Thylamys is a genus of opossum in the family Didelphidae. The premaxillae are rounded rather than pointed. The females lack a pouch. The females' nipples are arranged in two symmetrical rows on the abdomen[2] All species but T. macrurus store fat in their tails.,[3] although this is not necessarily true for all species in the genus.[4]
The genus contains the following species:
- Cinderella fat-tailed mouse opossum (Thylamys cinderella)
- (Thylamys citellus) [5]
- Elegant fat-tailed mouse opossum (Thylamys elegans)
- (Thylamys fenestrae) [6]
- Karimi's fat-tailed mouse opossum (Thylamys karimii)
- Paraguayan fat-tailed mouse opossum (Thylamys macrurus)
- White-bellied fat-tailed mouse opossum (Thylamys pallidior)
- (Thylamys pulchellus) [7]
- Common fat-tailed mouse opossum (Thylamys pusillus)
- Argentine fat-tailed mouse opossum (Thylamys sponsorius)
- Tate's fat-tailed mouse opossum (Thylamys tatei)
- Dwarf fat-tailed mouse opossum (Thylamys velutinus)
- Buff-bellied fat-tailed mouse opossum (Thylamys venustus)
Fossils belonging to the genus date back to the Miocene, with the oldest specimens being found in Argentina and Colombia.[8] Genetic studies indicate that the genus may have originated around 14 million years ago.[9]
