Geocapromys is a genus of rodent belonging to the hutia subfamily [1] and are currently only found on the Bahamas and Jamaica. [2] However, they formerly ranged throughout the Caribbean, from Cuba to the Cayman Islands to even islands off mainland Central America.

Systematics

The genus Geocapromys comprises five recent species, three of which are extinct. [3]

In addition, there are two species, G. megas and G. pleistocenicus , which are known only from fossil remains.

Phylogeny

Within Capromyidae, Geocapromys is the sister group to a clade comprising Mesocapromys and Mysateles on the one hand, and Capromys on the other hand. In turn, these four genera belong to the tribe Capromyini, and are the sister group to Plagiodontia.
