This climbing mouse is found mainly in Brazil's Cerrado. It has a short tuft of hair at the end of its long tail, and records also note refuge use in rural houses in some habitats.
The tail is about 1.2 times the head-and-body length and ends in a 5–15 mm tuft. The back ranges from gray-brown to reddish, with a sharp boundary against the white to cream belly.
In Brazil's Cerrado, it inhabits gallery forest, cerradão woodland, and semideciduous forest. Accounts cited by the guide also report use of rural houses as refuges.
