This species is known from the Sierra de Juárez, east of Oaxaca City, in south-eastern Mexico, at 2,640-2,890m asl.
Habitat and Ecology
This species is associated exclusively with pristine streams in cloud forests.
This has always been a rare species, but it appears to have gone into serious decline, and has not been recorded since 1984. Recent surveys to locate it have been unsuccessful, and it might now be extinct.
This species has disappeared in suitable habitat, probably due to chytridiomycosis. The fragmentation and disturbance of the forest due to logging and other human activities, and the continuing desiccation of streams, has probably also contributed to the disappearance of this species.
The range of this species is not within any protected area. Urgent restoration and protection of the remnants of cloud forest in the Sierra de Juárez is required. A field study is necessary to evaluate the population status of this species, and whether or not it still survives in the wild. In view of the threat of chytridiomycosis, surviving individuals might need to form the basis for the establishment of an ex-situ population.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered because its Area Of Occupancy is less than 10km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat, and in the number of mature individuals, in Oaxaca, Mexico.
This species was previously included in the genus Hyla but has recently been moved to the genus Plectrohyla (Faivovich et al. 2005).
