This Andean mouse occurs in Colombia’s Eastern Cordillera and was also recorded in the Tamá Mountains of western Venezuela. The Venezuelan record is based on one juvenile female collected in cloud forest in 1968.
The species diagnosis describes orange-rufous dorsal fur with a faint dark band along the midline, orange-buff underparts, and a uniformly dark-brown tail.
The Venezuelan specimen was collected in Andean evergreen cloud forest at 2,400 m in Táchira. It was one juvenile female collected in 1968.
