From the IUCN Red List Species Account:


Range Description

This species is known only from the road to La Cumbre, Municipio de la Democracia, Huehuetenango, Guatemala, from approximately 600-1,000m asl.

Habitat and Ecology

It occurs along, and reproduces in, streams in dry forest.


It was found to be common in 1996 within this restricted range.

Population Trend


Major Threats

Although this species does tolerate moderate levels of habitat destruction, wholesale habitat loss caused by agricultural activities is a major threat to the species. Chytridiomycosis is also a major threat, and declines due to the disease have already been detected amongst species of this genus in Guatemala (Mendelson et al. 2004).

Conservation Actions

It is not known to occur in any protected areas, and habitat protection is urgently needed. In view of the severe risk of chytridiomycosis, the status of this species should be closely monitored, and ex-situ populations might need to be established.

Red List Status

Critically Endangered (CR)


Listed as Critically Endangered because its Extent of Occurrence is less than 100km2, all individuals are in a single location, and there is continuing decline in the extent and quality of its habitat in Guatemala.

Taxonomic Notes

This species was removed from synonymy of Ptychohyla euthysanota by Campbell and Smith (1992).
