Ansonia is a genus of true toads found in south India, northern Thailand, Malay Peninsula, Tioman Island, Borneo, and Mindanao (Philippines). These small forest species spawn in streams and have torrent-adapted tadpoles. Common name stream toads has been coined for the genus, although individual species are also being referred to as slender toads.
The Carchi Andes toad, Rhaebo colomai, is a species of toad endemic to the western slopes of the Andes in northern Ecuador and southern Colombia. It is listed as an endangered species due to a restricted range and habitat loss.
The bleeding toad, fire toad, or Indonesia tree toad is a species of "true toad", family Bufonidae, endemic to Java, Indonesia. Leptophryne javanica was included in this species prior its description as a distinct species in 2018, although the degree of differentiation between these species is low. Bleeding toad is listed as a critically endangered species due to a drastic population decline. The reasons of this decline are unclear, but the decline is consistent with chytridiomycosis, despite ambiguous identification.
Adenomus kelaartii is a species of toad in the family Bufonidae. It is endemic to Sri Lanka, where it is found in the south-west of the island at elevations between 30 and 1,230 m. The specific name kelaartii honours Edward Frederick Kelaart, a Ceylonese-born physician and zoologist.
Malcolm's Ethiopian toad or the Ethiopian mountain toad, Altiphrynoides malcolmi, is a species of toad in the family Bufonidae endemic to the Bale Mountains of Ethiopia. Its natural habitats are Schefflera-Hagenia-Hypericum forests and Afro-alpine moorland, and the transition zone in between. It is threatened by habitat loss and is listed by the IUCN as being an "endangered species".
Rhaebo olallai is a species of toad in the family Bufonidae endemic to Ecuador. Its common name is Tandayapa Andes toad, after its type locality, Tandayapa, in the Pichincha Province); the species has not been seen there after 1970, despite search efforts. It is only known from another locality in the Imbabura Province of Ecuador. It has also been reported from one locality on the Colombian Massif, Nariño Department, Colombia, but these have been shown to represent Rhaebo colomai.
Ansonia malayana is a species of toad in the family Bufonidae. It is also known as Malayan slender toad, Malaya stream toad, and pigmy false toad. It is found on the Malay Peninsula, from the Kra Isthmus (Thailand) southward to Peninsular Malaysia. However, its precise distribution in Thailand is poorly known as it may have been confused with Ansonia kraensis, described as a new species in 2005; it may also represent more than one species.
Ansonia spinulifer, also known as spiny slender toad or Kina Balu stream toad, is a species of true toad in the family Bufonidae. It is found in Sarawak and Sabah, northern Borneo (Malaysia), and presumably also in Kalimantan on the Indonesian part of the island.
Atelopus balios, the Rio Pescado stubfoot toad, is a species of toad in the family Bufonidae. It is endemic to southwestern Ecuador, with records from Pacific lowlands in Azuay, Cañar, and Guayas Provinces. It is a rare species that was already suspected to be extinct, but a single specimen was discovered in 2011 by a team from Conservation International during a hunt for missing amphibians. The decline in amphibian populations is well documented. The Atelopus balios is Critically Endangered as a result of the widespread amphibian Chytridiomycosis fungus that has decimated other amphibian populations. There are only 10 known findings of the tadpole, Atelopus balios.
Nannophryne apolobambica is a species of toad in the family Bufonidae. It is endemic to Bolivia and only known from its type locality on the banks of Pelechuco River, Cordillera Apolobamba, in the Franz Tamayo Province of northwestern Bolivia. Its natural habitat is tropical cloud forest. Active toads were found on the forest floor and paths both day and night. It is threatened by habitat loss. The type locality is partly within the Madidi National Park.
Blomberg's toad, also known as the Colombian giant toad, is a very large species of toad in the family Bufonidae. It is found in rainforests at altitudes between 200 and 650 metres in western Colombia and northwestern Ecuador. It has been recorded in Florida in 1963, apparently because of pet escape or release, but did not get established.
Nannophryne corynetes, the Abra Malaga toad, is a species of toad in the family Bufonidae that is endemic to Peru and only found in the region of the type locality in the Urubamba Province. Its natural habitats are forest edges restricted to the zone of puna grassland directly adjacent to montane forest. Breeding habitat is unknown but probably aquatic. It is a very rare species but there are no immediate threats to it.
Bufotes luristanicus, the Lorestan earless toad or Lorestan toad, is a species of toad in the family Bufonidae. It is endemic to the Zagros Mountains in Iran and occurs at an altitude of 350–1,300 m (1,150–4,270 ft), most often near rocky outcrops or freshwater ponds, which it also uses for breeding. Little is known about this species, but it is not considered threatened overall. Some local populations may be threatened by habitat loss from human activities or drought.
Melanophryniscus sanmartini is a species of toad in the family Bufonidae. It is found in Uruguay and southernmost Brazil. Its natural habitats are grasslands and rocky outcrops. Reproduction takes place in small streams. It is threatened by habitat loss caused by exotic tree plantations.
The Palawan toadlet or white-striped flathead toad is a species of toad in the family Bufonidae. It is endemic to Palawan, the Philippines.
The Chirinda toad, Chrinda forest toad, Mashonaland toad or Boulenger's earless toad is a species of toad in the family Bufonidae with a restricted distribution in eastern Zimbabwe and western Mozambique.
Ansonia kraensis is a species of toads in the family Bufonidae. It is found on the Kra Isthmus, Thailand. It is morphologically similar to Ansonia malayana from Malaysia, but differs from it in ventral coloration and larval morphology. The exact threats are unknown but are likely forest loss for logging and agricultural expansion.
Bufo eichwaldi, commonly known as Eichwald's toad or the Talysh toad, is a species of true toads in the family Bufonidae. It was first described by Litvinchuk, Borkin, Skorinov and Rosanov in 2008 and is found in the Talysh and Elburz Mountains in Azerbaijan and parts of northern Iran. It was previously considered to be a subspecies of the Caucasian toad.
Nannophryne is a small genus of true toads, family Bufonidae, from South America. They are found in central Andean Peru south to southern Chile and adjacent Argentina.
Peltophryne is a genus of true toads in the family Bufonidae, from the Greater Antilles. With ten endemic species, Cuba hosts the highest diversity. Hispaniola has three endemics and Puerto Rico and the Virgin Islands combined has one.
