Hylidae

Hylidae is a wide-ranging family of frogs commonly referred to as "tree frogs and their allies". However, the hylids include a diversity of frog species, many of which do not live in trees, but are terrestrial or semiaquatic.

Trachycephalus is a genus of frogs, commonly known as the casque-headed tree frogs, in the family Hylidae. They are found in Mexico, Central America, and South America. In a recent revision, the seven species of the genus Phrynohyas were included in this genus, and Phrynohyas is now considered a synonym of Trachycephalus. These frogs inhabit the canopies of tropical rainforests, where they breed in tree cavities, and rarely, if ever, descend to the ground.

Tepuihyla, commonly known as Amazon tree frogs or Tepui tree frogs, is a genus of frogs in the family Hylidae found in mountains of eastern and south-eastern Venezuela and Guyana, and likely in adjacent Brazil. Tepuihyla derives from the words tepui; table-top mountains characteristic of the Guiana Highlands, and Hyla, a wastebasket taxon that used to contain hundreds of species.

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.

Itapotihyla is a genus of frogs in the family Hylidae. It is monotypic, being represented by the single species Itapotihyla langsdorffii, commonly known as the ocellated treefrog. It is found in the Atlantic Forest biome of Brazil, with an isolated population in eastern Paraguay and adjacent Brazil and northeastern Argentina.
