Heteromys
Heteromys is a genus of rodents in the family Heteromyidae, commonly known as spiny pocket mice. It is the only single extant genus in the subfamily Heteromyinae which also includes the extinct genera Diprionomys and Metaliomys. Heteromys was recently enlarged by inclusion of the members of formerly recognized heteromyine genus Liomys, which was found to be paraphyletic.
