From the IUCN Red List Species Account:


Range Description

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.

Major Threats

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.
