This species can be found in the lowlands from central Panama to the eastern lowlands of San Blas, through to Colombia in the Magdalena Valley, Northwest Orinoquia and Upper Pacific region, and northern Venezuela and the Orinoco to Guyana and Suriname. It occurs up to 1,300m asl. In Venezuela, this species has been recorded from the states of Amazonas, Aragua, Bolívar, Carabobo, Distrito Federal, Falcón, Lara, Miranda, Monagas, Sucre, and Yaracuy. It is not reported from French Guiana (Lescure and Marty, 2001), where it seems to be replaced by Scinax proboscideus.
Habitat and Ecology
It is a nocturnal, largely arboreal species of sub-humid scrubby forest and moist savannahs found perched on low vegetation at the edges of temporary or permanent ponds close to moist forests. Breeding takes place in temporary ponds. This species can occur in modified habitats.
It is considered to be abundant in some localities.
General habitat loss by the destruction of natural forests is a major threat.
Although there are no specific conservation measures in place, the species has been recorded from a number of protected areas including Parque Nacional Chagres and Parque Nacional Soberania in Panama as well as in South America.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining to qualify for listing in a more threatened category.
This is most likely a species complex.
