This species is known only from Agua del Obispo at 980m asl, central Guerrero, Mexico, although it is likely to occur a little more widely.
Habitat and Ecology
It has been recorded inhabiting pine-oak forests, 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 1984. Recent surveys to locate it have been unsuccessful, and it might now be extinct.
Loss of original forest cover due to conversion to agricultural land, and as a result of excessive logging, has had an impact of this species. However, it has also disappeared in suitable habitat, probably due to chytridiomycosis.
This species is a priority for further survey work to determine whether or not it might still survive in the wild, and surviving populations might need to form the basis for a captive-breeding programme. The range of this species does not include any protected areas, and protection of the Agua del Obispo forests is urgent since there are many threatened amphibians known to occur in this area. It 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).
