From the IUCN Red List Species Account:


Range Description

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).
