This species is known only from caves in the Reserve de la Biósfera El Cielo in Tamaulipas in north-eastern Mexico, at about 1,050-1,800m asl.
Habitat and Ecology
It is a cave-dwelling species. It breeds by direct development and is not dependent upon water.
It was formerly fairly common. It was last seen in the mid-1980s, and one search in the late 1990s did not locate it. It is not known whether or not it has declined, or whether or not the lack of records is a reflection of the lack of observer effort.
This species would be at risk if there is disturbance of its cave micro-habitat, where it presumably relies on high humidity levels. However, the area where it occurs is currently well protected.
It occurs in the Reserve de la Biósfera Rancho El Cielo which is quite well protected. There is a need for close monitoring of the population status of this species. This species is protected by Mexican law under the "Special Protection" category (Pr).
