This species is restricted to the summit of the Chimantá Massif, where two specimens were collected on the north-western edge of the Amurí tepui, at 2,100 and 2,600m asl, in Venezuela. These two specimens were collected 45km apart and, according to Walls (1994), could possibly represent two species. This species could occur more widely.
Habitat and Ecology
It occurs in high montane environments, on the tops of tepui, where one specimen was taken from within the root mat of a Bonnetia roraimae tree. This species presumably breeds by larval development, but it is not known where the larvae develop.
It is probably a common frog at the type locality.
There is no information known about threats to this species, but it occurs in a region of very limited human impact.
Its range is within Parque Nacional Canaima. Further taxonomic research is required to determine whether or not the two specimens collected so far are conspecific.
