From the IUCN Red List Species Account:


Range Description

This species is known from humid lowlands and premontane slopes from Departamento Gracias a Dios in Honduras (McCranie et al., 2003) and south-eastern Nicaragua to south-eastern Costa Rica on the Atlantic versant (20-900m asl), and on the Pacific versant in humid premontane areas of south-western Costa Rica and western and central Panama, at 1,000-1,330m asl (Savage, 2002). It is expected to have a wider distribution than is currently known.

Habitat and Ecology

This is a nocturnal canopy species of primary humid lowland and montane forest. Eggs are deposited in tree holes, which is also where the larvae develop. Males have been found calling from tree holes (McCranie et al., 2003).


There is no information on the population status of this rarely seen, high-canopy species.

Population Trend


Major Threats

The major threat is loss of primary forest habitat due to agricultural expansion, logging, and human settlement.

Conservation Actions

The species has been recorded from several protected areas in both Panama and Costa Rica. Further surveys are required to fully determine the range of this species.

Taxonomic Notes

This species was previously included in the genus Hyla but has recently been moved to the new genus Ecnomiohyla (Faivovich et al. 2005). We follow Duellman (2001) and Savage (2002) in assigning records from Colombia and Ecuador to Ecnomiohyla phantasmagoria.

Ecnomiohyla miliaria is currently a species complex which is under revision (Brian Kubicki pers. comm.).
