A spiny rat from inland South America, including dry forests. Its reddish or yellowish back is mixed with dark-brown hairs, its belly is white, and its tail is sparsely haired.
The back is pale reddish to yellowish brown, mixed with dark-brown hairs. The belly is white, and short hairs sparsely cover the scaly tail.
Observations in Bolivian dry forest report it nesting in holes in termite mounds and in armadillo burrows.
The tail is relatively short, averaging about 60–63% of head-body length in the samples described.
The upper surfaces of the hindfeet are usually white, but may be dark or divided into dark and white areas.
