Taxon Name: Trachycephalus hadroceps (Duellman and Hoogmoed, 1992)
Common Name(s):
• French:
Rainette Marteau
Taxonomic Notes:
This species was previously within the genus Phrynohyas which was recently synonymized with
Trachycephalus (Faivovich, et al., 2005).
Assessment Information
Red List Category & Criteria:
Least Concern ver 3.1
Year Published:
2004
Date Assessed:
April 30, 2004
Annotations:
Needs Updating
Justification:
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is
unlikely to be declining fast enough to qualify for listing in a more threatened category.
Geographic Range
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).
Country Occurrence:
Native: French Guiana; Guyana; Suriname

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.).
Current Population Trend: Stable
Habitat and Ecology (see Appendix for additional information)
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.
Systems: Terrestrial
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 (see Appendix for additional information)
Its ranges overlaps with all of the protected areas in Suriname and French Guiana.
