This species is known from the slopes of the Tacana volcano in Chiapas, Mexico, and from the mountains along the south-western Guatemalan Plateau (in particular the Atitlán, Tajumulco and Tacana volcanoes). Its altitudinal range is 1,800-2,200m asl.
Habitat and Ecology
It occurs on mountain slopes covered by pine-oak and cloud forests, living in the vegetation, and under the bark of logs, rarely in bromeliads; it is not commonly found on the ground, and does not occur in disturbed habitats. Breeding is by direct development, and the species is not dependent upon water.
It appears to have always been a relatively uncommon species.
The main threat is the loss of forest habitat due to agricultural expansion, logging, and conversion to urban lands, activities that have been very severe throughout its range.
It might be found in the Biosphere Reserve of La Encrucijada, Chiapas, Mexico, but is not otherwise known from any protected area. In Guatemala there is a small reserve of cloud forest in San Marcos. The Instituto de Historia Natural of Chiapas is conducting a conservation project in this area. This species is protected by Mexican law under the "Special Protection" category (Pr).
Red List Status
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat along the Pacific versant of Guatemala and Mexico.
