记录。该记录基于我们在智利安托法加斯塔大区阿卡马奇火山口海拔5461米（17917英尺）处发现的一具木乃伊化标本。形态学评估结果表明，该标本可暂归为该物种。这一新记录还将该属已知的地理分布向南扩展了700公里，并使智利已知的哺乳动物丰富度达到170个现存物种和88个属。这一发现凸显了在更偏远的高海拔地区加大调查力度的必要性，并表明安第斯高原的哺乳动物区系仍有许多有待了解之处。
