Draft:List of octodontids

Common degu (Octodon degus)

Octodontidae is a family of small rodents restricted to southwestern South America. A member of this family is called an octodontid. Octodontids are medium-sized rodents, ranging from 12 to 20 centimetres (4.7 to 7.9 inches) in body length. They have long, silky fur, which is typically brownish in color and often paler on the underside. The name 'octodont' derives from the wear pattern of their teeth, which resembles a figure 8. Most are nocturnal, social, burrowing animals, though the degu is largely diurnal. They are herbivorous, eating tubers, bulbs, and cactuses.

There are 14 extant ochotonid species contained within 7 genera: Aconaemys (Andean rock rats), Spalacopus, Octodon (typical degus), Octodontomys, Octomys, Pipanacoctomys, and Tympanoctomys. Many extinct Octodontidae species have been discovered, with identification and classification of new discoveries still ongoing.

IUCN Red List categories

Conservation status
EX	Extinct (0 species)
EW	Extinct in the wild (0 species)
CR	Critically Endangered (3 species)
EN	Endangered (0 species)
VU	Vulnerable (1 species)
NT	Near threatened (2 species)
LC	Least concern (5 species)
Other categories
DD	Data deficient (3 species)
NE	Not evaluated (0 species)

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 ochotonid's range is provided. Ranges are based on the IUCN Red List for that species unless otherwise noted. All extinct species or subspecies listed alongside extant species went extinct after 1500 CE, and are indicated by a dagger symbol "†".

Classification

The family Octodontidae consists of fourteen extant species in seven genera which are divided into several extant subspecies. This does not include hybrid species or extinct prehistoric species. The cladogram below is based on that produced by Kelt et al., 2007. Family Ochotonidae

• Genus Aconaemys: three species
• Genus Spalacopus: one species
• Genus Octodon: five species
• Genus Octodontomys: one species
• Genus Octomys: one species
• Genus Tympanoctomys: three species
• Genus Pipanacoctomys: one species

The following classification is based on the taxonomy described by Mammal Species of the World (2005), with augmentation by generally accepted proposals made since using molecular phylogenetic analysis, as supported by both the IUCN and the American Society of Mammalogists.
