This species is known from the Albarregas River and its tributaries in Monte Zerpa, north of the city of Mérida, in Venezuela. It has been recorded from altitudes between 1,975 and 2,400m asl. The exact limits of its distribution are still very unclear.
Habitat and Ecology
It lives on the upper surface of leaves about 2m above the streambed in montane cloud forests, where the eggs are also deposited. When hatched the larvae drop into the stream below where they develop further.
It is an uncommon species.
This species is sometimes threatened by periodic fast floods that devastate the margins of the streams, affecting the vegetation and the egg masses deposited there, which can result in the loss of the reproductive effort for one particular season. Introduced trout in the streams may prey on the species' larvae, and water pollution is also a threat.
Populations of this species are found within Parque Nacional Sierra de La Culata and Parque Nacional Sierra Nevada.
Red List Status
