Telmatobius is a genus of frogs native to the Andean highlands in South America, where they are found in Ecuador, Peru, Bolivia, northwestern Argentina and northern Chile. It is the only genus in the family Telmatobiidae. Some sources recognize Batrachophrynus as a valid genus distinct from Telmatobius.
Telmatobius brachydactylus, the Amable Maria frog, is an endangered species of frog in the family Telmatobiidae.
Telmatobius macrostomus, also known as the Lake Junin (giant) frog or Andes smooth frog, is a very large and endangered species of frog in the family Telmatobiidae. This completely aquatic frog is endemic to lakes and associated waters at altitudes of 4,000–4,600 m (13,100–15,100 ft) in the Andes of Junín and Pasco in central Peru. It has been introduced to slow-moving parts of the upper Mantaro River, although it is unclear if this population still persists.
Telmatobius atahualpai is a species of frog in the family Telmatobiidae. It is endemic to the Cordillera Central of northern Peru and found in the San Martín and Amazonas Regions at 2,600–4,000 m (8,500–13,100 ft) asl.
Telmatobius brevipes is a species of frog in the family Telmatobiidae. It is endemic to Peru. Its natural habitats are subtropical or tropical moist montane forest, subtropical or tropical high-altitude shrubland, subtropical or tropical high-altitude grassland, rivers, arable land, and canals and ditches.
Telmatobius brevirostris is a species of frog in the family Telmatobiidae. It is endemic to Peru. Its natural habitats are moist montane forest, high-altitude shrubland, and rivers. It does not occur in cultivated areas. It is threatened by habitat loss.
Telmatobius colanensis is a species of frog in the family Telmatobiidae. It is endemic to northern Peru and only known from its type locality on the Cordillera Colán, near La Peca, Amazonas Region.
Telmatobius degener is a species of frog in the family Telmatobiidae. It is endemic to the La Libertad Region of Peru and only known from its type locality between Otuzco and Huamachuco, at 3,290 m (10,790 ft) asl. The type locality is in the very humid subalpine páramo. The frogs were active by day and found in pools and running water in a densely vegetated roadside marsh in an open pasture.
Telmatobius gigas is a critically endangered species of frog in the family Telmatobiidae. It is endemic to the Huayllamarca River at an altitude of about 4,000 metres (13,000 ft) in the Carangas Province in Bolivia. Its tiny range makes it highly vulnerable to pollution, and it may also be threatened by over-harvesting for medicinal use and the disease chytridiomycosis. As suggested by its scientific name, this is a very large species of frog with a snout-vent length of up to 10.9 centimetres (4.3 in) in females. In the genus Telmatobius, only two other threatened species, the Titicaca water frog and Lake Junin frog, are larger. T. gigas is very closely related to the smaller and more widespread T. marmoratus, and they might be conspecific.
Telmatobius intermedius is a species of frog in the family Telmatobiidae. It is endemic to Peru. Its natural habitats are subtropical or tropical high-altitude shrubland, subtropical or tropical high-altitude grassland, and rivers.
Telmatobius jelskii, also known as the Acancocha water frog, is a near-threatened species of frog in the family Telmatobiidae, endemic to the Andes of central Peru. This semiaquatic frog is found in and near streams and ditches at altitudes of 2,700–4,500 m (8,900–14,800 ft). It breeds in streams.
Telmatobius marmoratus, the marbled water frog, is a vulnerable species of frog in the family Telmatobiidae. The most widespread species in the genus, it is found in the Andean highlands of Bolivia, northern Chile and southern Peru. It may also occur in northwestern Argentina, but the taxonomic position of this population is unclear. This semiaquatic frog is found in and near streams, rivers, waterfalls, lakes and ponds.
Telmatobius mayoloi is a species of frog in the family Telmatobiidae. It is endemic to Peru. Its natural habitats are subtropical or tropical high-altitude grassland and rivers. This species is primarily found in central Peru. They can also be found in Andes, Ecuador, Chile, and Argentina in high elevation areas ranging from 1,300 to 5,400 meters high.
Telmatobius necopinus is a species of frog in the family Telmatobiidae. It is endemic to Peru. Its natural habitats are subtropical or tropical moist montane forest and rivers.
Telmatobius pefauri is a species of frog in the family Telmatobiidae. It is endemic to extreme northern Chile. It was already feared that this species is extinct, but recent research has suggested that the species is extant at several localities in the Arica y Parinacota Region, albeit at low numbers. Furthermore, morphological and genetic data suggest that Telmatobius zapahuirensis is a synonym of Telmatobius pefauri. Common name Arico water frog has been coined for this species.
Telmatobius peruvianus, also known as the Peru water frog, is a species of frog in the family Telmatobiidae. This semiaquatic frog is endemic to Andean highlands in southeastern Peru and far northern Chile where found in streams and small rivers. It is threatened by habitat loss, pollution, collection for human consumption and infection by chytrid fungi, and it has not been seen in Chile since 1986.
Telmatobius rimac is a species of frog in the family Telmatobiidae. It is endemic to Peru. Its natural habitats are subtropical or tropical high-altitude shrubland, subtropical or tropical high-altitude grassland, rivers, arable land, pastureland, and canals and ditches.
Telmatobius thompsoni is a species of frog in the family Telmatobiidae. It is endemic to Peru. Its natural habitats are subtropical or tropical high-altitude shrubland, rivers, swampland, freshwater marshes, and intermittent freshwater marshes.
Telmatobius truebae is a species of frog in the family Telmatobiidae. It is endemic to Peru. Its natural habitats are subtropical or tropical moist montane forest, rivers, and canals and ditches.
Telmatobius culeus, commonly known as the Titicaca water frog, is a medium-large to very large and endangered species of frog in the family Telmatobiidae. It is entirely aquatic and only found in the Lake Titicaca basin, including rivers that flow into it and smaller connected lakes like Arapa, Lagunillas and Saracocha, in the Andean highlands of Bolivia and Peru. In reference to its excessive amounts of skin, it has jokingly been referred to as the Titicaca scrotum (water) frog.
