From the IUCN Red List Species Account:


Range Description

This species is known from Venezuela (Gran Sabana in Bolívar state), and adjacent Guyana (in the region of Mount Roraima) from 700-1,400m asl. It might occur more widely.

Habitat and Ecology

It is a diurnal species that lives in tropical rainforest, usually adjacent to streams. Tadpoles have been found in La Escalera region amidst leaves in a slowly flowing, tannin-coloured stream on sandy substrate (Duellman 1997). It also uses streams with rocky streambeds. Males call from between rotten trunks, holes, mats of roots and from under rocks, usually near swampy areas. The tadpoles burrow in the sandy bottom of streams.


It is common within its range.

Population Trend


Major Threats

It occurs in an area of limited human impact, but local populations are probably impacted by agriculture, logging and human settlement

Conservation Actions

It occurs in Canaima National Park (Venezuela).

Red List Status

Least Concern (LC)


Listed as Least Concern in view of its probable wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
