WBangs's mountain squirrel is a poorly known species of tree squirrel, that only lives in Costa Rica and Panama. It can be found in mountain rain forests at an altitude between 1,900 and 2,600 metres, and lives mainly in the tree tops, but sometimes on the forest floor as well. One of its habitats is at the summit of the Poás Volcano in Costa Rica, in a Clusia forest that is almost inaccessible to humans.

The main portion of its range is from Chiapas and the Yucatan Peninsula, through Central America, to northwestern Ecuador, Colombia and far western Venezuela. A highly disjunct population is found in southeastern Peru, far southwestern Brazil, Bolivia, western Paraguay and far northwestern Argentina. The disjunct population has been treated as a separate species, the brown agouti, but a major review of the geographic variation is necessary. The Central American agouti has also been introduced to Cuba and the Cayman Islands.
WThe Central American dwarf squirrel, also known as Alfaro's pygmy squirrel,(Microsciurus alfari) is a small tree squirrel in the genus Microsciurus and tribe Sciurini found in Colombia, Costa Rica, Nicaragua, and Panama. No species of squirrel within this genus are endangered, but they are rarely seen because they are shy and live hidden lives. This suggests that their population numbers may be larger than documented.

WThe lesser capybara is a large semiaquatic rodent of the family Caviidae found in eastern Panama, northwestern Colombia, and western Venezuela. The lesser capybara was described as a species in 1912, but later demoted to a subspecies of the capybara. Following studies of anatonomy and genetics in the mid-1980s, it was recommended that it again should be recognized as a separate species, and this gained more widespread recognition in 1991, although some continue to consider it a subspecies.

WOligoryzomys fulvescens, also known as the fulvous colilargo, fulvous pygmy rice rat, or northern pygmy rice rat, is a species of rodent in the genus Oligoryzomys of family Cricetidae. It is found from southern Mexico through Central America into South America, where it occurs south into Peru and Brazil, and includes numerous synonyms, including the type species of the genus, Oryzomys navus Bangs, 1899. The taxonomy of this species is unresolved, and it may be found to contain more than one species. Its karyotype has 2n = 54-60 and FNa = 68–74.
WOryzomys couesi, also known as Coues' rice rat, is a semiaquatic rodent in the family Cricetidae occurring from southernmost Texas through Mexico and Central America into northwestern Colombia. It is usually found in wet habitats, such as marshes, but also lives in drier forests and shrublands. Weighing about 43 to 82 g, O. couesi is a medium-sized to large rat. The coarse fur is buff to reddish above and white to buff below. The hindfeet show some specializations for life in the water, such as reduced ungual tufts of hair around the digits. It has 56 chromosomes. There is much geographic variation in size, proportions, color, and skull features. Oryzomys couesi is active during the night and builds nests of vegetation that are suspended among reeds about 1 m (3.3 ft) above the ground. It is an excellent swimmer and dives well, but can also climb in vegetation. An omnivore, it eats both plant and animal food, including seeds and insects. It breeds throughout the year; females give birth to about four young after a pregnancy of 21 to 28 days. The species may be infected by several different parasites and by two hantaviruses.
WOryzomys 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.

WRothschild's porcupine, Coendou rothschildi, is a species of rodent in the family Erethizontidae. It is usually considered endemic to Panama. A population in western Ecuador belongs either to this species or to Coendou bicolor. Because of the confusion over its taxonomic status and because its ecology is little known, the IUCN has listed its conservation status as "data deficient".
WThe Ruatan Island agouti, also called the Roatán Island agouti, is a species of agouti in the family Dasyproctidae. It is endemic to the island of Roatán, off the north coast of Honduras, and is threatened by habitat loss and hunting. There are no known subspecies.
WThe rufous soft-furred spiny-rat, known as ratón espinoso meaning "spiny" or "thorny" rat in Spanish, is a species of rodent in the family Echimyidae. It is found in Colombia, Ecuador, and Panama. In November 2015, it was spotted for the first time in Osa, Costa Rica by the Costa Rican researcher Jim Córdoba-Alfaro.
WThe southern cotton rat is a rodent species in the family Cricetidae. It is found from southern Chiapas in Mexico through Central America, except for Belize, and as far east as northern Colombia and Venezuela. It lives in tropical rainforest, dry forest and savanna, as well as in cultivated areas. The species is terrestrial and primarily diurnal. It was long thought to be a subspecies of S. hispidus. However, recent taxonomic revisions, based on mitochondrial DNA sequence data, have split the extensive former species range into three separate species. Carroll et al. (2004) indicate that the southern edge of the S. hispidus distribution is likely near the Rio Grande where it meets the northern distribution of S. toltecus. The range of S. toltecus extends from northern Mexico south into Chiapas where it occurs in sympatry with S. hirsutus . Rats from this species group have been used as laboratory animals.

WTransandinomys bolivaris, also known as the long-whiskered rice rat, is a rodent in the genus Transandinomys. 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.
WTransandinomys talamancae is a rodent in the genus Transandinomys that occurs from Costa Rica to southwestern Ecuador and northern Venezuela. Its habitat consists of lowland forests up to 1,500 m (5,000 ft) above sea level. With a body mass of 38 to 74 g, it is a medium-sized rice rat. The fur is soft and is reddish to brownish on the upperparts and white to buff on the underparts. The tail is dark brown above and lighter below and the ears and feet are long. The vibrissae (whiskers) are very long. In the skull, the rostrum is long and the braincase is low. The number of chromosomes varies from 34 to 54.
