This species is known only from the type locality and one other location; it is known from lowland rainforest near Timbo, Vaupés department, Colombia, and at Tarapaca/Leticia, Amazonas department, Colombia, at 170m asl (J. Lynch, unpubl. data).
Habitat and Ecology
It lives in lowland rainforest where it occurs in the vegetation. It is an arboreal and nocturnal species. Its reproductive sites are unknown, but breeding is likely to take place in water.
Few specimens of this species are known, but it was collected in Tarapaca in 2002.
Both localities where this species is confirmed are threatened by habitat destruction caused by expanding cattle ranching activities. However, a large area of undisturbed forest occurs between these points where this species is also likely to occur.
It is possible that it occurs in El Pure National Park. Surveys are needed to establish its range.
Red List Status
Least Concern (LC)
Although this species is known mainly from isolated records, it is listed as Least Concern in view of its likely wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
This species was previously with the genus Hyla, but was recently moved to Scinax (Faivovich, et al., 2005).
