This species is known only from near Ayutla, east-central Oaxaca, Mexico, at 2,100m asl.
Habitat and Ecology
It is a terrestrial inhabitat of pine-oak forest and madroño (arbutus forest). It can tolerate some habitat disturbance, as evidenced by the fact that a handful of small populations survive in several tiny fragments of remaining habitat. It breeds by direct development and is not dependent upon water.
It is an uncommon species.
The major threat to this species is the extensive loss of habitat that has taken place due to agriculture, logging and human settlement, and only small fragments of original habitat remain.
It is not known from any protected areas, and there is an urgent need for the protection of forested areas near Ayutla. This species is listed as "threatened" (Amenazada) by Mexican law.
