The underparts vary in colour between individuals, being white, red, or some shade in between.

[2] The squirrel is known to inhabit the eastern slopes of the Andes in central Peru, from Huánuco in the north to Ayacuchco and Cusco in the south, although it may also live further east, perhaps as far as the Bolivian border,[2] and further north, with one specimen collected in 1920 known from Zamora-Chinchipe Province of Ecuador.

[3] Within this region it inhabits both lowland rainforests and higher, montane, forests.

They are known to be diurnal and arboreal, and are often seen in small groups, suggesting that they are not strongly territorial.

They are thought to be relatively numerous, and to tolerate human activity such as logging and hunting better than some other squirrels, but their limited range has led to them being classified as "Vulnerable" by the Peruvian Ministry of the Environment.
