This species is known only from the Sierra de las Minas and the Sierra de Xucaneb, central and eastern Guatemala, from 1,400-1,900m asl.
Habitat and Ecology
This species inhabits cloud forests, living in vegetation near cascading streams, and breeds in clear streams. It can survive in old secondary forest.
It is an uncommon species. There is evidence of a recent dramatic decline and possible extirpation in Río Cafetal, Baja Verapaz, Guatemala, in the Sierra de las Minas, possibly due to chytrid (a tadpole of another species at this site was confirmed to have chytridiomycosis).
The main threat is habitat loss, especially due to encroaching agriculture (in particular leather-leaf plantations). There is also the risk of contamination or change in flow-regime of streams. As noted, chytridiomycosis is also a threat, given the impact that it has had on some other members of this genus in Central America, and due to the apparent disappearance of this species at a site where chytridiomycosis in another species has been confirmed.
It occurs in the Reserva de la Biósfera Sierra de las Minas and Biotopo del Quetzal. In view of the threat of chytrid, the status of this species should be very 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 a ten year period including the past, due to continuing decline in the extent and quality of its habitat, and the potential impact of chytridiomycosis.
