This species is known only from Zanatepec, Isthmus of Tehuantepec, in southern Oaxaca, Mexico, at 1,450-1,600m asl.
Habitat and Ecology
It inhabits pine-oak forest and breeds by direct development.
It is a very rare species.
The major threat is habitat disturbance and degradation due to logging and the creation of agricultural land. The area where this species occurs is still relatively undisturbed, due to the lack of roads and towns; however, logging is expected to increase in the next few years.
The range of this species does not include any protected areas, and there is an urgent need for protection of montane pine-oak forest habitat in this part of the state of Oaxaca. This species is protected by Mexican law under the "Special Protection" category (Pr).
Red List Status
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat in Oaxaca, Mexico.
This species was previously included in the genus Eleutherodactylus (Crawford and Smith 2005).
