Range Description

This species is known from Guyana, Suriname and French Guiana. In Guyana it is known only from the type locality ("area north of Acarai Mountains, west of New River (ca. 02°N; 58°W), Rupununi District, Guyana") in extreme southern Guyana (Duellman and Hoogmoed, 1992). It is widespread in Suriname and French Guiana (Lescure and Marty (2001) provide a dot-map of the distribution in French Guiana).

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 0.9km2 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

Its ranges overlaps with all of the protected areas in Suriname and French Guiana.

Taxonomic Notes

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