The Junin slender opossum (Marmosops juninensis) is a species of South Americanopossum in the family Didelphidae.[2] It is known only from the valley of the Chanchamayu in Peru (a range that includes Junín Region) where it lives in Andeanmontane forests at elevations between 1460 and 2200 m.[1] The species is threatened by destruction of its forest habitat as the area under cultivation in the region increases.[1]
