This species is known only from the type locality (approximately 15° 53'N; 91° 16'W) on the northern slope of the Sierra de Cuchumatanes, Guatemala, at 1,050-1,080m asl.
Habitat and Ecology
It inhabits subtropical rainforest, breeding in temporary pools and slow-flowing streams, and also in the axils of elephant-ear plants. It can survive in heavily degraded habitats, providing that the habitat is not opened up too much.
It is rare and declining. Only 20 specimens have been collected and it is becoming harder to find.
The major threat is habitat loss due to human settlement (returning refugees), which is associated with expanding small-scale agriculture and wood collection. Chytridiomycosis also cannot be ruled out as a cause of the observed decline.
The species is not known to occur in any protected areas, and protection of its remaining intact habitat is recommended. Survey work is required to determine the current population status of this species.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered because its Extent of Occurrence is less than 100 km2, all individuals are in a single location, and there is continuing decline in the extent and quality of its habitat, and in the number of mature individuals in the Sierra de Cuchumatanes, Guatemala.
This species was previously included in the genus Hyla but has recently been moved to the resurrected genus Exerodonta (Faivovich et al. 2005).
