Notiomys edwardsii, also known as Edwards's long-clawed mouse, [1] Edward's long-clawed akodont, [2] or Milne-Edwards' long-clawed mouse, [3] is a rodent in the tribe Abrotrichini from southern Argentina. It is the only species in the genus Notiomys, although species of Chelemys and Geoxus were formerly included in that genus. [2]
Edwards's long-clawed mouse is a small mouse with a short tail, having a total length of about 137 mm (5.4 in), including a tail of about 40 mm (1.6 in). [4] The dorsal fur is dense and soft and about 8 mm (0.3 in) long, each hair having a grey shaft and being tipped with ochre, giving an agouti effect. The underparts have grey hairs tipped with white, and the two body colours are separated by grey hairs tipped with orange. The eyes are small, the snout is tipped with a pink, leathery button, and the sides of the muzzle have orange spots. The whiskers are white, the longest being about 8 mm (0.3 in) in length. The pinnae are small and rounded, the thin margins being clad in white hairs. The tail is well furred, being buffy-white above and white below. The fore feet have long nails some 4 mm (0.16 in) in length. The hind feet are short and broad, being fringed with bristly hairs at the sides, and having furred heel pads and naked soles; they have 3 mm (0.12 in) claws. [5]
The species is endemic to Santa Cruz Province, Chubut Province and Río Negro Province in southern Argentina. Its typical habitats are shrubby and herbaceous steppe, grassy steppes and rocky plateaus with shrubs and bunchgrass. [5]
The ecology of this burrowing mouse has been little studied. It mostly feeds on insects but may also consume seeds. One specimen was found inside the burrow of a Haig's tuco-tuco (Ctenomys haigi). Before 1998, only eight localities across Patagonia were known. More recently, as a result of more-intensive surveys, over fifty localities have been identified, some by finding the remains of mice in owl pellets. [5]
Edwards's long-clawed mouse has a wide range and is present in several protected areas. It is common in some places and uncommon in others, and is assumed to have a large total population. No particular threats have been identified and the population appears to be steady, so the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".

Neacomys minutus, also known as the minute neacomys, the small bristly mouse, or the minute spiny mouse, is a rodent species from South America in the genus Neacomys. It is found in Brazil.
The hairy-tailed bolo mouse or hairy-tailed akodont is a South American rodent species of the family Cricetidae. It is found in Argentina, Bolivia, Brazil, and Paraguay.
Gardner's climbing mouse is a rodent species from South America. It is found in western Brazil, southeastern Peru and northeastern Bolivia. It is an uncommon, arboreal species, but faces no particular threats so the International Union for Conservation of Nature has rated it as being a "least-concern species".
The white-footed climbing mouse is a species of South American rodent found in Bolivia, Brazil, Ecuador, French Guiana, Guyana, Peru, Suriname and Venezuela. It is the type species of the genus and the type location was the lower eastern slopes of the Andes in central Peru.
The Brazilian arboreal mouse is a South American rodent species of the family Cricetidae. It is found in the Atlantic Forest of southeast Brazil, often close to bamboo thickets. It can be distinguished from Rhagomys longilingua, the only other species in its genus, by the absence of spines among the hair. Formerly believed to be extinct after no sightings were recorded for over 100 years, the species has since been found in four localities. However, it is nowhere common, and all of these are forest fragments, and ongoing deforestation threatens the species' survival. For these reasons, the International Union for Conservation of Nature has assessed its conservation status as being "vulnerable".
Abrothrix illuteus, also known as the gray akodont, gray grass mouse, or gray soft-haired mouse, is a species of small rodent in the genus Abrothrix of family Cricetidae. It is found only in northwestern Argentina.
Abrothrix longipilis, also known as the long-haired grass mouse or long-haired akodont, is a species of rodent in the family Cricetidae. It is endemic to central Argentina and Chile. Until 2014 it was thought that the species extended into southern Chile and Argentine Patagonia but these populations are now proposed to belong to closely related species named Abrothrix hirta.
