The pleasant bolo mouse, or pleasant akodont, (Necromys amoenus) is a species of rodent in the family Cricetidae. [2] It is found on grassland at high altitudes in Bolivia and Peru.
The pleasant bolo mouse is a small member of its genus with a head-and-body length of between 95 and 103 mm (3.7 and 4.1 in) and a tail of 63 and 79 mm (2.5 and 3.1 in). The back and upper parts have yellowish-brown fur intermixed with some black hairs. The muzzle, cheeks and sides of the body are yellowish-buff, and the underparts are whitish. There is often a clear demarcation between the different regions, and the belly contrasts strongly with the upper regions. The whiskers are short, the ears rounded and well-furred and the tail is blackish-brown or ochre-brown above, and white below. The paws are covered with ochre-brown hairs above and the nails are concealed in bushy tufts of hair. [3]
The pleasant bolo mouse is found in the Andean Plateau of west-central South America, in western Bolivia and southeastern Peru. It is present in the altiplano grasslands at altitudes between about 3,200 and 4,300 m (10,500 and 14,100 ft). [1] It is also reported from the eastern side of the Andes on slopes in Salta Province, Argentina. It can be found near rocky outcrops and in sparsely-grassed area with scattered rocks, particularly in areas where the Peruvian feathergrass (Jarava ichu) and Parastrephia lepidophylla predominate. [3] It is also found in Polylepis woodland and cultivated areas in Bolivia and seems tolerant of disturbance to its habitat. [1]
The pleasant bolo mouse is diurnal and seems to feed mostly on insects. [3]
Necromys is a genus of South American sigmodontine rodents allied to Akodon. This genus has also been known as Cabreramys or more recently Bolomys, and the northern grass mouse has recently been transferred from Akodon.
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.
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 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 hairy-eared cerrado mouse or hairy-eared akodont, is a rodent species from South America. It is found in the cerrado grassland of Brazil.
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 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 rufous-bellied bolo mouse or white-chinned akodont, is a species of rodent in the family Cricetidae. It is found in Argentina and Bolivia where it inhabits the dry valleys of the eastern Andes. Its conservation status is listed by the International Union for Conservation of Nature as being of "least concern".
The dark bolo mouse or dark-furred akodont is a species of rodent in the family Cricetidae. There are two subspecies; one is found in eastern and central parts of Buenos Aires Province, Argentina, and the other in coastal areas of southern Uruguay.
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.
Mittendorf's lemniscomys or Mittendorf's striped grass mouse is a species of rodent in the family Muridae. It is endemic to Cameroon where it is found at high elevations on a single mountain. Its natural habitat is tropical high-altitude grassland. It faces no particular threats and the International Union for Conservation of Nature has listed it as being of "least concern".
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.
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 Huanchaca mouse or Huanchaca akodont is a rodent species in the family Cricetidae. It is known from savannas in an area at an elevation of 700 metres (2,300 ft) in Serrania Huanchaca, Noel Kempff Mercado National Park in eastern Bolivia.
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.
