This species is known only from Vista Hermosa town, Sierra de Juárez, north-central Oaxaca, Mexico, at about 1,500m asl.
Habitat and Ecology
This species inhabits cloud forest; it appears to have arboreal habits and breeds by direct development.
This has always been a rare species, but it appears to have gone into serious decline, and has not been recorded since 1983. Recent surveys to locate it have been unsuccessful, and it might now be extinct.
Although disturbance and clear cutting of montane cloud forest habitats in Sierra de Juárez (primarily for agriculture) represent a threat to this species, it has disappeared even in suitable habitat, probably due to chytridiomycosis.
This species is an urgent priority for survey work in order to determine whether or not it still survives in the wild, and any surviving populations might need to be maintained in captivity if the risk of chytridiomycosis proves genuine. The range of this species does not include any protected areas, and protection and restoration of the remaining cloud forest is urgently needed in the Sierra de Juárez where no protected areas currently exist. This species is protected by Mexican law under the "Special Protection" category (Pr).
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered because of a drastic population decline, estimated to be more than 80% over the last three generations, inferred from the apparent disappearance of most, or all, of the population, probably due to chytridiomycosis.
This species was previously included in the genus Eleutherodactylus (Crawford and Smith 2005).
