This species is known from the type locality in North Teniente Lopez, between Río Pastaza and Río Tigre, northern Departamento Loreto, Peru; and from three single localities in Ecuador. While the species is known from only a few sites it is expected to occur more widely in the suitable habitat between these areas. It occurs up to 450m asl.
Habitat and Ecology
Its habitat is lowland tropical rainforest. At Loreto, the holotytpe was found in a permanent or semi-permanent pond supporting Heliconia in a depression in rainforest. This specimen was perched on a leaf of a vine 4m above the ground; the vine was attached to a tree at the edge of the forest pond (Duellman and Mendelson III, 1995). The species deposits eggs on leafs overhanging temporary ponds; the larvae develop in the pools. It is not present in degraded habitat.
It is not an abundant species.
The most western part of the Ecuadorian range is suffering from habitat loss (agriculture, logging etc.).
In Ecuador, its geographic range overlaps with Parque Nacional Yasuní. It is not found in any Peruvian protected areas.
This species was previously within the genus Phyllomedusa but has recently been moved to the genus Hylomantis (Faivovich, et al., 2005). It might be conspecific with Hylomantis buckleyi.
