Atelopus orcesi is a species of frog in the family Bufonidae. It has not been seen since 1988, and is believed to be possibly extinct.
Atelopus orcesi was first described in 2010. Its specific epithet honors Gustavo Edmundo Orcés Villagómez, a pioneering Ecuadoran zoologist. [2]
Atelopus orcesi is a medium-sized member of its genus, with males averaging 30mm in length and females averaging 40mm. Males and females can also be distinguished from each other by the longer, more slender forelegs females possess, and the distinct rows of warts down the sides of the males. Both sexes possess distinct X-shaped marks on the back of their heads. [2]
The species is only known from its type locality, in the eastern portion of Cordillera Occidental (Ecuador) in the Sucumbíos Province in Ecuador. Its preferred habitat consists of montane cloud forest. [2]
The only known specimens of Atelopus orcesi were collected in May of 1988 by Ana María Velasco. No further individuals have been seen since then despite surveys, including an intensive survey at the species' type locality in 2009. It's believed that its main threats are climate change and disease. [2] Chytridiomycosis is not known to have played a role in the population decline of Atelopus orcesi, but it is known to have caused other populations of amphibians in Ecuador to decrease dramatically. [3] In 2018, the IUCN listed the species as Critically Endangered and possibly extinct. [1]
Atelopus longirostris is a species of harlequin frog, a member of the family of true toads (Bufonidae). It has been recorded only in northern Ecuador. Records from Colombia probably represent different species. As of mid-2017, it is listed as extinct by the IUCN, but was rediscovered in 2016 after more than two decade with no sightings, likely because the IUCN last assessed it in 2004. The scientific name of this species means "long-snout" and the species has been named in Spanish as the jambato hocicudo. Common names longnose stubfoot toad, scrawny stubfoot-toad, and longnose sharlequin frog have been coined for it.
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.
Atelopus bomolochos, the Azuay stubfoot toad or Cuenca jambato frog, is a species of toad in the family Bufonidae. It is endemic to southern Ecuador and known from Cordillera Oriental in the Azuay, Cañar, and Loja Provinces.
Atelopus chiriquiensis, the Chiriqui harlequin frog or Lewis' stubfoot toad, is an extinct species of toad in the family Bufonidae that was found in the Cordillera de Talamanca in Costa Rica and western Panama. Its natural habitats were stream margins in lower montane wet forests and rainforests. Its elevational range was 1,400–2,500 m (4,600–8,200 ft) asl.
The elegant stubfoot toad or Pacific jambato frog is a species of toad in the family Bufonidae found in lowlands and Andean slopes of northwest Ecuador to 1,140 m (3,740 ft) asl and on the Gorgona Island, off southwest coast of Colombia. It was described by George Albert Boulenger in 1882 based on a specimen collected by Edward Whymper. It is known in Spanish as rana jambato del Pacífico or simply jambato del Pacífico.
Atelopus exiguus is a species of toad in the family Bufonidae. It is endemic to Ecuador and only known from the area of its type locality in the Azuay Province of southern Ecuador, in the sub-páramo and páramo of Cordillera Occidental. Common name Mazán jambato frog has been proposed for it.
Atelopus ignescens, the Jambato toad or Quito stubfoot toad or Jambato harlequin frog, is a species of toad in the family Bufonidae. It is endemic to the northern Andes of Ecuador. This once abundant species was believed to be extinct until its rediscovery in 2016. The specific name ignescens means "to catch fire", presumably in reference to the orange ventral color of this species.
Atelopus monohernandezii is a species of toads in the family Bufonidae. It is endemic to Colombia and only known from the vicinity of its type locality on the western slope of the Cordillera Oriental, Santander Department. It has not been observed after 1982 and the remaining population is believed to be very small, if surviving at all.
Atelopus mucubajiensis, also known as the Mucubaji stubfoot toad, is a species of toad in the family Bufonidae. It is endemic to the Mérida Andes of Venezuela. This once abundant species was last observed in 2004. It is likely extinct.
Atelopus pachydermus is a species of toad in the family Bufonidae. It is found in the Andes of northern Peru and southern Ecuador. Records from Colombia reflect the vagueness of the stated type locality, "Neu-Granada", encompassing territory part of several present-day countries. Other records outside the current range refer to other species. The most recent record of this very rare and possibly extinct species is from around 1995. However, there is a need to reassess the status of this species because of confusion with Atelopus podocarpus.
Atelopus palmatus is a species of toad in the family Bufonidae. It is endemic to the Cordillera Oriental of eastern Ecuador and is known from the Napo and Pastaza Provinces at elevations of 1,150–1,740 m (3,770–5,710 ft) above sea level. Its type locality is "Rio Pastaza".
Atelopus planispina is a species of toad in the family Bufonidae. It is endemic to the eastern slopes of the Andes of Ecuador. According to the IUCN SSC Amphibian Specialist Group, it is restricted to the Napo Province, although other sources suggest somewhat wider range. It has not been seen since 1985 and might already be extinct. Common names Planispina's harlequin frog, Napo stubfoot toad, and flat-spined atelopus have been coined for it.
Atelopus pulcher is a species of toad in the family Bufonidae. It is endemic to eastern Peru where it is found in the Huallaga River drainage; its range might extend to Ecuador. Its natural habitats are lowland and premontane tropical forests. It is a diurnal and terrestrial species that breeds in streams.
Atelopus senex is an extinct species of toad in the family Bufonidae. It was endemic to Costa Rica and known from the Cordillera Central and Cordillera de Talamanca at elevations of 1,100–2,200 m (3,600–7,200 ft) asl.
Atelopus petersi is a species of toads in the family Bufonidae. It is endemic to Ecuador and is known from the Cordillera Oriental in the Napo Province and more provisionally, in the Chimborazo Province. The specific name petersi honors James A. Peters, an American zoologist who collected the first specimens of this species in 1962 and provided a description under the name Atelopus pachydermus. Common names Peters' stubfoot toad and Peters' jambato toad have been coined for it.
Atelopus onorei is a small species of bright yellow and green toads in the family Bufonidae. It is endemic to Ecuador and is only known from the vicinity of its type locality on the western slope of the Cordillera Occidental in the Azuay Province. It has not been seen since 1990 and may now be extinct, but it is possible that overlooked populations remain.
Atelopus ardila is a species of frog in the family Bufonidae. It has not been seen since 1992, and is believed to be possibly extinct.
Atelopus pastuso is a species of frog in the family Bufonidae. It has not been seen since 1993, and is possibly extinct.
