Argentine fat-tailed mouse opossum
The Argentine fat-tailed mouse opossum (Thylamys sponsorius) was formerly considered a species of opossum in the family Didelphidae.[3] However, mitochondrial DNA sequence analysis does not support separate species status from T. cinderella.[1][4]
It is found in the eastern foothills of the Andes in northern Argentina and southern Bolivia.[5] Typically reach around 10-13 cm (4-5 inches) in body length, with a bushy tail adding another 12-15 cm (5-6 inches). Its dorsal fur is gray brown to dark brown. Its ventral fur is gray-based except for the white to yellowish chest hairs. It has been distinguished from T. cinderella by its well-developed postorbital ridges in both juveniles and adults that extend laterally behind the eye sockets.[6] Only adults of T. sponsorius have fully developed postorbital ridges, and these do not extend laterally behind the eye sockets.[6] While the American Society of Mammalogists maintains this as a distinct species,[7] mitochondrial DNA sequence analysis does not support the population being distinct from T. cinderella.[1][4]
