Habitat and Ecology [top]

Habitat and Ecology:This species is found under rocks and logs in pine and pine-oak forest. It is not known to what extent it might be able to adapt to degraded habitats.

Threats [top]

Major Threat(s): No threats have been identified. It is potentially at risk from the loss of its forest habitat, at least locally, if it is unable to adapt to secondary habitats.

Conservation Actions [top]

Conservation Actions: This is a poorly known species, and more fieldwork is needed to provide data on its natural history, on the status of its populations, and on its conservation requrements. It presumably occurs in a number of protected areas.
