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.

Handleyomys fuscatus, also known as the dusky-footed Handley's mouse or dusky-footed montane mouse, is a species of rodent in the tribe Oryzomyini of family Cricetidae. It was previously placed in the genus Aepeomys, but it is closely similar to Handleyomys intectus, and accordingly both species were placed in the new genus Handleyomys in 2002. It is found only in Colombia.
Akodon affinis, also known as the Colombian grass mouse or Cordillera Occidental akodont, is a species of rodent in the family Cricetidae. It is found only in the Cordillera Occidental of Colombia.
Melanomys is a genus of rodent in the tribe Oryzomyini of family Cricetidae, which is distributed in northern South America and adjacent Central America. It contains three species, two of which—Melanomys robustulus and Melanomys zunigae—have limited distributions. The third, Melanomys caliginosus, is more widely distributed, but may be a species complex.
Melanomys robustulus, also known as the robust melanomys or robust dark rice rat, is a species of rodent in the genus Melanomys of family Cricetidae. It is found on the eastern slope of the Andes in Ecuador.
Melanomys zunigae, also known as Zuniga's melanomys or Zuniga's dark rice rat, is a species of rodent in the genus Melanomys of family Cricetidae. Known only from a small region of coastal Peru, it is listed as "critically endangered" by the IUCN and may even be extinct.
Neacomys pictus, also known as the painted neacomys or painted bristly mouse, is a species of rodent in the genus Neacomys of family Cricetidae. It is found only in Panama.
Nesoryzomys fernandinae, also known as the Fernandina nesoryzomys, Fernandina rice rat, or Fernandina Galápagos mouse, is a species of rodent in the genus Nesoryzomys of family Cricetidae. It is found only on Fernandina in the Galápagos Islands, which it shares with N. indefessus narboroughi. Its natural habitat is subtropical or tropical dry shrubland. The conservation status of this endemic species continues to be investigated.
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.

It is found in Belize, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. It was previously included in Oryzomys as Oryzomys alfaroi. Its natural habitats are subtropical and tropical lowland or montane dry forests at elevations ranging from sea level to 2500 m.
Oryzomys dimidiatus, also known as the Nicaraguan oryzomys, Thomas's rice rat, or Nicaraguan rice rat, is a rodent in the genus Oryzomys of the family Cricetidae. It is known from only three specimens, all collected in southeastern Nicaragua since 1904. Placed in Nectomys upon its discovery, it was later classified in its own subgenus of Oryzomys and finally recognized as closely related to other species now placed in Oryzomys, including the marsh rice rat and Oryzomys couesi, which occurs in the same region.
Euryoryzomys legatus, also known as the Tarija oryzomys or big-headed rice rat, is a species of rodent in the family Cricetidae. It now belongs to the genus Euryoryzomys, having previously been placed in Oryzomys. It is found in the eastern Andes of northwestern Argentina and southern Bolivia.
Aegialomys xanthaeolus, also known as the yellowish oryzomys or yellowish rice rat, is a species of rodent in the family Cricetidae. It belongs to the genus Aegialomys in tribe Oryzomyini, which was not recognized as distinct from Oryzomys until 2006. It is found in coastal Ecuador and Peru. Though it is currently the only formally recognized mainland species of Aegialomys, at least one other exists. The specific name is sometimes incorrectly spelled "xantheolus", without the second "a".
Sigmodontomys alfari, also known as the short-tailed sigmodontomys, Alfaro's rice water rat, Cana rice rat, or Allen's rice rat, is a species of rodent in the genus Sigmodontomys of family Cricetidae. It is found from Honduras through Nicaragua, Costa Rica, and Panama into South America, where it occurs from Venezuela through Colombia to Ecuador.
Sigmodontomys is a genus of rodent in the tribe Oryzomyini of family Cricetidae. It is related to Nectomys and Melanomys and used to be included in Nectomys. It includes two species, Sigmodontomys alfari and the much rarer Sigmodontomys aphrastus, but whether these are indeed each other's closest relatives is uncertain.
Zygodontomys brunneus, also known as the brown zygodont, brown cane mouse, or Colombian cane mouse, is a rodent species in the genus Zygodontomys of tribe Oryzomyini. It is found only in Colombia.
