This species occurs in two sites in southern Veracruz, Mexico: the peak of Cerro Chicahuaxtla, Cuatlalpan, at 1,600m asl; and at 1,200-1,300m asl on Volcán San Martín. It is likely that the taxon consists of two separate species, one in each site.
Habitat and Ecology
It is arboreal in montane tropical forest (cloud forest) living in bromeliads, an unusual habitat for a salamander in this genus. It reproduces by direct development.
Once relatively common, it is now very rare; a single specimen was recorded at Cerro Chicahuaxtla in 2007 after not having been seen since the mid-1980s.
Most of the habitat of this species has disappeared or has been severely degraded as a result of logging, agriculture, and expanding human settlements.
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).
Red List Status
Critically Endangered (CR)
It is likely that this form consists of two separate species (G. Parra-Olea and D. Wake pers. comm.).
