Kirchner's viscacha rat or Kirchner's vizcacha rat (Tympanoctomys kirchnerorum) is a species of rodent in the family Octodontidae described in 2014. [2] It is one of three species in the genus Tympanoctomys . [2] [3] That species is endemic to Chubut Province in the central western Argentina, where it has a fragmented range. Its natural habitat is desert scrubland, dunes and salt flats, where it eats halophyte plants. It is a solitary, nocturnal rodent that constructs large mounds with complex burrows. [2] The species was named in honor of both Cristina Fernández de Kirchner and Néstor Kirchner, presidents of Argentina.

<i>Abrocoma</i> Genus of rodents

Abrocoma is a genus of abrocomid rodents found in the Andes of South America, from southern Peru to central Chile. The genus contains eight species, most of which are found in isolated mountain ranges in northwestern Argentina. The oldest fossil record for the Caviomorpha appears at the late Eocene-Early Oligocene transition.

The golden viscacha rat or golden vizcacha rat is the single species of the genus Pipanacoctomys of the rodent family Octodontidae. It has 92 chromosomes and has been regarded as tetraploid. This octodontid and its sister-species, the plains viscacha rat, may have arisen from the diploid mountain viscacha rat, as a result of the doubling and subsequent loss of some chromosomes. However, some genetic studies have rejected any polyploidism in mammals as unlikely, and suggest that amplification and dispersion of repetitive sequences best explain the large genome size.

The aquatic rat, Ecuador fish-eating rat, fish-eating rat or Ecuadoran ichthyomyine is a South American species of semiaquatic rodent in the family Cricetidae. It is the only species in the genus Anotomys. This species is currently considered endangered. It is thought to be nocturnal and feeds on aquatic arthropods and insects. It is found in small ranges along the Andes.

Pittier's crab-eating rat is a species of semiaquatic rodent in the family Cricetidae. It is endemic to Venezuela. The natural habitats of this species are rivers and swamps. Its karyotype has 2n = 92 and FNa = 98. This was previously thought to be the highest chromosome number known for a mammal, but it has since been found that the plains viscacha rat or red viscacha rat has 4x = 2n = 102.

<i>Tympanoctomys</i> Genus of rodents

Tympanoctomys is a genus of rodent in the family Octodontidae. There are three extant species in the genus: T. barrerae, T. kirchnerorum and T. loschalchalerosorum. T. loschalchalerosorum was formerly considered to be monotypic within the genus Salinoctomys, but has been shown by genetic analysis to nest within the variation of T. barrerae.

Viscacha rats are a group of rodents in the family Octodontidae. All species are found in Argentina. They are placed in the following genera:

<span class="mw-page-title-main">Octodontidae</span> Family of rodents

Octodontidae is a family of rodents, restricted to southwestern South America. Fourteen species of octodontid are recognised, arranged in seven genera. The best known species is the common degu, Octodon degus.

The Chalchalero viscacha rat or Chalchalero vizcacha rat is a species of caviomorph rodent in the family Octodontidae. It was formerly considered to be monotypic within the genus Salinoctomys, but has been shown by genetic analysis to nest within Tympanoctomys, and in particular, within the variation of T. barrerae. The species is endemic to a small area of northwestern Argentina, where it lives in shrublands bordering the salt flats of the Salinas Grandes. Its diet consists of halophyte plants. It is named after an Argentine musical group, Los Chalchaleros, whose songs were popular with its discoverers.
