From the IUCN Red List Species Account:


Range Description

This species is known only from the vicinity of the type locality at around 2,150m asl on the mountain pass of Plan de Guadalupe in the Sierra de Mazateca of northern Oaxaca, Mexico. Future work might prove it to be more widespread than current records suggest.

Habitat and Ecology

The natural habitat of this species may be cloud forest, consisting mainly of oaks, but the area around the type locality has almost completely been deforested. The fact that individuals were found in such altered habitat might indicate that it has a great tolerance of habitat degradation, but it is unclear for how long it can tolerate such degradation. Individuals were found under small rocks and schist slabs in roadside talus. This species is presumed to reproduce by direct development.


It is only known from a total of five individuals collected on two separate trips at two adjacent localities (within 5km of each other).

Population Trend


Major Threats

It is threatened by the significant deforestation caused by uncontrolled logging around the type locality.

Conservation Actions

This species is not known from any protected areas. Further studies are needed to better determine the species range, and the threats to it.
