This species is known only from the type locality: about 2km ESE by air from Agua de Obispo, in the state of Trujillo, Venezuela, at 2,250m asl (9.42'N, 70.05'W).
Habitat and Ecology
It occurs in small cold-water streams in cloud forest. The eggs are laid on land and the male protects the eggs. When hatched the male carries the larvae on his back to water where they develop further.
It is a very rare species that appears to have declined. Several attempts to find it in recent years have failed, and it is still known only from the time it was first described.
Habitat loss and degradation due to agriculture (both crops and livestock) and road construction, is the major threat to the species. The locality is near the headwaters of a stream and thus could have been affected by a drought in the past. The species could also potentially be affected by disease, such as chytridiomycosis.
There is a population within Parque Nacional Dinira. Surveys are urgently needed to determine the population status of this species as well as some of its threats.
