The silky Oldfield mouse (Thomasomys bombycinus) is a species of rodent in the family Cricetidae. It is found only in Colombia.
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.
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 ashy-bellied Oldfield mouse is a species of rodent in the family Cricetidae. It is found in Colombia and Ecuador.
Daphne's Oldfield mouse is a species of rodent in the family Cricetidae. It is found in Bolivia and Peru.
The Peruvian Oldfield mouse is a species of rodent in the family Cricetidae. It is found only in Peru.
The woodland Oldfield mouse is a species of rodent in the family Cricetidae. It is found in Colombia and Venezuela.
The strong-tailed Oldfield mouse is a species of rodent in the family Cricetidae. It is found only in Peru.
Kalinowski's Oldfield mouse is a species of rodent in the family Cricetidae. It is found only in Peru.
Ladew's Oldfield mouse is a species of rodent in the family Cricetidae. It is found only in Bolivia.
The soft-furred Oldfield mouse is a species of rodent in the family Cricetidae. It is found in Colombia and Venezuela.
The distinguished Oldfield mouse is a species of rodent in the family Cricetidae. It is found only in Peru.
Thomas's Oldfield mouse is a species of rodent in the family Cricetidae.
Rosalinda's Oldfield mouse is a species of rodent in the family Cricetidae. It is found only in Peru.
The forest Oldfield mouse is a species of rodent in the family Cricetidae. It is found only in Ecuador.

The dressy Oldfield mouse is a species of rodent in the family Cricetidae. It is found only in Venezuela.
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.
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 Pichincha Oldfield mouse is a species of rodent in the family Cricetidae. It is present in the Cordillera Occidental of the Andes of Ecuador, where its habitats include shrubby páramo and montane forest. It is nocturnal and terrestrial. The specific and common names are references to the volcano Pichincha, which dominates the city of Quito and on whose slopes the species was discovered at an elevation of 3500 m. The mouse is threatened by conversion of its limited habitat to agricultural use. It has sometimes been considered to be conspecific with Aepeomys lugens.
