The glass frogs belong to the amphibian family Centrolenidae, native to the Central American Rainforests. The general background coloration of most glass frogs is primarily lime green, the abdominal skin of some members of this family is transparent and translucent, giving the glass frog its common name. The internal viscera, including the heart, liver, and gastrointestinal tract, are visible through the skin. When active their blood makes them visible; when sleeping most of the blood is concealed in the liver, hiding them. Glass frogs are arboreal, living mainly in trees, feeding on small insects and only coming out for mating season. Their transparency conceals them very effectively when sleeping on a green leaf, as they habitually do. However, climate change and habitat fragmentation has been threatening the survival rates of the family.
The golden coquí is a rare, possibly extinct species of frog endemic to Puerto Rico.
Adelophryne is a genus of frogs in the family Eleutherodactylidae. They are native to northern South America east of the Andes, known roughly from the area corresponding to the Guiana Shield, as well as to the coastal area of Bahia, Brazil. Whether the genus is truly distinct from Phyzelaphryne remains uncertain. Common name shield frogs has been proposed for this genus, although the stem flea frog is used for some species.
Craugastor chrysozetetes is a possibly extinct species of frog in the family Craugastoridae. It is endemic to Honduras where it is only known from near its type locality on the Cerro Búfalo, Cordillera de Nombre de Dios, at the edge of the Pico Bonito National Park. Common name McCranie's robber frog has been coined for this species. However, James McCranie himself has argued that this name "should be rejected in favor of a name associated with the type locality instead of a name tied to one of the three authors who named this species".
Yunganastes ashkapara is a species of frog in the family Strabomantidae. It is endemic to Bolivia and is known from the vicinity of its type locality in the Chapare Province and from Abra de la Cruz in the Manuel María Caballero Province.

Pristimantis repens, known commonly as the Galeras robber frog, is a species of frog in the family Strabomantidae. It is endemic to the Colombian Massif in the Nariño Department, Colombia. The specific name repens is Latin for creeping or crawling, inferred to be its mode of locomotion based on its short limbs.
Pristimantis simoterus is a species of frog in the family Strabomantidae. It is endemic to Colombia and known from the Cordillera Central in the Caldas, Risaralda, Quindío, and Tolima Departments. Common name Albania robber frog has been coined for it. The specific name simoterus is derived from Greek simos meaning "snub-nosed", in reference to the short snout of this species.
Noblella lochites, also known as Ecuador leaf frog, is a species of frog in the family Strabomantidae. It is found on the Amazonian slopes of the Andes and Cordillera del Cóndor and the Cordillera de Cutucú in Ecuador and Peru; the Peruvian record has been disputed, although it is nevertheless expected that the species occurs in Peru.
Noblella myrmecoides is a species of frog in the family Strabomantidae. It is found in the upper Amazon Basin of southeastern Colombia, eastern Ecuador, eastern Peru, Bolivia, and western Brazil (Amazonas). Common name Loreto leaf frog has been coined for this species.
Engystomops pustulatus is a species of frog in the family Leptodactylidae. It is known with certainty from western Ecuador, whereas the status of Peruvian records is ambiguous as they may refer to an undescribed species or possibly Engystomops puyango. Nevertheless, given that E. pustulatus is now known from Huaquillas in southern Ecuador, near the Peruvian border, it is likely to be found in Peru too.
Yunganastes is a small genus of frogs in the family Strabomantidae found in southern Peru and central to northern Bolivia. They were formerly placed in the genus Eleutherodactylus as the "Eleutherodactylus fraudator group", subsequently moved to Pristimantis, before becoming recognized as a separate subgenus, and finally, a genus. Its sister taxon is the genus Pristimantis. Yunganastes are endemic to the cloud forests and humid montane forests of the Cordillera Oriental of the Andes in Bolivia and southern Peru.
