This species occurs only in the Sierra de Los Tuxtlas and a few other localities near the Santa Marta volcano, in southern Veracruz, Mexico. It is known from 200-1,600m asl.
Habitat and Ecology
It inhabits tropical pine-oak forests with abundant leaf-litter. It is a stream-breeding amphibian.
This is a naturally rare species.
The major threat to this species is loss and degradation of its pine-oak forest habitat due to agricultural activities (crops and livestock), wood extraction, and infrastructure development.
Although this species can be found in protected areas, the protection of these areas is not always guaranteed, and some are subject to human disturbance; improved management of these is urgently needed. This species is protected by Mexican law under the "Special Protection" category (Pr).
