Micoureus constantiae (Thomas, 1904)

The white-bellied woolly mouse opossum, Marmosa constantiae, is a small pouchless marsupial of the family Didelphidae.[2] It is arboreal and nocturnal and inhabits moist forests in eastern Bolivia, the Brazilian State of Mato Grosso, and northwestern Argentina. The main components of its diet are probably insects and fruits, but it may also eat small rodents, lizards, and bird eggs. It was formerly assigned to the genus Micoureus, which was made a subgenus of Marmosa in 2009.[3]
