Oecomys jamari, also known as the Jamari arboreal rice rat, is a newly described species of rice rat endemic to Brazil. [1] [2]
The rodent subfamily Sigmodontinae includes New World rats and mice, with at least 376 species. Many authorities include the Neotominae and Tylomyinae as part of a larger definition of Sigmodontinae. When those genera are included, the species count numbers at least 508. Their distribution includes much of the New World, but the genera are predominantly South American, such as brucies. They invaded South America from Central America as part of the Great American Interchange near the end of the Miocene, about 5 million years ago. Sigmodontines proceeded to diversify explosively in the formerly isolated continent. They inhabit many of the same ecological niches that the Murinae occupy in the Old World.
Oecomys auyantepui, also known as the Guianan oecomys and north Amazonian arboreal rice rat, is a species of rodent in the genus Oecomys from South America. It is found in Guyana, Suriname, French Guiana, and nearby regions of Venezuela and Brazil. It is an arboreal rodent known from the understory of primary rainforest, found at altitudes from sea level to 1100 m.
Oecomys bicolor, also known as the white-bellied oecomys or bicolored arboreal rice rat, is a species of rodent in the genus Oecomys of family Cricetidae. It has a wide distribution in the Amazon biome, occurring in northwestern Brazil, northern Bolivia, eastern Peru, eastern Ecuador, eastern Colombia, much of Venezuela, Guyana, Suriname, and French Guiana, and extends into eastern Panama, but it may contain more than one species.
Oecomys cleberi, also known as Cleber's oecomys or Cleber's arboreal rice rat, is a species of rodent in the genus Oecomys of family Cricetidae. Known only from the Federal District in Brazil, its taxonomic status relative to O. concolor and O. paricola is unresolved.
Oecomys concolor, also known as the unicolored oecomys, unicolored rice rat, or unicolored arboreal rice rat, is a species of rodent in the genus Oecomys of family Cricetidae. It is found in tropical rainforest in the Amazon biome, but its range is poorly documented; it has been recorded in northwestern Brazil, southeastern Colombia, and southern Venezuela.
The mamore arboreal rice rat,, also known as the Mamore oecomys is an arboreal species of rodent in the genus Oecomys of family Cricetidae. Its distribution extends over much of Bolivia and into nearby Brazil and Paraguay. Although Oecomys has been recorded from Argentina, it is uncertain whether those records represent O. mamorae. It is found in a variety of habitats at elevations from 200 to 2100 m, where it feeds on fruit and green seeds.
Oecomys paricola, also known as the Brazilian oecomys, Brazilian arboreal rice rat, or South Amazonian arboreal rice rat, is a species of rodent in the genus Oecomys of family Cricetidae. It is found in central Brazil south of the Amazon, where it lives in lowland tropical rainforest.
Oecomys rex, also known as the regal oecomys or king arboreal rice rat, is a species of rodent in the genus Oecomys of family Cricetidae. It is found in Guyana, Suriname, French Guiana, and nearby parts of Venezuela and Brazil.
Oecomys roberti, also known as Robert's oecomys or Robert's arboreal rice rat, is a rodent species from South America in the genus Oecomys. It has a broad distribution in the Amazon biome, being found in Bolivia, Brazil, French Guiana, Guyana, Peru, Suriname and Venezuela.
Oecomys trinitatis, also known as the long-furred oecomys, long-furred rice rat, Trinidad arboreal rice rat, or big arboreal rice rat, is a species of rodent in the genus Oecomys of family Cricetidae. As currently constituted, it has a wide distribution in Central America and South America, being found in southern Costa Rica, Panama, Colombia, Venezuela, Trinidad and Tobago, Guyana, Suriname, French Guiana, much of Brazil, eastern Ecuador, and eastern Peru.
Oecomys is a genus of rodent within the tribe Oryzomyini of family Cricetidae. It contains about 17 species, which live in trees and are distributed across forested parts of South America, extending into Panama and Trinidad.
Oecomys flavicans, also known as the tawny oecomys or yellow arboreal rice rat, is a species of rodent in the genus Oecomys of family Cricetidae. It is found in the mountains of northwestern Venezuela and nearby Colombia.
Oecomys phaeotis, also known as the dusky arboreal rice rat or dusky oecomys, is a species of rodent in the genus Oecomys of family Cricetidae. It is found on the eastern slopes of the Andes of Peru, at 1500 to 2000 m altitude.
Oecomys rutilus, also known as the reddish oecomys or red arboreal rice rat, is a species of rodent in the genus Oecomys of family Cricetidae. It is found in Guyana, Suriname, French Guiana, and nearby regions of Brazil and Venezuela.
Oecomys speciosus, also known as the savannah oecomys, arboreal rice rat, or Venezuelan arboreal rice rat, is a species of rodent in the genus Oecomys of family Cricetidae. It ranges over northeastern Colombia and much of Venezuela, including the island of Trinidad. This rodent lives in tropical rainforest and tropical dry forest, including secondary forest and gallery forest, as well as in savanna habitat.
Oecomys superans, also known as the large oecomys or foothill arboreal rice rat, is a species of rodent in the genus Oecomys of family Cricetidae. It is found along the eastern slope of the Andes in southern Colombia, Ecuador, and Peru and east into the Amazon basin, including parts of Brazil. Its distribution is poorly known, and it may also occur further south, into Bolivia.
Oecomys sydandersoni is an arboreal species of rodent in the genus Oecomys. It lives in forest patches in a small area in eastern Bolivia. It is a medium-sized species, weighing about 45 g (1.6 oz), with mostly grayish and brownish fur and short and broad hindfeet with well-developed pads.
