This species occurs between Cerro Pelón and Vista Hermosa in the Sierra de Juarez, north-central Oaxaca, Mexico, at an altitude of 2,400-3,000m asl.
Habitat and Ecology
The species is terrestrial and inhabits pristine moist forest habitats, and has been found under loose bark or fallen trees, or under moss on rocks and logs. It reproduces by direct development.
It used to be very common, but has undergone dramatic declines and is now uncommon. Only one individual has been located in recent years (c. 2000).
The major threat is habitat loss due primarily to logging, as well as agricultural expansion and human settlement. The reasons for the dramatic recent declines in this species require further investigation.
The type locality falls within a local conservation management area administered by the town of Santiago Comaltepec. This species is listed as "Threatened" (Amenazada) by the Mexican government.
