This species is known only from the Coscomatepec region in central Veracruz, Mexico, at altitudes of 900-1,500m asl.
Habitat and Ecology
It is highly associated with epiphytic plants in cloud forest, but breeds in temporary streams.
It is a rare species.
The major threat is habitat loss due to the conversion of original forest cover to agricultural land, especially coffee plantations.
The range of this species is not within any protected area, and protection and restoration of cloud forest remnants is extremely urgent. Survey work is necessary to establish its current population status. It is listed as "Threatened" (Amenazada) by the Mexican government.
This species was previously included in the genus Hyla but has recently been moved to the new genus Megastomatohyla (Faivovich et al. 2005).
