Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): 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.

Conservation Actions [top]

Conservation Actions: 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).
