Thomasomys is a genus of rodent in the family Cricetidae, [1] named after British zoologist Oldfield Thomas. Nuclear DNA sequence analysis has indicated that it is a sister taxon to Rhagomys . [2] It contains the following species:

Rodent Diverse order of mammals

Rodents are mammals of the order Rodentia, which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents ; they are found in vast numbers on all continents except Antarctica. They are the most diversified mammalian order and live in a variety of terrestrial habitats, including human-made environments.

Cricetidae family of mammals

The Cricetidae are a family of rodents in the large and complex superfamily Muroidea. It includes true hamsters, voles, lemmings, and New World rats and mice. At almost 608 species, it is the second-largest family of mammals, and has members throughout the Americas, Europe and Asia.

Michael Rogers Oldfield Thomas FRS FZS was a British zoologist.

The Apeco Oldfield mouse is a species of rodent in the family Cricetidae. It is known only from a single locality in north central Peru, which includes Rio Abiseo National Park, where it was found in cloud forest at an elevation of 3300 m. The species name comes from the acronym for the Asociacion Peruana para la Conservacion de la Naturaleza. It is among the largest members of the genus.

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 beady-eyed mouse is a species of rodent in the family Cricetidae. It is found only in Ecuador.

Sigmodontinae subfamily of mammals

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.

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 cinnamon-colored Oldfield mouse, also called the "cinnamon-colored Thomasomys", is a species of rodent in the family Cricetidae. It is present in the Cordillera Oriental of the Andes from north central Ecuador to southern Colombia, at elevations from 2,400 to 3,800 m. It has terrestrial habits, and has been found in cloud forest and mossy areas. It was formerly considered a subspecies of T. gracilis.

The wandering Oldfield mouse, also called the wandering thomasomys, is a species of rodent in the family Cricetidae. It has been found in both the Cordillera Oriental and Cordillera Occidental of the Andes in central and north central Ecuador, at elevations from 2400 to 3600 m. It has terrestrial habits, and has been found in cloud forest and areas of secondary vegetation. It was formerly considered a subspecies of T. cinereiventer.

The large-eared Oldfield mouse is a species of rodent in the family Cricetidae. It is known only from a single locality in the Andes in north central Peru, in montane forest at an elevation of 3300 m. It has terrestrial habits and is sympatric with T. apeco.

The Ashaninka Oldfield mouse is a species of rodent in the family Cricetidae. It is known only from a single locality in the Cordillera Oriental of the southern Peruvian Andes, in montane forest at an elevation of 3350 m. It has terrestrial habits.

<i>Thomasomys ucucha</i> Species of rodent from Ecuador

Thomasomys ucucha, also known as the ucucha thomasomys, is a rodent in the genus Thomasomys of the family Cricetidae. It is known only from high altitude forest and grassland habitats in the Cordillera Oriental of Ecuador. Seven other species of Thomasomys live in the same areas. First collected in 1903, T. ucucha was formally described as a new species in 2003 and most closely resembles T. hylophilus, which occurs further to the north. The species is listed as "vulnerable" in the IUCN Red List as a result of habitat destruction.

Rhagomys is a genus of South American rodents in the tribe Thomasomyini of the family Cricetidae. Two species separated by about 3100 km are known, from southeast Peru and Bolivia east of the Andes, and in the Atlantic Forest of southeast Brazil. An undetermined species of Rhagomys has also been reported from Mato Grosso in central Brazil. The species are as follows:
