CR Atelopus galactogaster Rivero and Serna, 1993 “1991”<br />
Critically Endangered A3ce<br />
Order, Family: Anura, Bufonidae<br />
Country Distribution: Colombia<br />
Current Population Trend: Unknown<br />

Geographic Range This species is known from two localities within Parque Nacional Natural Paramillo, in Antioquia<br />
Department, on the northern slope of the western Andes, in Colombia, at 1,500m asl.<br />
Population This species is known only from ten specimens; however, there has been no recent survey work within<br />
its range.<br />
Habitat and Ecology Both of the known localities are within primary forest, but no other information is available<br />
on the species’ habitat requirements or breeding habits.<br />
Major Threats The most serious risk to this species is chytridiomycosis, which has had a devastating impact on<br />
other high-altitude species of Atelopus.<br />
Conservation Measures Both known localities of the species are within Parque Nacional Natural Paramillo. Further<br />
research into the species’ range, ecological requirements, and population status is needed, in particular to determine<br />
if it occurs outside its current known range. Given the likely threat of chytridiomycosis, disease management and<br />
captive-breeding programmes might be required.<br />

CR Atelopus glyphus Dunn, 1931<br />
Critically Endangered A3ce<br />
Order, Family: Anura, Bufonidae<br />
Country Distribution: Colombia, Panama<br />
Current Population Trend: Decreasing<br />

Geographic Range This species occurs in eastern Panama, in the Serranía de Pirre, and also the Chocó of Colombia,<br />
at 884-1,500m asl.<br />
Population It is considered to be generally common within its known range. It was still common in September 2002<br />
in the Serranía de Pirre, above Cana, in eastern Panama (R. Ibáñez pers. obs.).<br />
Habitat and Ecology It is a terrestrial species of tropical montane forest, with breeding and larval development taking<br />
place in forest streams. There is no information on whether or not this species can survive in degraded habitats.<br />
Major Threats The major threat is likely to be a future catastrophic decline, due to chytridiomycosis, as has occurred<br />
in many other species of Atelopus. Additional threats include habitat loss due to agricultural development (including the<br />
planting of illegal crops), logging, and human settlement, and pollution resulting from the spraying of illegal crops.<br />
Conservation Measures The species has been recorded from two protected areas: Parque Nacional Darién (a World<br />
Heritage Site) in Panama and Parque Nacional Natural los Katíos in Colombia. In view of the severe risk of chytridiomycosis,<br />
the status of this species should be closely monitored, and ex-situ populations should be established.<br />

CR Atelopus guanujo Coloma, 2002<br />
Critically Endangered A2ace<br />
Order, Family: Anura, Bufonidae<br />
Country Distribution: Ecuador<br />
Current Population Trend: Decreasing<br />
© Luis A. Coloma<br />
Geographic Range This species is known only from the type locality and its immediate vicinity (Guaranda, Gallo<br />
Rumi) in the Chimbo Basin of the Cordillera Occidental of Ecuador, in the province of Bolívar. These localities are<br />
between 2,600 and 2,923m asl in the upper Río Chimbo Valley (Coloma 2002).<br />
Population It is a rare species, and the most recent record dates from April 1988 (Coloma 2002). Since then, survey<br />
efforts have been unsuccessful in finding any individuals, suggesting a serious population decline and possible<br />
extinction.<br />
Habitat and Ecology This species is an inhabitant of humid cloud forest. Frogs have also been collected in disturbed<br />
montane cloud forest areas (Coloma 2002). There is no specific information on breeding habits, but it is likely to be<br />
similar to other Atelopus species, with breeding and larval development taking place in streams.<br />
Major Threats The most likely cause of the species’ population decline is chytridiomycosis. Habitat loss is also a<br />
major threat, due to agriculture (crops, livestock, and wood plantations), logging, and infrastructure development for<br />
human settlement. Invasive species such as dogs, cats, and chickens also prey on this species.<br />
Conservation Measures The known range of the species does not include any protected areas. Surveys are needed<br />
to establish whether or not this species still persists in the wild. In view of the severe threat of chytridiomycosis, any<br />
surviving populations should be maintained in captivity.<br />

CR Atelopus guitarraensis Osorno Muñoz, Ardila-Robayo and Ruíz-Carranza, 2001<br />
Critically Endangered A3ce<br />
Order, Family: Anura, Bufonidae<br />
Country Distribution: Colombia<br />
Current Population Trend: Decreasing<br />
Geographic Range This species is only known to occur in the<br />
Laguna de Guitara, Parque Nacional Natural Sumapaz, Meta Department,<br />
Colombia, at 3,400m asl.<br />
Population It is rare, being recorded only from two expeditions<br />
conducted in 1975 and 1990. There has been no subsequent survey<br />
work for this species.<br />
Habitat and Ecology It lives and reproduces in streams in páramo<br />
habitats.<br />
Major Threats The most serious risk to this species is chytridiomycosis,<br />
which has had a devastating impact on other high-altitude<br />
species of Atelopus. Its habitat is threatened by fi res caused by<br />
cattle ranchers.<br />
Conservation Measures This species occurs in the Parque Nacional<br />
Natural Sumapaz. Further work is required to determine the population<br />
status of this species; given the threat of chytridiomycosis,<br />
a captive-breeding programme might need to be established for<br />
this species.<br />