Akodon spegazzinii, also known as Spegazzini's akodont or Spegazzini's grass mouse, is a rodent in the genus Akodon found in northwestern Argentina. It occurs in grassland and forest at 400 to 3,500 m above sea level. After the species was first named in 1897, several other names were given to various populations now included in A. spegazzinii. They are now all recognized as part of a single, widespread and variable species. Akodon spegazzinii is related to Akodon boliviensis and other members of the A. boliviensis species group. It reproduces year-round. Because it is widely distributed and common, Akodon spegazzinii is listed as "least concern" on the IUCN Red List.
The Colombian forest mouse is a species of rodent in the family Cricetidae. Some authorities consider it to be the only species in the genus Chilomys, while others accept Chilomys fumeus as being a valid species, and it may form part of a species complex. It is found in Colombia, Ecuador, and Venezuela.
The montane hylomyscus or montane wood mouse is a species of rodent in the family Muridae. A long-coated species with brownish-grey upper parts and whitish-grey underparts, it occurs in the uplands of tropical Central Africa where its natural habitat is tropical moist montane forests.
The Mount Oku hylomyscus is a species of rodent in the family Muridae. Found only on Mount Oku, Cameroon, in tropical Central Africa, its natural habitat is tropical moist montane forests. It has a very small range and is threatened by habitat destruction, so the International Union for Conservation of Nature has rated its conservation status as being "critically endangered".
The Ethiopian forest brush-furred rat or golden-footed brush-furred rat, is a species of rodent in the family Muridae. It is endemic to Ethiopia where its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.
Oligoryzomys destructor, also known as Tschudi's colilargo or the destructive pygmy rice rat, is a species of rodent in the genus Oligoryzomys of family Cricetidae. It is found along the eastern Andes from southern Colombia, through Ecuador, Peru, and Bolivia into northern Argentina. Its karyotype has 2n = 60 and FNa = 76.
Oligoryzomys magellanicus, also known as the Patagonian colilargo and the Magellanic pygmy rice rat, is a species of rodent in the genus Oligoryzomys of the family Cricetidae. It is found in the southernmost parts of Argentina and Chile, including Tierra del Fuego and other outlying islands. Its karyotype has 2n = 54 and FNa = 66.
The southern climbing mouse is a species of rodent in the family Cricetidae. It is found in Argentina and Bolivia in forested valleys and on slopes on the eastern side of the Andes Mountains.
Coues's climbing mouse is a species of rodent in the family Cricetidae. It is found in Colombia, Ecuador, Peru, Trinidad and Tobago, and Venezuela. It is named in honour of the American zoologist Elliott Coues who studied birds and small mammals.
Scolomys melanops, also known as the short-nosed scolomys, South American spiny mouse, Ecuadorian spiny mouse, or gray spiny mouse, is a species of rodent in the genus Scolomys of family Cricetidae. It is a forest mouse and was thought to be endemic to Ecuador but it is now known to have a wider distribution, being also present in part of Peru.
The golden Oldfield mouse or golden thomasomys is a species of rodent in the family Cricetidae. It is found in Colombia, Ecuador, Peru, and Venezuela. Both the common and genus name commemorate the British zoologist Oldfield Thomas who worked at the Natural History Museum, London and studied South American rodents.
The long-tongued arboreal mouse is a South American rodent species of the family Cricetidae. It is found in a variety of habitats, including dense forest, in Bolivia and Peru at elevations from 450 to 2,100 metres on the eastern side of the Andes. The species is at least partly arboreal. It is distinguished from the Brazilian arboreal mouse, the only other known member of Rhagomys, by spiny fur and certain skull features such as the presence of beading in the interorbital region.
The Peruvian climbing mouse or lesser Peruvian rhipidomys, is a South American species of rodent in the family Cricetidae. It is endemic to the eastern slopes of the Andes in central Peru, where it is found at altitudes from 700 to 1,800 metres. The species is nocturnal and arboreal, and lives in lower montane forest and cloud forest. It is threatened by forest clearance for agriculture and coca cultivation but is listed as a "least-concern species" by the International Union for Conservation of Nature.
