A small rodent broadly distributed across the Andes of Ecuador and northwestern Peru. It occupies varied habitats, including grassland, shrubland, and forest, and eats plant and insect material.
The soft coat is a mix of olive-brown and yellowish tones above, with paler fur below. The ears are short, and the short tail is darker above and greyish below.
Its diet contains varying proportions of plant and insect material. A study across Andean environments found limited skull differences in most settings, with a distinct exception among samples from high-elevation wet puna.
An extinction-risk assessment has not been added yet.
