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.

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".

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.
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.

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.

It is endemic to south-eastern Brazil where it occurs in the Serra do Mar and Serra da Mantiqueira ranges in the states of Rio de Janeiro, São Paulo, and Minas Gerais. However, Araujo-Vieira and colleagues suggests that the Serra da Mantiqueira population could represent Sphaenorhynchus canga; the two species are similar.

It is endemic to the upper Amazon basin of southern Colombia, eastern Ecuador, and northeastern Peru; its range probably extends into adjacent western Brazil. The specific name nympha alludes to nymphs, beautiful wood- and marsh-dwelling goddesses in Greek mythology. Common name nympha Amazon treefrog has been proposed for it.
