This species occurs on the western slope of the Cordillera Oriental, in Boyacá and Santander Departments, Colombia, at 1,630-2,400m asl.
Habitat and Ecology
It lives in streams in cloud forests, and also in secondary forest. The eggs are laid on vegetation, and the larvae develop in water.
It is known to be common, although there has been no survey work for this species since 1987.
Habitat loss due to agriculture and cattle ranching, and predation by introduced trout, represent the major threats to this species.
It occurs in one protected area, the Santuario de Fauna y Flora Guanentá Alto Río Fonce, where work has been under way by The Nature Conservancy in conjunction with Fundación Natura and other partners to support the expansion of the existing reserve, as well as the the creation of a new public protected area.
Red List Status
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat on the Eastern Cordillera of the Colombian Andes.
This species was previously included in the genus Hyla but has recently been moved to the resurrected genus Hyloscirtus (Faivovich et al. 2005). Ruíz-Carranza, Ardila-Robayo and Lynch (1996) noted that one of the paratypes of this species is referrable to Hyloscirtus palmeri.
