Heteromyidae

The family of rodents that include kangaroo rats, kangaroo mice and pocket mice is Heteromyidae. Most heteromyids live in complex burrows within the deserts and grasslands of western North America, though species within the genera Heteromys and Liomys are also found in forests and extend down as far as northern South America. They feed mostly on seeds and other plant parts, which they carry in their cheek pouches[1] to their burrows.[2]

Although they are very different in physical appearance, the closest relatives of the heteromyids are pocket gophers in the family Geomyidae.

Taxonomy [edit]

Hafner et al. (2007)[3] summarized the molecular and morphological data to date and proposed the following taxonomy:

Heteromyidae
Dipodomyinae

Dipodomys



Microdipodops





Heteromys


Perognathinae

Perognathus



Chaetodipus





Most authorities prior to this (Alexander and Riddle, 2005; Patton, 2005) treat Liomys as a distinct genus from Heteromys.
