List of neotomines

Neotominae is a subfamily of mammals in the rodent family Cricetidae, which in turn is part of the Myomorpha suborder in the order Rodentia. Members of this subfamily are called neotomines and include deer mice, pack rats, and grasshopper mice. They are found in North America, Central America, and northwestern South America, primarily in forests, shrublands, grasslands, and deserts, though some species can be found in rocky areas and wetlands. They range in size from the northern pygmy mouse, at 5 cm (2 in) plus a 3 cm (1.2 in) tail, to the bushy-tailed woodrat, at 25 cm (10 in) plus a 22 cm (9 in) tail. Neotomines generally eat seeds, nuts, roots, stems, leaves, and invertebrates. Almost no neotomines have population estimates, but 14 species are categorized as endangered, and 16 species are categorized as critically endangered, some with population sizes of less than 50. One species, Pemberton's deer mouse, was driven extinct in the 1900s.

The 123 extant species of Neotominae are divided into 16 genera, with almost half of the species, 56, in the Peromyscus genus. Several extinct prehistoric neotomine species have been discovered, though due to ongoing research and discoveries, the exact number and categorization are not fixed.^[1]

The author citation for the species or genus is given after the scientific name; parentheses around the author citation indicate that this was not the original taxonomic placement. Conservation status codes listed follow the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. Range maps are provided wherever possible; if a range map is not available, a description of the neotomine's range is provided. Ranges are based on the IUCN Red List for that species unless otherwise noted. All extinct species, subspecies, or genera listed alongside extant species went extinct after 1500 CE, and are indicated by a dagger symbol: "†".

Neotominae is a subfamily of the rodent family Cricetidae consisting of 123 extant species in 16 genera. These genera range in size from 1 to 56 species, with the latter, Peromyscus, comprising nearly half of the species in the subfamily. Additionally, one species, Pemberton's deer mouse in Peromyscus, was driven extinct in the 1900s.^[2] This does not include hybrid species or extinct prehistoric species.
