Threats [top]

Major Threat(s): Most of the habitat of this species has disappeared or has been severely degraded as a result of logging, agriculture, and expanding human settlements.

Conservation Actions [top]

Conservation Actions: It is not known from any protected areas, and protection of the remaining habitat at the two known sites is urgently needed. Survey work is also needed to ascertain whether or not the species survives in the wild at either site. This species is protected by Mexican law under the "Special Protection" category (Pr).
