This species occurs in two disjunct populations on the Atlantic slopes of northern Chiapas, Mexico, and western Guatemala. Its altitudinal range is from 1,175-2,200m asl. Its distribution remains largely unknown, and the species could occur more widely.
Habitat and Ecology
The species occurs in montane cloud forests, and is associated with high-elevation streams and adjacent low vegetation where it also breeds.
There is no information on its population status in Guatemala, but they are considered rare in Chiapas.
The disturbance and deforestation due to human settlement and associated activities is a major threat. Chytridiomycosis is also a threat to this species, since it is a high-elevation stream-dweller, and declines due to the disease have already been detected amongst other species of this genus.
The species is not known to occur in any protected areas, and protection of the remaining forests in Chiapas, in particular, is urgent. In view of the threat of chytridiomycosis, the status of this species should be closely monitored, and ex-situ populations should be established.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered because of a projected population decline, estimated to be more than 80% over the next ten years, due to continuing decline in the extent and quality of its habitat, and the potential impact of chytridiomycosis.
