This species occurs on the slopes of the Cordillera de Tilarán, Cordillera Central, and Cordillera de Talamanca of Costa Rica and western Panama, from 750-1,900m asl (Savage 2002). It almost certainly occurs more widely than has been mapped, and is also probably found between known sites.
Habitat and Ecology
This is a nocturnal canopy species associated with primary humid premontane and lower montane forest. Breeding, egg deposition and larval development take place within tree-holes.
Because this is a high-canopy species, it is overlooked, and it is therefore hard to assess its population status.
The main threat is general habitat loss as a result of deforestation due primarily to the clearing of land for livestock ranching.
The species has been recorded from Parque Internacional La Amistad, Panama, and in more than three protected areas within Costa Rica.
This species was previously included in the genus Hyla but has recently been moved to the new genus Ecnomiohyla (Faivovich et al. 2005).
