This species occurs very sparsely in the humid Atlantic lowlands from eastern Nicaragua, through Costa Rica to central Panama, up to 600m asl. If it is a single species, it probably occurs more widely than current records suggest, especially in areas between known sites.
Habitat and Ecology
It inhabits humid lowland forest and presumably breeds by direct development.
This is a rare species with a wide range, with one specimen recorded from each of its known localities. There are no recent records from Costa Rica.
This species has most likely been affected by the destruction of its natural forest habitat for logging, agricultural development, livestock rearing, and human settlement.
Further research is required to resolve the taxonomic relationships between the specimens from the different known localities.
Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of continuing uncertainties as to its taxonomic status, extent of occurrence and ecological requirements.
It is not clear that the specimens from each of the recorded localities actually belong to the same species (David Wake pers. comm.).
