Atelopus is a large genus of Bufonidae, commonly known as harlequin frogs or toads, from Central and South America, ranging as far north as Costa Rica and as far south as Bolivia. Atelopus species are small, generally brightly colored, and diurnal. Most species are associated with mid-to-high elevation streams.
The bleeding toad, fire toad or Indonesian tree toad is a species of true toad in the amphibian family Bufonidae, endemic to Java, Indonesia. L. javanica was, formerly, synonymous with the bleeding toad prior to its description as a distinct species in 2018, although the degree of differentiation between these species is low. The bleeding toad is listed as a critically endangered species due to a drastic population decline. The factors behind this decline are unclear, but appear consistent with the global spread of chytrid fungus, a particularly lethal fungal spore for frogs and toads; once infected, the animals develop a condition known as chytridiomycosis before ultimately dying. it is estimated there are less than 250 individuals of the species.
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. Once listed as extinct by the IUCN, it was rediscovered in 2016 after more than two decade with no sightings.
The starry night harlequin toad is a species of toad in the family Bufonidae endemic to the Sierra Nevada de Santa Marta, Colombia. Its natural habitats are sub-Andean and Andean forests, sub-páramo and páramo at 2,000–3,500 m (6,600–11,500 ft) above sea level. It is named after its unique coloration, being largely black with white spots.
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.
The Guajira stubfoot toad or Carrikeri harlequin frog is a species of toad in the family Bufonidae. It is about 5 cm (2.0 in) long and typically black, though some populations have orange coloration. This species is endemic to the Sierra Nevada de Santa Marta mountain range of northern Colombia. It is critically endangered because of the chytrid fungus, Batrachochytrium dendrobatidis, and habitat destruction due to agriculture. The species had not been seen from 1994 until it was rediscovered in early 2008.
Atelopus certus, the Darien stubfoot toad or Toad Mountain harlequin frog, is a species of toad in the family Bufonidae endemic to Panama.
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.
Atelopus coynei, the Rio Faisanes stubfoot toad, is a species of toad in the family Bufonidae endemic to Ecuador. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, and rivers. It is threatened by habitat loss.
Atelopus cruciger, also known as the Veragua stubfoot toad or Rancho Grande harlequin frog, is a species of toad in the family Bufonidae. It is endemic to Venezuela and is known from the central Venezuelan Coastal Range. The species was already suspected to be extinct because, despite considerable effort, none had been found since 1986. However, in 2003, a small population was found, with few other locations discovered later. It is mainly threatened by chytridiomycosis. It is locally called sapito rayado.
The Cayenne stubfoot toad, known in French as atélope jaunâtre, is a species of toad in the family Bufonidae found in northeastern French Guiana and in the adjacent Brazilian state Amapá. Its natural habitats are lowland primary forest where it is known from near fast-flowing, small streams. It is locally common. There are no major threats at present.
Atelopus spumarius is a species of toad in the family Bufonidae. It is native to Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru and Suriname.
Atelopus franciscus, the Central Coast stubfoot toad, is a species of toad in the family Bufonidae, endemic to the central coastal region of French Guiana. It is a locally common, diurnal species found near fast-flowing small streams and creeks in lowland rainforest. Many authors have suggested this taxon might be a synonym of Atelopus flavescens. It is threatened by habitat loss.
Atelopus glyphus, the Pirri harlequin frog or Pirri Range stubfoot toad, is a species of toad in the family Bufonidae found in Colombia and Panama within the Northwestern Andean montane forests. Its natural habitats are subtropical or tropical moist montane forests and rivers.

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 petriruizi, more commonly known as the painted stubfoot toad, is a species of toad in the family Bufonidae. Endemic to Colombia, the toad's natural habitats are subtropical or tropical moist montane forests and rivers. Threatened by habitat loss, the Ateopus petriruizi is currently classified as critically endangered, and was placed on the IUCN red list in 2017. Currently, there may be less than 49 remaining mature A. Petriruizi.
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 spurrelli is a species of toad in the family Bufonidae. It is endemic to Colombia and occurs in the Pacific lowlands and foothills of the Cordillera Occidental.
