Thomasomys auricularis commonly known as the red Andean thomasomys [3] is a species of rodent in the genus Thomasomys found in the western Andes of southwestern Ecuador.
Although described in 1923 by Harold Elmer Anthony, [4] T. auricularis was treated as synonym or subspecies of Thomasomys pyrrhonotus until they were identified as a separate species in 2003 and officially recognized in Mammal Species of the World (2005). [5] [6]
Thomasomys auricularis is medium in size for its genus, with a head-body length of 138 to 155 millimetres (5.4 to 6.1 in). It is characterized by its relatively long tail, moderately long hindfoot, large skull, and large, inflated auditory bullae. Initially it was compared to the similar looking T. aureus and T. pyrrhonotus but has a few distinguishing characteristics. The skull is smaller than T. aureus. The tail is longer than T. pyrrhonotus. The auditory bullae is larger T. aureus but comparatively smaller than T. pyrrhonotus. [6]
The species occurs in Polylepis forest within the páramo and montane forests primarily in region 6 and 7 of Ecuador, at medium and high elevations of 2,330 to 4,000 metres (7,640 to 13,120 ft). [6]
There is a distinct population in Cañar that potentially may be a subspecies or separate species. [6]
Thomasomys auricularis is listed as data deficient by the International Union for Conservation of Nature in due to a lack of general knowledge.
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.
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.
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.
Transandinomys bolivaris, also known as the long-whiskered rice rat, is a rodent in the family Cricetidae. It is found in humid forest from northeastern Honduras to western Ecuador, up to 1,800 m (5,900 ft) above sea level. Since it was first described in 1901 from Ecuador, six scientific names have been introduced for it, but their common identity was not documented until 1998 and the species has long been known under the name Oryzomys bombycinus, described from Panama in 1912. The name Oryzomys bolivaris was used before it was moved to the new genus Transandinomys with Transandinomys talamancae in 2006.
Nephelomys devius, also known as the Talamancan oryzomys, Boquete rice rat, Chiriqui rice rat, or montane rice rat, is a species of rodent in the genus Nephelomys of family Cricetidae. It is found in cloud forest in the highlands of Costa Rica and western Panama.
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.
Thomas's Oldfield mouse is a species of rodent in the family Cricetidae.
The Gobi jerboa is a species of rodent in the family Dipodidae. It is found in China and Mongolia. Its natural habitats are temperate grassland and temperate desert.
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.
Hudson's Oldfield mouse is a species of rodent in the family Cricetidae. It is known only from the Andes in southern Ecuador, where it has been found at an elevation of 3100 m. It was formerly considered a subspecies of T. gracilis. It is named after American zoologist Wilfred Hudson Osgood.
The Popayán Oldfield mouse, also called the "Popayán thomasomys", is a species of rodent in the family Cricetidae. It is present in the Andes of southwestern and central western Colombia, at elevations from 1800 to 3200 m. It has been found in páramo, montane forest, and secondary forest. It was formerly considered a subspecies of T. aureus. T. nicefori, presently considered a synonym, will likely be raised to the status of a separate species. The specific name comes from the Colombian city of Popayán.
The Cajamarca Oldfield mouse is a species of rodent in the family Cricetidae. It is present in the Andes of northwestern Peru, where its habitats include shrubby páramo, montane forest, and secondary forest. The rodent is nocturnal and may be partly arboreal. It was formerly considered a subspecies of T. aureus. The common name comes from the Peruvian city and region of Cajamarca.
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.
The Andean porcupine or Quichua porcupine is a species of rodent in the family Erethizontidae. It is found in the Andes of northern Ecuador and Colombia as well as in Panama. This porcupine is little known, but is probably arboreal, nocturnal and solitary like its relatives. The species is thought to be uncommon to rare and the population decreasing. It is threatened by deforestation, habitat fragmentation and agriculture.
Nephelomys moerex is a species of rodent in the genus Nephelomys of family Cricetidae. The type locality is at Mindo in western Ecuador, where it has been recorded together with three other rodents of the oryzomyine group, Sigmodontomys aphrastus, Mindomys hammondi, and Handleyomys alfaroi, as well as three opossums, Chironectes minimus and unidentified species of Didelphis and Marmosa. Mindo is a "tiny agricultural community" located at 0°02'S, 78°48'W and 1,264 metres (4,150 ft) above sea level. It was originally described by Oldfield Thomas as a subspecies of Oryzomys albigularis. It remained synonymized under this species until it was recognized as a separate species when the genus Nephelomys was established for Oryzomys albigularis and related species in 2006.
Nephelomys nimbosus is a species of rodent in the genus Nephelomys of family Cricetidae. Its type locality is at San Antonio on the northeastern slope of the Tungurahua in the Andes of Ecuador, at an altitude of about 6,700 feet (2,000 m). The type series included five individuals.
