This species is known only from the type locality, on top of Cerro Marahuaca, in Amazonas state (03° 40'N; 65° 27'W), at 2,600m asl, in Venezuela.
Habitat and Ecology
It inhabits high montane tepui habitat. It breeds by direct development, perhaps with internal fertilization.
The population status of this species is not known.
There are no current major threats, but its restricted range makes it susceptible to threatening processes such as wildfire.
There is a population within Parque Nacional Duida-Marahuaca. There is a need for close population monitoring of this species, particularly since it is restricted to a single location.
