This species is known only from two localities in Cerro Tres Picos and Soconusco region, south-western Chiapas, Mexico. It is known from elevations at around 2,130m asl.
Habitat and Ecology
It is a stream-breeding amphibian that inhabits cloud forest at high elevations.
It is considered rare.
Transformation or deforestation of the cloud forests in the Soconusco region is a major threat to this species. Chytridiomycosis may also be a threat, as it is a high-elevation stream dweller, and declines due to the disease have already been detected amongst other species of this genus.
The range of this species includes the Reserva de la Biósfera La Sepultura, which still contains well-preserved forest areas. Regular surveillance of this area is required to avoid illegal logging and other human activities from degrading the forest. Protection of other forest areas in Chiapas is needed. Further survey work is needed to better understand the population status of this species, and whether chytrid poses a threat. This species is protected by Mexican law under the "Special Protection" category (Pr).
Red List Status
Listed as Endangered, in view of its extent of occurrence of less than 5,000km2 and area of occupancy of less than 500km2, with all individuals in fewer than five locations, and a continuing decline in the extent and quality of its habitat in Chiapas, Mexico.
