This species is known from the general vicinity type locality, on km 144 on the road from El Dorado to Santa Elena de Uairén (05 53N, 61 23W), at an elevation of 1,210m asl, in Bolívar state, southeastern Venezuela. It has been recorded from 500-1,500m asl. It potentially also occurs in Brazil but there are no records from there as yet. It almost certainly occurs more widely.
Habitat and Ecology
Its habitat in Bolívar state has been defined as the marginal vegetation of oligotrophic wetlands (Gorzula and Señaris 1999). Males of this species have been found calling from blades of grass in swallow marsh and from grass along a sluggish stream. Amplectant pairs have been found about 1m above water on a bush (Duellman 1997). By day, it hides beneath stones. Tadpoles apparently develop in shallow pools (about 15cm deep). It has also been recorded from around temporary waterbodies in tropical rainforest and its edge.
It is a common species.
There are no known threats to this species at present. It occurs in a region of limited human impact.
Some populations might be protected within Canaima National Park in Venezuela.
