Major Threat(s): The removal of the forest habitat from above the caves has caused the caves to dry out, resulting in the apparent disappearance of this species.

Conservation Actions [top]

Conservation Actions: It is not known from any protected area. A survey is needed to evaluate the status of this species, and protection of the original habitat (both of the caves and the surrounding forest) is urgent. This species is protected by Mexican law under the "Special Protection" category (Pr).
