This species has a relatively wide distribution in the Sierra de Juarez and the mountains above Totontepec, north-central Oaxaca, Mexico, at 2,300-3,000m asl.
Habitat and Ecology
It is a terrestrial species that inhabits pine-oak forests. It also occurs in degraded habitats. It reproduces by direct development.
It was formerly very abundant, but underwent major declines since the 1970s, and is now uncommon.
There is some forest loss in its range due to clear-cutting and livestock grazing.
It has not been recorded in any protected areas, and there is an urgent need for the protection of pine-oak forest habitat in the Sierra de Juarez. This species is protected by Mexican law under the "Special Protection" category (Pr).
