Australidelphia

Australidelphia is a superorder of marsupials encompassing about three-quarters of all living marsupial species, including all those native to Australasia and one South American species, the monito del monte. Australidelphia's lineage emerged in South America, with genetic evidence indicating that the South American monito del monte is sister to all other members of the superorder, unlike other American marsupials, which belong to the Ameridelphia.
