From the IUCN Red List Species Account:

 

Range Description

This species is known from French Guiana and southern Guyana. In Guyana it is known only from the type locality of "area north of Acarai Mountains, west of New River, Rupununi District, Guyana" in extreme southern Guyana (Duellman and Hoogmoed 1992). It is presumed to occur in Suriname, but has not yet recorded (Ouboter and Jairam 2012).

Habitat and Ecology

This species inhabits lowland primary forest. They breed in very small tree holes in the canopy of the forest. Females feed the tadpoles by depositing unfertilised eggs in the tree holes. The larvae are oophagous.

Population

This species is often heard in the forest, but is difficult to see as it occurs very high up in the trees. Calling males were estimated at a density of 0.9 km-2 in primary forest in French Guiana (P. Gaucher pers. comm.).

Population Trend

stable

Major Threats

Clear-cutting of the forest might be a threat to this species in the future, but at present its habitat is generally secure.

Conservation Actions

Conservation Actions
This species' range overlaps with all of the protected areas in French Guiana. 

Research Needed
Further research is required into its distribution, population status, ecology and threats.

Red List Status

Least Concern (LC)

Rationale

Listed as Least Concern in view of its wide distribution and presumed large population.

Taxonomic Notes

This species was previously within the genus Phrynohyas which was recently synonymized with Trachycephalus (Faivovich et al. 2005).
