Map of Thylamys in South America
Diagram from "Phylogenetic and biogeographic relationship of the mouse opossum Thylamys (Didelphimorphia, Didelphidae) in southern South America" by R. Eduardo Palma, Eric Rivera-Milla, Terry L. Yates, Pablo A. Marquet, and Andres P. Meynard (05/07/2002)
"Thylamys" is frequently confused with "Marmosa". "Marmosa elegans" instead of "Thylamys elegans" is a particularly common mistake. Thylamys was a subgenus for Marmosa elegans according to Thomas in the 1920s. Tate (1933) made five species groups - cinera, microtarsus, murina, noctivaga and elegans. Gilmore (1941) referred to a Thylamys subgenus. Goatherd (1958) used Thylamys to define a subgenus of Marmosa. Creighton (1984) took the Thylamys group of Tate (1933) and made it a genus. In 1989, Gardner and Creighton defined the genus Marmosops as the Tate (1933) group "noctivaga" and defined the genus Gracilinanus as the Tate (1933) microtarsus section of the group "microtarsus".
