|Assessor(s):||Gómez-Laverde, M., Rivas, B. & Delgado, C.|
|Reviewer(s):||Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)|
This species is listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category. The Colombian distribution is likely to be a distinct species which may qualify for inclusion in a threat category, however, taxonomic review is required.
|Range Description:||This species occurs in the Andes of Colombia, Ecuador, and Peru, mostly 2,500 to 4,000 m (Musser and Carleton, 2005).|

|Conservation Actions:||It occurs in a number of protected areas in the southern distribution but only one in the northern distribution.|
