Marmosa
The 27 species in the genus ''Marmosa'' are relatively small Neotropical members of the family Didelphidae. This genus is one of three that are known as mouse opossums. The others are '' Thylamys'' (the "fat-tailed mouse opossums") and '' Tlacuatzin'', the grayish mouse opossum. Members of the genus '' Marmosops'' used to be called "slender mouse opossums", but are now just called "slender opossums". The thirteen members of the ''Marmosa'' subgenus ''Micoureus'', known as woolly mouse opossums, were formerly considered to be a separate genus, but were moved into ''Marmosa'' in 2009. Based on a comparison of sequences of one mitochondrial and three nuclear genes, three new subgenera, ''Eomarmosa'', ''Exulomarmosa'' and ''Stegomarmosa'', were recognized by Voss ''et al.'' in 2014. ''Eomarmosa'' and ''Exulomarmosa'', as well as ''Marmosa'' and ''Micoureus'', are thought to be sister taxa, while ''Stegomarmosa'' is viewed as sister to ''Marmosa'' plus ''Micoureus''.

Marmosa Robinsoni
Robinson's mouse opossum (''Marmosa robinsoni'') is a species of opossum in the family Didelphidae. It is found in Belize, Colombia, Ecuador, Grenada, Honduras, Panama, Peru, Trinidad and Tobago, and Venezuela. Robinson's mouse opossums move along tree branches and vines with the help of a prehensile tail and may leap between gaps as they search for fruit and insects. The species is named after Wirt Robinson, the collector of the specimen from which it was first described. Description ''Marmosa robinsoni'' is typically cinnamon brown with a yellow underside. Its dorsal color varies from russet to gray. The top of the head is generally paler in color than the rest of the body. The black facial mask is always present but varies in size according to the region of that individual. It possesses a prehensile tail about 1.3 times its body length, which is covered in fine white hairs. Its feet are modified for grasping with pads and an opposable hallux.

Marmosa Mexicana
The Mexican mouse opossum (''Marmosa mexicana'') is a species of North American opossum in the family Didelphidae.

Marmosa Andersoni
The heavy-browed mouse opossum (''Marmosa andersoni''), or Anderson's mouse opossum, is a species of opossum in the family Didelphidae. It is endemic to a restricted range in southern Peru. This opossum inhabits forests; it is nocturnal and probably arboreal Arboreal locomotion is the locomotion of animals in trees. In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally (scansorial), but others are exclusively arboreal. The hab ....

Marmosa Constantiae
The white-bellied woolly mouse opossum (''Marmosa constantiae'') is a small pouchless marsupial of the family Didelphidae. It was formerly assigned to the genus '' Micoureus'', which was made a subgenus of ''Marmosa'' in 2009. The specific epithet was given in honour of Constance Sladen (née Anderson), wife of the naturalist Percy Sladen. She funded the 1902 expedition which collected the type specimen.

Marmosa Paraguayanus
Tate's woolly mouse opossum (''Marmosa paraguayana'') is an omnivorous, arboreal South American marsupial of the family Didelphidae, named by American zoologist George Henry Hamilton Tate. It is native to Atlantic coastal forests of Brazil, Paraguay and Argentina. The species lives in both primary and secondary forest, including forest fragments within grassland.

Marmosa Tyleriana
Tyler's mouse opossum (''Marmosa tyleriana'') is a South American marsupial of the family Didelphidae. It lives in rainforests of the Guiana Highlands of southern Venezuela at elevations between 1300 and 2200 m. The species has only been found on three isolated tepuis ( Auyantepui, Marahuaca and Sarisariñama). All three of these locations are in protected areas ( Canaima, Duida-Marahuaca and Jaua-Sarisariñama national parks). The Latin species name refers to the habitat in which the opossum was first found, a '' Tyleria'' forest. In turn, both the genus ''Tyleria'' and the opossum's common name refer to Sidney F.
