From the IUCN Red List Species Account:

 

Range Description

The nominal subspecies is known only from the eastern sector of the Venezuelan Coastal Range, with records from Serranía del Interior, Macizo de Turimiquire, and Serranía de Paria in the states of Monagas and Sucre, at elevations of 190-1,200m asl. The subspecies H. o. tobagoensis is recorded from north-eastern Tobago in Trinidad and Tobago. Reports from Colombia are incorrect.

Habitat and Ecology

A nocturnal species that lives on Heliconia vegetation over-hanging cascading streams about 2-6m above the water in tropical rainforest. The eggs are laid on the underside of leaves, and the larvae develop in the water. It has been found only in mature, closed-canopy forest.

Population

It is a common species across its range.

Population Trend

Decreasing

Major Threats

In Venezuela, although some of its habitat is within protected areas, other areas are being lost due to human settlement and agricultural expansion. There are no known threats to the species in Tobago.

Conservation Actions

It occurs in the Parque Nacional Peninsula de Paria in Venezuela. The rainforest in which this species occurs in Tobago is protected in the Little Tobago Wildlife Sanctuary. Taxonomic work is required to investigate whether or not populations of this species from Tobago represent a distinct species.

Taxonomic Notes

It is possible that two species might be included in Hyalinobatrachium orientale in Venezuela, one being the species from the type locality, and the other an undescribed form from Macizo del Turimiquire. Animals on Tobago might also belong to a different species.
