Yunganastes is a small genus of frogs in the family Strabomantidae found in southern Peru and central to northern Bolivia. They were formerly placed in the genus Eleutherodactylus as the "Eleutherodactylus fraudator group", subsequently moved to Pristimantis , before becoming recognized as a separate subgenus, and finally, a genus. Its sister taxon is the genus Pristimantis. [2] Yunganastes are endemic to the cloud forests and humid montane forests of the Cordillera Oriental of the Andes in Bolivia and southern Peru. [1]
The generic name Yunganastes is derived from yunga , the humid forests of the Andean valleys, and the Greek nastes for "dweller". This refers to the typical habitat of frogs in this genus. [1]
Yunganastes are robust-bodied and moderate to medium-sized frogs. Males can reach 52 mm (2.0 in) and females 63 mm (2.5 in) in snout–vent length. The limbs are moderately long. The head is as wide or wider than the body; the snout is short. The tympanum is visible, and the supra-tympanic fold is well-developed. The toes have rudimentary or no webbing. Males have a large vocal sac. The male advertisement call is single melodic whistle with frequency modulation and relatively low dominant frequency of about 1200–1500 Hz. [1]
There are five species: [2] [3]
Oreobates is a genus of frogs in the family Strabomantidae. Most species were formerly in the genus Ischnocnema, but were moved to this revalidated genus following a 2006 revision. Its sister taxon is Lynchius.
Pristimantis actinolaimus is a frog species in the family Strabomantidae. It is endemic to Colombia and only known from the vicinity of its type locality, El Estadero, in Samaná, Caldas Department, on the eastern slopes of the Cordillera Central. The specific name actinolaimus is derived from the Greek aktinos (=ray) and laimos (=throat) and refers to the radiating lines on the throat of this frog.
Yunganastes ashkapara is a species of frog in the family Strabomantidae. It is endemic to Bolivia and is known from the vicinity of its type locality in the Chapare Province and from Abra de la Cruz in the Manuel María Caballero Province. The specific name ashkapara is derived from Quechuan ashka meaning "a lot" and para for "rain", and refers to the very high rainfall in the region of the type locality.
Yunganastes bisignatus is a species of frog in the family Strabomantidae. It is endemic to the La Paz Department, Bolivia, and known from between the Inquisivi and Nor Yungas Provinces. It has been considered synonym of Pristimantis fenestratus but is now treated as valid species.
Pristimantis frater is a species of frog in the family Strabomantidae. It is endemic to Colombia and occurs on the eastern slopes of the Cordillera Oriental in the Norte de Santander, Boyacá, Casanare, Cundinamarca, and Meta Departments, as well as in the Serranía de la Macarena. The population in the Serranía de la Macarena might represent a distinct species. Common name Meta robber frog has been coined for it.
Yunganastes fraudator is a species of frog in the family Strabomantidae. It is endemic to Bolivia and found in the Cochabamba Department to the border with the Santa Cruz Department. It is sometimes known as Cochamba robber frog. Its specific name fraudator means "cheat" or "deceiver" and refers to its resemblance with Gastrotheca marsupiata.
Yunganastes mercedesae is a species of frog in the family Strabomantidae. It is found in Bolivia and southern Peru. It is sometimes known as Mercedes' robber frog. It is named after Mercedes S. Foster, who collected the holotype and was acknowledged for her herpetological collection efforts in South America.
Pristimantis moro, also known as La Hondura robber frog, is a species of frog in the family Strabomantidae. It is found in lowland western Colombia, the Pacific versant of Panama, and the Atlantic versant of Costa Rica.
Yunganastes pluvicanorus is a species of frog in the family Strabomantidae. It is endemic to Bolivia and found on the eastern slopes of the Cordillera Oriental in the Cochabamba and Santa Cruz Departments.
Pristimantis quaquaversus is a species of frog in the family Strabomantidae. It is found on the lower Amazonian slopes of the Andes from northern Ecuador south to the Cordillera de Cutucú and Cordillera del Cóndor as well as the adjacent northern Peru.
Oreobates sanderi is a species of frog in the family Strabomantidae. It is found in north-western Bolivia and nearby south-eastern Peru. It is not considered threatened by the IUCN.
Oreobates saxatilis, also known as Tarapoto big-headed frog, is a species of frog in the family Strabomantidae. It is endemic to Peru and known from near its type locality near Tarapoto as well as from the Río Tambo District in the Satipo Province, Panguana in the Puerto Inca Province, and Río Kimbiri in the La Convención Province.
Lynchius simmonsi, also known as Simmons' big-headed frog, is a frog species in the family Strabomantidae. It is endemic to southern Ecuador where it is known from the type locality in the Cordillera del Cóndor, Morona-Santiago Province as well as from the adjacent Zamora-Chinchipe Province. Its natural habitat is subtropical old-growth forest. The type series was collected by day on the forest floor. The area was mined during the Cenepa War in 1995, and has consequently seen little human activity, although this may change through a proposed road.
Oreobates pereger, also known as the Ayacucho Andes frog, is a species of frog in the family Strabomantidae. It is endemic to Peru where it is known from the eastern slopes of the Cordillera Oriental and Cordillera Vilcabamba mountain ranges.
The Strabomantidae, sometimes called cloud forest landfrogs, are a family of frogs native to South America. These frogs lack a free-living larval stage and hatch directly into miniature "froglets". This family includes Pristimantis, the most speciose genus of any vertebrate. Based on molecular dating, the Holoadeninae in particular appears to have originated in the Eocene. The Oligocene-Miocene transition was also found to be important to their biogeographical history. However, the lack of Holoadeninae fossils and limited nucleotide data ambiguates the results, by the authors' admission.
Bryophryne is a genus of frogs in the family Strabomantidae. These frogs are endemic to south-eastern Peru in the Cusco Region, with an undescribed species from the Puno Region. Their range is separated from that of Phrynopus by the Apurímac River valley.
Oreobates ayacucho is a species of frogs in the family Strabomantidae. It is endemic to Peru and known from a few localities in the Ayacucho Region in the Peruvian Andes. The species is only known from 11 specimens.
Noblella is a genus of frogs in the family Strabomantidae. They are found on the eastern slopes of the Andes and in the Amazon Basin in Colombia, Ecuador, Peru, Bolivia, and western Brazil. The name refers to Gladwyn K. Noble, who described the first species.
Phyllomedusa chaparroi is a species of treefrog in the subfamily Phyllomedusinae endemic to Peru. Scientists have only seen it in two places. This frog has been observed between 537 and 650 meters above sea level.
Pristimantis jubatus is a species of frog in the family Strabomantidae. It is endemic to Cordillera Occidental and is known from the vicinity of its type locality in the Munchique National Park and from Farallones de Cali. The specific name jubatus is Latin for "crested" and refers to the cranial crests of this frog.
