This species is known from several localities in the Cordillera de la Costa, including La Sierra in Cojedes State, and Sierra de Aroa in Yaracuy State, in Venezuela. It has been recorded from 100-700m asl.
Habitat and Ecology
It inhabits montane forest environments, where it occurs along streams. It lays its eggs on the under side of leaves overhanging streams, and when hatched the larvae fall into the stream below where they develop further.
It is probably an uncommon species.
The major threat to this species is habitat loss due to agriculture (both crops and livestock), as well as logging. Avalanches are a potential threat along the coast, especially during heavy rainfall periods.
It is present in several protected areas, including Parque Nacional Henri Pittier and Rancho Grande.
Red List Status
Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat in the Venezuelan coastal range.
In the past, some specimens of this species were considered to be Hyalinobatrachium fleishmanni.
