This species is known from the states of Guarico and Miranda, in the central part of the coastal forest range of Venezuela, between 150 and 750m asl.
Habitat and Ecology
It occurs along the banks of fast-flowing streams in primary humid lowland forests. The eggs are deposited under decaying leaves on the forest floor. The larvae are then presumably carried on the backs of the males to streams where they develop further, as with other members of the genus.
Its population status is not known, although there have been recent collections of specimens in Parque Nacional Guatopo.
Agriculture was a threat to this species in the past but this region is now within a protected area. The disturbance of the habitat by tourists is a major threat, and chytridiomycosis cannot be ruled out as a future threat.
The range of this species includes at least one protected area (Parque Nacional Guatopo), in which it is widely distributed.
