Southern grasshopper mouse Onychomys torridus, from the National Park Service.

Belongs within: Myomorpha.
Contains: Democricetodon, Tylomyinae, Sigmodontinae, Cricetini, Arvicolinae, Neotoma, Peromyscini.

The Cricetidae include the hamsters (Cricetini) of the Old World, together with the New World rats and mice and the voles of the Arvicolinae. The family is poorly defined morphologically, but members have a biserial arrangement of the molar cusps, with a longitudinal connection among them and a discrete anterocone on the first molars (Wilson 2005). The diverse New World rats and mice are divided between the subfamilies Neotominae, Tylomyinae and Sigmodontinae. The Neotominae are a primarily North American group of mice, supported as a clade by molecular data (Reeder et al. 2006). Phylogenetic analysis has supported the division of the neotomines between four tribes, with the woodrats of the Neotomini possibly the most divergent from other neotomines. Members of the Neotomini include the diminutive woodrats Nelsonia, two species of medium-sized rodents found in pine and oak forests in Mexico. The golden mouse Ochrotomys nuttalli is a golden-brown to orange-coloured, semi-arboreal mouse found in the southeastern United States. The Baiomyini, found in southern North and Central America, include the pygmy mice Baiomys and the singing mice Scotinomys. Both genera produce audible staccato ‘songs’, of longer duration in Scotinomys than Baiomys. Ther Peromyscini include the deer mice of the genus Peromyscus, the harvest mice of the genus Reithrodontomys and related taxa. The grasshopper mice of the genus Onychomys are carnivorous, feeding primarily on insects, and are noted for their speed which allows them to successfully attack venomous prey such as centipedes or scorpions.

Of more uncertain relationships are the Afrocricetodontinae of the Miocene of Africa, generally treated as an extinct group though Lavocat (1978) regarded the recent Madagascan genus Macrotarsomys as a direct derivative of the afrocricetodontine genus Paratarsomys.
