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.
Melanophryniscus is a genus of toads in the family Bufonidae. They are found in northern half of Argentina, southern Bolivia, southern Brazil, Paraguay, and Uruguay. Common name South American redbelly toads has been coined for them.
Osteopilus is a genus of frogs in the family Hylidae. These species have a bony co-ossification on the skull resulting in a casque, hence its name ‘bone-cap’, from osteo- (‘bone’) and the Greek pilos. Color varies between uniform brown, brown-gray, or olive with darker markings or marbled with greens, grays or brown, making a distinct pattern. The finger disks are round; the fingers with a reduced webbing; eyes and tympanum are large. Their natural range includes the Greater Antilles and the Bahamas, but O. septentrionalis has also been introduced to the Lesser Antilles, Hawaii and Florida (USA).
Scinax is a genus of frogs in the family Hylidae found in eastern and southern Mexico to Argentina and Uruguay, Trinidad and Tobago, and Saint Lucia. These are small to moderate-sized tree frogs, drably colored. Duellman and Wiens resurrected this genus in 1992. The name originates from the Greek word skinos, meaning quick or nimble.
Sphaenorhynchus is a genus of frogs in the family Hylidae. They are also known as lime treefrogs or hatchet-faced treefrogs. They are found in the Amazon and Orinoco River basins of South America, the Guianas, Trinidad, and southern and eastern Brazil. The majority of the species are associated with the Atlantic Forest domain in Brazil.
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. A tepui is a table-top mountain characteristic of the Guiana Highlands.
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 seldom, if ever, descend to the ground.
Triprion is a genus of frogs in the family Hylidae found in the Pacific lowlands of Mexico, the Yucatán Peninsula, and Guatemala. These frogs hide in tree-holes and plug the entrance with their strange-looking, bony heads.
Pseudacris is a genus of frogs in the family Hylidae found in North America ranging from the Pacific coastline to the Atlantic.
Spikethumb frogs are a genus (Plectrohyla) of frogs in the family Hylidae found in Central America from southern Mexico through Guatemala and northern El Salvador to central and northern Honduras. A major revision of the Hylidae moved an additional 21 species to this genus from the genus Hyla. The additional species moved to Plectrohyla were identified as the Hyla bistincta group, also called the Plectrohyla bistincta group; a separate group from the initial Plectrohyla guatemalensis group. This phylogenetic classification was later revised by moving the Plectrohyla bistincta group from the genus Plectrohyla into a new genus called Sarcohyla. Meanwhile, the guatemalensis group remained in Plectrohyla. They are called spikethumb because of the spike on their thumbs, which is called a prepollex. The genus name comes from the Greek word plēktron ("spur") and hyla.
Phyllodytes is a genus of frogs in the family Hylidae. It is endemic to eastern Brazil.
Osteocephalus is a genus of frogs, the slender-legged tree frogs, in the family Hylidae found in the Guianas, the Amazon Basin, Venezuela, Colombia, southeastern Brazil, and north-eastern Argentina. Males are warty, while females are smooth.
Dendropsophus is a genus of frogs in the family Hylidae. They are distributed in Central and South America, from southern Mexico to northern Argentina and Uruguay. They are sometimes known under the common name Fitzinger neotropical treefrogs or yellow treefrogs
Bokermann's casque-headed frog is a species of frog in the family Hylidae. It is endemic to Brazil, known only from Juréia-Itatins Ecological Station, another location 10 km away and Rio Verde. Its natural habitats are subtropical or tropical moist lowland forests.
Bruno's casque-headed frog is a species of frog in the family Hylidae. Endemic to Brazil, its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist shrubland, and intermittent freshwater marshes. It is threatened by habitat loss. The specific name brunoi was in honour of Dr Bruno Lobo, Professor and Director of the National Museum of Brazil (1915-1923).
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.
Hylinae is a large subfamily of "tree frogs", family Hylidae.
Nyctimantis arapapa, also known as Bahia's broad-snout casque-headed tree frog, is a species of frog endemic to the Atlantic Rainforest of southern Bahia, Brazil. The frogs of the genus Nyctimantis are distinguished by a bony plate on top of their heads, referred to as "casque-headed". Casque-headed frogs are characterized by their phragmotic behavior. N. arapapa is further characterized by the long bill-shaped "snout" they possess, similar to that of Triprion petasatus, a head longer than it is wide, and their small size. This species, and all species of Nyctimantis, use their unique head shape to seal off the leaves of bromeliads, the plant they inhabit solely. This has two known purposes: warding off predators from the frog as well as their young, and trapping moisture.
Pithecopus is a genus of frogs in the subfamily Phyllomedusinae. Species of the genus Pithecopus are found in tropical South America east of the Andes, from southern Venezuela to northern Argentina. Resurrected from the synonymy of Phyllomedusa in 2016, it corresponds to the former Phyllomedusa hypochondrialis group. Its sister group is Callimedusa.
Nyctimantis pomba is a frog in the family Hylidae, endemic to Brazil. Scientists have seen it in exactly one place, 233 meters above sea level in the rainforest in Minas Gerais.
