Isthmohyla melacaena is known to occur in El Cusuco National Park, 15 31' N, 88 12' W, 1370–1990 m elevation, Department of Cortes, Honduras, and "mountains west of San Pedro, Honduras"’ (see McCranie and Castañeda, 2007).
Habitat and Ecology
The species is known from 1370 to 1990 m elevation in pine forest with an understory of broad leaf shrubs and grasses and in broadleaf cloud forest. Many bromeliads occur on the pine trees at the type locality, which lies on a hillside at least 150 m from the nearest streams or rivers (McCranie and Castañeda, 2006). The other known specimens were also probably associated with bromeliads. Tadpoles have also been collected in bromeliads (J.R. McCranie and F. Castañeda, pers. comm. 2008).
Males call at night from 1-2 m above the ground, a female was found at ca 3 m above the ground. The species appears to retreat into bromeliads (3-5 m high) during the daytime. Bromeliohyla bromeliacia was found in sympatry with I. melacaena (McCranie and Castañeda, 2006).
This is considered to be a common species (J.R. McCranie, pers. comm. 2008).
Habitat destruction outside of El Cusuco National Park (J.R. McCranie, pers. comm. 2008).
The species occurs within the confines of El Cusuco National Park.
Isthmohyla melacaena is diagnosed from other small Middle American hylids by a combination of morphological features (McCranie and Castañeda, 2006).
