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
