This species is known only from the vicinity of the type locality on the northeast plateau of Mount Ayanganna, and from Mount Wokomung, Guyana, between 1,490 and 1,550 m asl (MacCulloch and Lathrop 2002, MacCulloch et al. 2006). It is thought likely to have a very restricted range.
Habitat and Ecology
A high-elevation forest species. All specimens were collected at night on leaves or branches 1-5 m above ground. Females carry the eggs on their back and juveniles develop fully on their mother's back.
This was the most abundant amphibian species encountered on Mount Ayanganna (MacCulloch and Lathrop 2002).
There are no known threats, and all known localities for this species are in undisturbed, remote areas. Nonetheless, given its small range, it remains vulnerable to stochastic threatening processes.
The range of this species is within Kaieteur National Park. There is a need for close monitoring of the population status of this species.
Red List Status
Least Concern (LC)
Listed as Least Concern, although it is presently known from
only two locations, these are in remote, undisturbed areas, and there are no
known threats at this time.
This genus has recently been moved from the family Hylidae (Faivovich et al. 2005).
