Neacomys minutus, also known as the minute neacomys, [2] the small bristly mouse, [3] or the minute spiny mouse, [4] is a rodent species from South America in the genus Neacomys . It is found in Brazil.
A small mouse, Neacomys minutus has a head-and-body length of 65 to 79 mm (2.6 to 3.1 in) and a tail of 68 to 90 mm (2.7 to 3.5 in). The upper parts are clad in rather coarse fur which is dark orangish-brown and finely grizzled with black; the underparts are pale and there are short, grooved spines mixed in with the fur. The tail is sparsely haired and is bicoloured, being dark above and pale beneath. The ears are small and rounded, and the hind feet are slender and have naked soles, the central three of the five claws being considerably longer than the outer ones. [4]
N. minutus is found in the Amazon basin in western Brazil and eastern Peru. Its range includes the middle and lower basin of the Juruá River in Amazonas State, and the adjoining part of Loreto Region in Peru. Its habitat is the seasonally flooded moist broadleaf várzea forest and the drier, upland, terra firme forest. [4]
Breeding takes place in both the dry and the wet season, and seems to start at a young age, as some reproductively active individuals still have unworn teeth and have not fully shed their juvenile fur. The average litter size is three; one female was found to be both pregnant and lactating. It shares its range with Neacomys spinosus but is replaced in the upper parts of the Juruá basin by Neacomys musseri . [4]
This mouse has a very wide range and is assumed to have a stable population. It is probably able to tolerate some degree of habitat modification and it occurs in at least two protected areas, so the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".

The long-tailed spiny rat, Proechimys longicaudatus, is a spiny rat species from South America. It is found in Bolivia, Brazil and Paraguay.
Euryoryzomys nitidus, also known as the elegant oryzomys or elegant rice rat, is a rodent species in the family Cricetidae. Previously it was known as Oryzomys nitidus, but it is not closely related to Oryzomys as that genus is now constructed. Its range includes Bolivia, Brazil and Peru to the east of the Andes, in lowland tropical rainforest as well as forest in the eastern foothills of the mountains, at elevations from 50 to 2,000 m.
Oligoryzomys microtis, also known as the small-eared colilargo or small-eared pygmy rice rat, is a species of rodent in the genus Oligoryzomys of family Cricetidae. It is found in western Brazil, eastern Peru, Bolivia, and northern Paraguay.
Neacomys spinosus, also known as the common neacomys, common bristly mouse, or bristly mouse, is a nocturnal rodent species from South America in the genus Neacomys. It is found in Bolivia, Brazil, Colombia, Ecuador and Peru, where it often lives in transition areas between lowland forest and open regions. Its diet consists of insects, seeds and fruit.
The Amazonian hocicudo is a species of rodent in the family Cricetidae from South America. It is found in the Amazon basin in Brazil where it lives in moist lowland forest. It is a common species with a large range and is rated by the IUCN as being of "least concern".
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 cerrado mouse is a rodent species from South America. It is found in the cerrado of Brazil.
The northern grass mouse, or northern akodont, is a species of rodent in the family Cricetidae. It is found in Brazil, Colombia, Venezuela and Trinidad and Tobago.
The spotted bolo mouse or Ecuadorian akodont is a species of rodent in the family Cricetidae. It is known from Ecuador and may also occur in Colombia. Little is known of its status and range.
Microryzomys altissimus, also known as the Páramo colilargo or highland small rice rat, is a species of rodent in the genus Microryzomys of family Cricetidae. It is found in Colombia, Ecuador, and Peru, but the Colombian segment may be a separate species.
Microryzomys is a genus of rodent in the tribe Oryzomyini of family Cricetidae. It is closely related to Oreoryzomys, Oligoryzomys, and Neacomys. It contains two species, both restricted to the Andes: M. altissimus and M. minutus.
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 Ethiopian white-footed mouse or white-footed stenocephalemys is a species of rodent in the family Muridae. It lives in Ethiopia and Eritrea. Its natural habitats are tropical moist montane forest and tropical high-altitude shrubland.
The little desert pocket mouse is a species of small rodent in the family Heteromyidae. It is endemic to Baja California in Mexico.
Goldman's pocket mouse is a species of rodent in the family Heteromyidae. It is endemic to Mexico, where it is threatened by the increasing conversion of its dry, scrubby habitat into agricultural land. As a result, the International Union for Conservation of Nature has assessed its conservation status as being "near threatened".
The Paraguayan bolo mouse or Paraguayan akodont is a species of rodent in the family Cricetidae. According to the IUCN, it is present in Bolivia, Paraguay, and Peru, and possibly also in Argentina and Brazil. It is found at elevations from 300 to 2,030 m in a variety of habitats, including cerrado, chaco, and heath pampas.
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.
