This species has a patchy distribution in the interior uplands of Puerto Rico at an altitudinal range of 40-1,152m asl.
Habitat and Ecology
It is terrestrial in mesic forests. Males call from the ground or low vegetation. Eggs are laid in rotten logs, and develop directly.
There has been an unexplained decline of this species during the last two decades.
The cause of the decline in this species is not known, but it is thought that chytridiomycosis linked with climate change might have played a role.
It is known to occur in several protected areas. Further research and survey work is needed to determine the reasons for the decline, and the species' current population status. In view of the possible risk of chytridiomycosis, surviving individuals might need to form the basis for the establishment of an ex-situ population.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered because of a projected decline in both number of mature individuals and area of occupancy, estimated to be more than 80% over the next ten years, perhaps due to chytridiomycosis and the effects of climate change.
