This species is found in the extreme west of the Sierra Nombre de Dios, La Fortuna village, between the Departamentos of Yoro and Atlantica, north-central Honduras. The type locality is at 1,550m asl.
Habitat and Ecology
This species is found on the ground and on low vegetation along streams, in lower montane wet forest. It lays its eggs in patches of moss in trees overhanging streams; when the eggs hatch the tadpoles fall in to the stream.
This species is moderately common within its very restricted range.
The major threat to this species is habitat loss due to agriculture and logging. This frog is very dependent on pristine habitat as it depends on sufficient humidity for moss for breeding in the trees.
The range of this species is known to be within Texiguat Wildlife Refuge. Maintenance of existing tracts of remaining habitat is an important conservation measure for this species.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered because its Extent of Occurrence is less than 100 km2 and its Area Of Occupancy is less than 10km2, all individuals are in a single location, and there is continuing decline in the extent and quality of its habitat in north-central Honduras.
This species was previously included in the genus Hyla but has recently been moved to the new genus Isthmohyla (Faivovich et al. 2005).
