The saddleback toads (Brachycephalus) are a genus of tiny toads and frogs in the family Brachycephalidae in the order Anura, ranging from south Bahia to Santa Catarina in southeastern Brazil. The genus includes two main groups, the often brightly coloured pumpkin toadlets, and the overall brown and more frog-like flea frogs, which once were placed in their own genus Psyllophryne. Some pumpkin toadlets are toxic and their often bright colours are considered aposematic. At about 1 cm (0.4 in) or less in snout–to–vent length, the flea frogs are some of the smallest frogs in the world.
The Brachycephalidae are a family of frogs confined to eastern and southern Brazil and northern Argentina. The family is composed of two externally quite different genera: the tiny, often colourful and plump saddleback toads (Brachycephalus) from Brazil, and the larger, slimmer and more drab genus Ischnocnema from both Brazil and Argentina. The family is mainly defined by molecular characteristics, and are linked by few anatomical features. It was erected from two genera of the previously large family Eleutherodactylidae, which is now split into four families.
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.
Barycholos, common name Chimbo frogs, is a genus of small frogs in the family Strabomantidae found in south-eastern Brazil and tropical lowland Ecuador. The name Barycholos, from the Greek βαρύχολος ("savage"), is in honor of herpetologist Jay M. Savage.
Mount Duida frogs (Dischidodactylus) form a genus of brachycephaloid frogs endemic to the tepuis of southern Venezuela. The scientific name is derived from the Greek dischidos, meaning divided, and dactylos, meaning finger or toe, in reference to the divided ungual flap.
Euparkerella, sometimes known as Guanabara frogs, is a genus of frogs in the family Strabomantidae. They are endemic to the Atlantic coastal forests in the south-eastern Brazilian states of Espírito Santo and Rio de Janeiro. The name Euparkerella honours H. W. Parker, a herpetologist who named the type species, with the Greek prefix eu meaning true and suffix ella, a diminutive form.
Holoaden, the highland frogs, is a small genus of frogs in the family Strabomantidae. The species are endemic to south-eastern Brazil.
Ischnocnema is a genus of frogs from eastern Brazil and north-eastern Argentina. They comprise the former Eleutherodactylus from this region, but they are closer to Brachycephalus than the "true" Eleutherodactylus. Consequently, they are now placed in their own genus Ischnocnema in the family Brachycephalidae.
Craugastor laticeps is a species of frog in the family Craugastoridae. It is found in Belize, Guatemala, Honduras, and southern Mexico.
Craugastor phasma is a species of frog in the family Craugastoridae. It is endemic to southeastern Costa Rica and only known from its type locality in the Las Tablas protected area in the Puntarenas Province, near the Panamanian border. Only a single individual—the holotype collected in 1992—has ever been observed. It is unusual in its ghost-like, gray-white coloration, and it was initially thought that the specimen was an albino form of some other species. However, the specimen is also morphologically distinct, although some uncertainty regarding the validity of this species remains.
Diasporus hylaeformis, also known as the Pico Blanco robber frog or the montane dink frog, is a species of frog in the family Eleutherodactylidae. It is found in humid mountain areas in Costa Rica and Panama. Its natural habitats are dense montane forest and tropical rainforest. It is an abundant, nocturnal species found in low vegetation.
Niceforonia columbiana is a species of frog in the family Strabomantidae, sometimes known as the Colombian Andes frog. It is endemic to Colombia. It is only known from the holotype, which is now lost. The type locality, "Monte Redondo, Buenavista" on the Cordillera Oriental, is in either Cundinamarca or Meta Department, and is considered questionable by some. It might be a synonym of Leptodactylus hylaedactylus.
Niceforonia nana is a species of frog in the family Strabomantidae. It is endemic to the Cordillera Oriental, Colombia, and found at 3,000–3,850 m (9,840–12,630 ft) asl.
Bryophryne is a genus of frogs in the family Strabomantidae. These frogs are endemic to south-eastern Peru in the Cusco Region, with an undescribed species from the Puno Region. Their range is separated from that of Phrynopus by the Apurímac River valley.
Craugastoridae, commonly known as fleshbelly frogs, is a family of New World direct-developing frogs. As delineated here, following the Amphibian Species of the World, it contains 129 species. They are found from the southern United States southwards to Central and South America.
Strabomantis is a genus of frogs in the family Strabomantidae. At times these frogs have been included in the large genus Eleutherodactylus. They are distributed from Costa Rica southwards to northern South America.
Niceforonia is a genus of frogs in the family Strabomantidae found in northern South America. The name refers to Nicéforo María, Colombian herpetologist.
Noblella is a genus of frogs in the family Strabomantidae. They are found on the eastern slopes of the Andes and in the Amazon Basin in Colombia, Ecuador, Peru, Bolivia, and western Brazil. The name refers to Gladwyn K. Noble, who described the first species.
Ceuthomantis is a small genus of craugastorid frogs, also treated as comprising their own monogeneric family Ceuthomantidae. They are found in the southern and eastern parts of the Guiana Highlands in Venezuela, Guyana, and Brazil. The generic name is derived from the Greek noun mantis, which means treefrog, and adjective keuthos, which means hidden, in allusion to the hidden existence of this genus in the tepuis of the Guiana Shield.
Eleutherodactylus paralius, commonly known as the coastal red-rumped frog, is a species of frog in the family Eleutherodactylidae. It is endemic to the Dominican Republic, specifically the southeastern region.
