This species is known from the Andes of Venezuela, in the states of Mérida and Trujillo. It has been recorded from 1,800-3,000m asl. Records from Sierra del Turimiquire, in Sucre and Monagas States, are misidentifications.
Habitat and Ecology
It is found alongside streams in cloud forests. The eggs are laid on leaves overhanging water, and when hatched the larvae fall into the water below.
It was formerly considered to be an uncommon species, and it t is possible that it is decreasing in some places due to habitat loss. However, in some places like Monte Zerpa, north of the city of Mérida, this frog has replaced a formerly abundant species (Hyla platydactyla) that has undergone serious declines.
The major threat to this species’ habitat is agricultural development, involving both cultivation of crops and livestock grazing. Predation by introduced trout is also a problem.
Its range includes Parque Nacional Sierra Nevada, Parque Nacional Sierra de La Culata and Parque Nacional Guaramacal.
Red List Status
Near Threatened (NT)
Listed as Near Threatened because although the species might not to be in decline, its Extent of Occurrence is less than 5000 km2, thus making the species close to qualifying for Vulnerable.
This species was previously within the genus Hyla but has recently been moved to the resurrected genus Hyloscirtus (Faivovich et al. 2005).
