The Amazon weasel, also known as the tropical weasel, is a species of weasel native to South America. It was first identified from a museum specimen mislabelled as coming from Africa, hence the scientific name.
The brown-eared woolly opossum, also known as the western woolly opossum, is an opossum from South America. It was first described by German naturalist Ignaz von Olfers in 1818. The opossum is characterized by a brown to reddish brown coat and similarly colored limbs, yellow to orange underbelly, hairless, brown ears with a hint of pink, and a tail furred on the back for up to half of its length. The brown-eared woolly opossum is nocturnal, solitary and omnivorous. The IUCN lists it as least concern.
Pagaibamba Protection Forest is a protected natural area in the region of Cajamarca, Peru. The area was declared a protection forest in order to preserve the water supply of surrounding towns, preserve the water cycle of the area, protect road infrastructure and protection of soils by preventing erosion.
The hairy-legged myotis is a species of mouse-eared bat. It is found from southern Tamaulipas in Mexico, through much of Central America and across northern South America as far east as Trinidad. Further south, it is found along the foothills of the Andes as far south as northern Argentina.
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.
Nephelomys auriventer, also known as the golden-bellied oryzomys or Ecuadorian rice rat, is a species of rodent in the genus Nephelomys of family Cricetidae. Oldfield Thomas originally described it, in 1899, as a species of Oryzomys, Oryzomys auriventer, and considered it most similar to Oryzomys aureus. In 1926, a subspecies was described from an Ecuadorian locality, Oryzomys auriventer nimbosus, and it was suggested that O. auriventer was closely related to O. albigularis. This proposal was formalized in 1961 by including O. auriventer within the species O. albigularis, but by 1976 O. auriventer was recognized again as a separate species. In 2006, Oryzomys albigularis and related species, including O. auriventer, were transferred to the new genus Nephelomys. Simultaneously, the former subspecies nimbosus was recognized as a separate species, Nephelomys nimbosus.
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.
Thomasomys is a genus of rodent in the family Cricetidae, named after British zoologist Oldfield Thomas. Nuclear DNA sequence analysis has indicated that it is a sister taxon to Rhagomys. It contains the following species:
The ash-colored Oldfield mouse is a species of rodent in the genus Thomasomys. It is found in montane forests of the Department of Cajamarca in northern Peru, at elevations of 1,524 to 3,818 metres. Until 2023, it was thought to be more widely distributed, ranging into southern Ecuador, but these populations are now identified as three separate, closely related species, T. lojapiuranus, T. pagaibambensis, and T. shallqukucha.
The scarlet-shouldered parrotlet, also known as the red-winged parrotlet or Huet's parrotlet, is a species of bird in subfamily Arinae of the family Psittacidae, the African and New World parrots. It is found in Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, and Venezuela, possibly in Suriname, and as a vagrant to Trinidad and Tobago.
The northern caenolestid, also known as the blackish shrew opossum, is a shrew opossum found in Colombia and Ecuador. It is listed as Vulnerable by the IUCN.
The northern viscacha is a species of viscacha, a rodent in the family Chinchillidae. It is known from Peru and Chile, at elevations from 300 to 5000 m, and may also be present in Bolivia.
The Guayaquil squirrel is a tree squirrel endemic to Ecuador and Peru. It is a robust squirrel with a head-and-body length of 18 to 32 cm and a similar length tail. The colour is variable; in Peru, a pale morph is more common, while in Ecuador, most individuals have darker grey fur on the forequarters, dull orange hindquarters. A melanistic morph is sometimes seen. It lives largely in trees and is diurnal, feeding on seeds, flowers, and other plant material, fungi and some insects. These squirrels are also found in urban areas, living in close proximity to humans, and may be vectors for leptospirosis and Chagas disease. This squirrel faces no particular threats, has a wide range and is relatively common, and the International Union for Conservation of Nature has rated it as being of "least concern".
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.
Oreocallis is a South American plant genus in the family Proteaceae. There is only one species, Oreocallis grandiflora, which is native to mountainous regions in Peru and Ecuador.
Lagidium ahuacaense is a rodent in the mountain viscacha genus (Lagidium) that occurs in southern Ecuador. First observed in 2005 and formally described in 2009, it occurs more than 500 km (310 mi) north of the nearest previously known population of mountain viscachas in central Peru. Only a single population is known, found on rocky habitats on Cerro El Ahuaca, an isolated granite mountain in southern Ecuador, and as few as several dozen individuals remain. The species is threatened by fires and grazing cattle, and the discoverers recommended its conservation status be assessed as critically endangered.
The Matapalo broad-nosed bat is a species of leaf-nosed bat described in 2005. It is found in South America.
Thomasomys shallqukucha is a species of rodent in the genus Thomasomys known from the Andes of northern Peru. It consists of populations that were identified as Thomasomys cinereus until they were identified as a new species in 2023.
Thomasomys pagaibambensis is a species of rodent in the genus Thomasomys known from the Andes of northern Peru. It consists of populations that were identified as Thomasomys cinereus until they were identified as a new species in 2023.
