The Southern naked-tailed armadillo (Cabassous unicinctus), is a species of armadillo from South America. It is found in Colombia, Ecuador, Venezuela, Peru, Bolivia and Brazil. It is a solitary nocturnal and terrestrial animal, living in many habitats from rainforest to grassland. As are many armadillos, it is an insectivore, feeding on ants and termites. It digs burrows with an entrance of about 16 cm diameter; these are used for only one night then abandoned.
