Charadrahyla nephila is a species of frog in the family Hylidae. It is endemic to Mexico and occurs in the Sierra de Juárez and Sierra Mixe in the northern Oaxacan highlands; there is also a questionable record from the Sierra de los Tuxtlas, Veracruz. Prior to its description, it was mixed with Hyla chaneque. The specific name nephila is derived from Greek nephos ("cloud") and philia ("fondness"), referring to the cloud forest habitat of this species. Common name Oaxacan cloud-forest treefrog has been coined for it.
Dendropsophus aperomeus is a species of frog in the family Hylidae. It is endemic to Peru and occurs on the Amazonian slopes of the Andes in northern and central Peru. Common name Balzapata treefrog has been coined for it.

It is endemic to southeastern Brazil and occurs in the coastal lowlands and the Serra do Mar in Espírito Santo, Minas Gerais, Rio de Janeiro, São Paulo, and eastern Paraná states. It is named in honor of Bertha Lutz, a Brazilian zoologist and feminist. Common name Bertha's treefrog has been coined for it.
Dendropsophus joannae is a species of frogs in the family Hylidae. It is known from the Pando Department, northern Bolivia, western Brazil, and Madre de Dios Region of southeastern Peru. It is similar to Dendropsophus leali but is smaller, has a shorter snout, more protuberant eyes, and more tuberculate dorsal skin. The specific name joannae honors Mrs. Jo Ann Oxley Foster, a BIOPAT patron supporting taxonomic research and nature conservation.
Dendropsophus stingi is a species of frogs in the family Hylidae. It is endemic to Colombia and occurs on the eastern slope of the Cordillera Oriental in the Boyacá Department. The species was named after celebrity musician Sting in recognition of his "commitment and efforts to save the rain forest". Despite this, common name Kaplan's Garagoa treefrog has been coined for it.
Dryaderces inframaculata is a species of frog in the family Hylidae. It is endemic to Brazil and known from between the Tapajós and Xingu Rivers in Pará. Until recently, it was only known from one specimen collected near Santarém, probably around 1876, by Henry Wickham. Common name Santarem treefrog has been coined for it.
Warren's tree frog is a species of frog in the family Hylidae found in Guyana and possibly Brazil and Venezuela. Its natural habitats are subtropical or tropical moist montane forests, rivers, freshwater marshes, and intermittent freshwater marshes.
Troschel's treefrog, also known as the blue-flanked treefrog or the convict treefrog, is a species of frog in the family Hylidae. It is found in most parts of the Amazon Basin including Suriname. Colombian, Guianan and Venezuelan records need confirmation.
Osteocephalus buckleyi, also known as Buckley's slender-legged treefrog, is a species of frog in the family Hylidae. It is found along the periphery of the Amazon Basin in Bolivia, Peru, Ecuador, Colombia, northeastern Brazil, Venezuela, Guyana, Suriname, and French Guiana, and also in the Orinoco Delta in Venezuela. It is probably a species complex. Some sources treat Osteocephalus vilmae from Ecuador and Peru as a valid species.
Osteocephalus cabrerai is a species of frog in the family Hylidae. It is found in the Amazon Basin in Brazil (Manaus), northeastern Peru, Ecuador, Colombia, Guyana, and French Guiana, possibly wider. Some earlier records refer to Osteocephalus buckleyi.
Osteocephalus deridens is a species of frog in the family Hylidae. It is found in the Napo and Pastaza River drainages in eastern Ecuador and in the Loreto Region, northern Peru. The specific name deridens is derived from Latin deridere, meaning "make fun of someone". This alludes to the males calling from the treetops that sound "as if they are laughing at the collectors' vain attempts to reach them". Common name funny slender-legged treefrog has been coined for this species.
Osteocephalus fuscifacies is a species of frog in the family Hylidae endemic to Ecuador. It is known from the Napo River drainage at intermediate elevations. The specific name fuscifacies is derived from Latin fuscus (=tan) and facies (=face), in reference to the uniform tan-colored loreal region and the lack of a light subocular spot. Common name Napo slender-legged treefrog has been coined for this species.
Dryaderces pearsoni is a species of frog in the family Hylidae. Broadly defined, it is found in Bolivia, Brazil, and Peru. However, the nominal taxon includes two species, and true Dryaderces pearsoni is only known with certainty from Bolivia. The specific name pearsoni honors Nathan E. Pearson, an American ichthyologist who made a "splendid collection of amphibians" during an expedition to Bolivia, including the holotype of this species. Common name Pearson's slender-legged treefrog has been coined for the species.
The Manaus slender-legged tree frog, also known as the giant broad-headed tree frog, is a species of frog in the family Hylidae found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, moist savanna, rivers, intermittent freshwater marshes, and canals and ditches. It is threatened by habitat loss. It is also reported to produce Bufotenin.
Scinax cruentomma is a species of frog in the family Hylidae. It is found in the upper Amazon Basin of southern Colombia, eastern Ecuador, northeastern and east-central Peru, and western Brazil; its presence is French Guiana is dispted. The specific name cruentomma is derived from the Greek cruentos meaning "bloody" and omma meaning "eye", referring to the red streak in the eye of this frog. This species is also known as the Manaus snouted treefrog.
Scinax ruber is a species of frog in the family Hylidae which is known in English as the red snouted treefrog or red-snouted treefrog, sometimes also Allen's snouted treefrog, the latter referring to the now-synonymized Scinax alleni. This widespread species is found in much of Amazonian and northern coastal South America and into Panama, as well as in some Caribbean islands as introduced populations. It is a complex containing several cryptic species.
Stefania evansi is a species of frog in the family Hemiphractidae. Stefania evansi is, along with other closely related frogs, known for its unusual reproductive mode where females carry the eggs and juveniles on their back. It is sometimes known under common names Groete Creek carrying frog, Groete Creek treefrog, or Evans' stefania. These names refer to its type locality, Groete Creek in the region Essequibo Islands-West Demerara, Guyana, where the holotype was collected by one Dr. R. Evans.
Dryaderces is a small genus of frogs in the family Hylidae. Their known distribution is disjunct, with one species found in the upper Amazon Basin and lower Andean slopes between central Peru and Amazonian Bolivia, and another one in Pará, Brazil. Its sister taxon is Osteocephalus. No phenotypic synapomorphies defining the genus are known.
Osteocephalus castaneicola is a species of frog in the family Hylidae. It is found in lowland Amazonia of northern Bolivia, adjacent southeastern Peru, and western Brazil. It breeds in water-filled fruit capsules of the Brazil nut, a characteristic also alluded to in its specific name castaneicola derived from the Latin castanea, the root of the vernacular name castaña for the Brazil nut, together with the Latin colō meaning "to inhabit".
