The Microhylidae, commonly known as narrow-mouthed frogs, are a geographically widespread family of frogs. The 683 species are in 57 genera and 11 subfamilies.
The glass frogs belong to the amphibian family Centrolenidae. While the general background coloration of most glass frogs is primarily lime green, the abdominal skin of some members of this family is transparent and translucent, giving the glass frog its common name. The internal viscera, including the heart, liver, and gastrointestinal tract, are visible through the skin. When active their blood makes them visible; when sleeping most of the blood is concealed in the liver, hiding them. Glass frogs are arboreal, living mainly in trees, and only come out for mating season. Their transparency conceals them very effectively when sleeping on a green leaf, as they habitually do.
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.
Pseudis is a genus of South American frogs in the family Hylidae. They are often common and frequently heard, but easily overlooked because of their camouflage and lifestyle, living in lakes, ponds, marshes and similar waters with extensive aquatic vegetation, often sitting at the surface among plants or on floating plants, but rapidly diving if disturbed. Whereas the adults are medium-sized frogs, their tadpoles are large; in some species the world's longest.
Physalaemus is a large genus of leptodactylid frogs. These frogs, sometimes known as dwarf frogs or foam frogs, are found in South America. It is very similar to Leptodactylus, a close relative, and indeed the recently described Leptodactylus lauramiriamae is in some aspects intermediate between them.
Leptodactylus is a genus of leptodactylid frogs. It includes the species commonly called ditch frogs or white-lipped frogs. It is very similar to Physalaemus, a close relative, and indeed the 2005 described Leptodactylus lauramiriamae is in some aspects intermediate between them. The name means ‘slender finger’, from leptos and the Greek daktylos.
Cophylinae is a subfamily of microhylid frogs endemic to Madagascar. It has over 100 species in eight genera. Members of this subfamily range from minute to fairly large, and they are highly ecologically diverse. DNA barcode research has revealed a significant taxonomic gap in this subfamily, and an estimated 70+ candidate species were identified. Many of these have subsequently been described, as well as numerous new discoveries.
Stereocyclops is a small genus of microhylid frogs. It is endemic to the Atlantic forest of eastern Brazil. Molecular phylogeny suggests that it is sister taxon to the clade containing Dasypops and Myersiella.
Boana is a genus of frogs in the family Hylidae. They are commonly known as gladiator frogs, gladiator treefrogs or Wagler Neotropical treefrogs. These frogs are distributed in the tropical Central and South America from Nicaragua to Argentina, as well as in the Caribbean.
Uperodon taprobanicus, also known as the Sri Lankan bullfrog, Sri Lankan painted frog, Sri Lankan kaloula, Ceylon kaloula, Indian painted frog, or painted globular frog, is a species of narrow-mouthed frog found in Nepal, Bangladesh, southern and eastern India, and Sri Lanka up to an altitude of about 1300 metres. It can grow to an adult length of up to 75 millimetres(7.5 cm) long from snout to vent. It was originally described as a subspecies of Kaloula pulchra, ssp. taprobanica. The IUCN lists it as being of "Least Concern".
Phrynomedusa fimbriata, the spiny-knee leaf frog, is an extinct species of tree frog. It was endemic to Brazil, where the only known specimen was discovered near Paranapiacaba in the state of São Paulo. The type locality was given as "Alto da Serra". While the species might still exist, having only been found once in the 1898, no trace of any individuals have been discovered in successive expeditions.
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. The specific name anatipes refers to the "duck-like" feet of this frog, characterized by extensive webbing between the toes. Common name Santa Cecilia humming frog has been proposed for this species.
Chiasmocleis cordeiroi is a species of frog in the family Microhylidae. It is endemic to Bahia in eastern Brazil. It is known from Camamu, its type locality, and from few other localities on both sides of the De Contas River. The specific name cordeiroi honors Paulo Henrique Chaves Cordeiro, a Brazilian biologist. Common name Cordeiro's humming frog has been coined for this species.
Chiasmocleis crucis is a species of frog in the family Microhylidae. It is endemic to Bahia in eastern Brazil. It is known from Camamu, its type locality, and from the Serra Bonita Private Reserve of Natural Heritage in Camacan/Pau Brasil. The specific name crucis honors Carlos Alberto Gonçalves da Cruz, a Brazilian herpetologist.
Chiasmocleis hudsoni, also known as Hudson's humming frog, is a species of frog in the family Microhylidae. It is found in French Guiana, Suriname, Guyana, Guianan Venezuela, Colombia (Amazonas), and Amazonian Brazil. Chiasmocleis jimi has been included in this species but the most recent genetic analyses support its recognition as a distinct species; both species might include further distinct lineages that warrant recognition as species.
Chiasmocleis ventrimaculata, also known as the dotted humming frog, is a species of frog in the family Microhylidae. It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru. Its natural habitats are subtropical or tropical moist lowland forests, swamps, and intermittent freshwater marshes.
Rhombophryne is a genus of microhylid frogs endemic to Madagascar. It is currently estimated to include more than 23 species, but only 20 of these are currently described. The common name 'diamond frog' has been proposed and used for members of this genus.
Chiasmocleis royi, the reticulated humming frog, is a frog endemic to Bolivia, Brazil, and Peru. This frog often shares burrows with tarantulas in what may be a mutualistic or commensalistic symbiosis.
Chiasmocleis lacrimae, the central humming frog, is a frog in the family Microhylidae. It is endemic to Brazil, where it lives in lowland forest habitats.
