Lindbergh's grass mouse is a small rodent studied in grasslands and wetland margins in southeastern Brazil. Its back is reddish brown, with vivid orange bands in the hairs.
The dorsal coat is reddish brown, strengthened by vivid orange bands in the hairs. The paper distinguishes this from the paler, grayer coat of a related species.
Study captures were most common in open grassy habitats with scattered shrubs and near swamps. Abundance peaked in the dry season, while reproductive activity was recorded mainly in the rainy season at one study site.
An extinction-risk assessment has not been added yet.
