Megastomatohyla is a genus of frogs in the family Hylidae. They are endemic to the cloud forests of central Veracruz and Oaxaca, Mexico. All are rare species with restricted distributions.

Common name large-mouthed treefrogs has been coined for this genus.

Sarcohyla celata, also known as the Oaxaca treefrog, is a species of frog in the family Hylidae. It is endemic to Mexico and only known from the Sierra de Juárez in northern Oaxaca. After having not been seen after 1984, it was feared that the species might be extinct.

Sarcohyla cembra, also known as the Southern Sierra Madre treefrog, is a species of frog in the family Hylidae. It is endemic to Mexico. Until recently, it was only known from two male specimens: one from its type locality on the Pacific slopes of the Sierra Madre del Sur mountains, Pochutla District, Oaxaca, and another one from Sierra de Yucuyacua south-east of Llano de Guadalupe, in north-west Oaxaca. The two locations are about 172 km (107 mi) apart. After having not been seen after 1993, it was feared that the species might be extinct.

Common name gloomy mountain stream frog has been coined for it.

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.
Triprion spatulatus is a species of frog in the family Hylidae. It is endemic to the Pacific lowlands of western Mexico between the Sinaloa and Oaxaca states. It is known by several common names: shovel-headed treefrog, Mexican shovel-headed treefrog, shovel-nosed tree frog, and shovelhead treefrog.
Pristimantis serendipitus is a species of frog in the family Craugastoridae. It is found in the Andes of northern Peru and adjacent southern Ecuador.

Common name Colan Mountains robber frog has been proposed for this species.
Chiasmocleis anatipes is a species of frog in the family Microhylidae. As currently known, it is endemic to northeastern Ecuador, but it is likely to occur also in adjacent parts of Peru and perhaps Colombia too.

Rheohyla is a genus of frogs in the family Hylidae. As currently recognized, it is monotypic, containing only Rheohyla miotympanum, also known as the small-eared hyla or small-eared treefrog. However, the nominal species likely is a complex of more than one species. It is endemic to eastern and central Mexico. The generic name refers to streams, the breeding habitat of this frog. The specific name is derived from Greek meion, a diminutive prefix, together with Greek tympanon (='drum') and refers to the small tympanum.
