Scientific Name:	Hyloxalus elachyhistus
Species Authority:	(Edwards, 1971)
Synonym/s:	Colostethus elachyhistus Edwards, 1971 Colostethus elachyhistus Edwards, 1971

Assessment Information [top]

Red List Category & Criteria:	Endangered A2ac; B2ab(iii,iv,v) ver 3.1
Year Published:	2004
Assessor/s:	Javier Icochea, Luis A. Coloma, Santiago Ron
Reviewer/s:	Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Contributor/s:
Justification: Listed as Endangered because of a drastic population decline estimated to be more than 50% over the last three generations (generation length being assumed to be five years); and because its area of occupancy is less than 500 km2, its distribution is severely fragmented, and there is a continuing decline in the extent and quality of its habitat, area of occupancy, number of locations, and number of mature individuals.

Geographic Range [top]

Range Description:	This species occurs on the western slopes of the Andes in southern Ecuador, at elevations of 850-2,760m asl. It also occurs on the Pacific and Amazonian slopes of the Andes in the Huancabamba depression, Piura Department, northern Peru, at 600-1,800m asl.
Countries:	Native: Ecuador; Peru

Population [top]

Population:	It is an uncommon species. In Ecuador, populations from Loja and nearby localities at the higher altitudes of its range seem to be extinct, but lowland populations are still extant with records as recently as 2003.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	It lives in dry and humid lowland and premontane forest, and occurs near streams, especially in dry forests. The larvae presumably develop in streams.
Systems:	Terrestrial; Freshwater

Threats [top]

Major Threat(s):	The cause of the declines at high elevations, which have taken place even in suitable habitat, could be due to chytridiomycosis. Habitat destruction and degradation, in particular due to agricultural activities, is also a threat to this species, and the species may also be impacted by invasive alien species and pollution.

Conservation Actions [top]

Conservation Actions:	It does not occur in any protected areas, and some form of formal habitat protection is urgently needed. Further survey work is needed to determine whether any animals survive around Loja and other nearby localities.
