The hairy-eared cerrado mouse (Thalpomys lasiotis) or hairy-eared akodont, is a rodent species from South America. It is found in the cerrado grassland of Brazil.
The hairy-eared cerrado mouse has a head-and-body length of less than 90 mm (3.5 in) and is generally smaller than the only other species in the genus, the cerrado mouse (Thalpomys cerradensis). The two are similar in appearance, but the hairy-eared mouse has a more intense colour and longer, more lax fur. The dorsal pelage is reddish-brown, the individual hairs having blackish bases, orange central sections and blackish tips. There are also longer black guard hairs. The flanks and underparts are paler. The chin is buff and the eye-ring and cheeks orangish. The tail is brown above and pale beneath. The diploid number is 38. [2]
This mouse is restricted to the cerrado ecoregion in Brazil, occurring in the states of Bahia, Minas Gerais, Rondônia and São Paulo, and the Federal District. It inhabits various types of open grassland, with or without scrub, bushes and scattered trees, and wetter grassland areas. [2]
The hairy-eared cerrado mouse breeds in the dry season in some areas and in the wet season in others. Litter sizes of two and three have been recorded. The home range averages 2,278 m2 (24,500 sq ft) and it is the second most abundant rodent in the cerrado after the hairy-tailed bolo mouse (Necromys lasiurus). [2]
This mouse has a wide range and is a common species. [1] The cerrado grassland in which it lives is increasingly being threatened by the expansion of industrial-scale farming, the burning of vegetation for charcoal and the development of dams to provide irrigation. [3] Although populations of the mouse may be in slight decline, the International Union for Conservation of Nature has assessed its conservation status as being of least concern because it believes the rate of population decline is not fast enough to justify placing it in a more threatened category.

The white-tailed rat also known as the white-tailed mouse, is the only member of the subfamily Mystromyinae in the family Nesomyidae. This species is sometimes placed in the subfamily Cricetinae due to similarities in appearance between the white-tailed rat and hamsters, but molecular phylogenetic studies have confirmed that the two groups are not closely related. The subfamily Mystromyinae is sometimes placed within the family Muridae along with all other subfamilies of muroids.
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 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.
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 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 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 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 longicaudatus, also known as the long-tailed colilargo or long-tailed pygmy rice rat, is a species of rodent in the genus Oligoryzomys of the family Cricetidae. It is found in the southern Andes of Chile and Argentina, with an outlying population in eastern Argentina. As a common species with a wide range and a stable population, the International Union for Conservation of Nature has rated this rodent as being of "least concern".
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 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 cerrado climbing mouse or long-tailed rhipidomys is an arboreal rodent species in the family Cricetidae from South America. It is found in primary or secondary forests of the cerrado and caatinga in central and eastern Brazil, and has also been seen in the Atlantic Forest. Its karyotype is 2n = 44, FN = 48-52. They are nocturnal animals and can be found in both tree canopies and on the ground.
Thalpomys is a genus of South American rodents in the tribe Akodontini of family Cricetidae. Two species are known, both found in the cerrado tropical savanna ecoregion of central Brazil. They are as follows:
The white-eared pocket mouse is a species of rodent in the family Heteromyidae. It is endemic to the San Bernardino Mountains and the Tehachapi Mountains of southern California in the United States. There are two subspecies of P. alticola in California, P. a. alticola and P. a. inexpectatus, both of which are considered species of special concern by the California Department of Fish and Wildlife.
