This species has a very restricted distribution in the Sierra del Luquillo, Puerto Rico. Its altitudinal range is from 660-1,039m asl.
Habitat and Ecology
It lives underground in elfin forest, and males call from root cavities of various trees. It has not been recorded outside forest.
The population of this species is currently believed to be stable.
Although the population is currently stable, and there are no immediate major threats to the habitat of this species, its very restricted range and specialized habits make it vulnerable to extinction even in the protected areas of El Yunque through stochastic and/or global processes, which may include climate change and/or chytridiomycosis.
It occurs in the Luquillo National Forest. In view of the possible risk of disease to this species, the status of this species should be closely monitored, and it might be necessary to establish ex-situ assurance colonies.
Red List Status
Listed as Vulnerable because its area of occupancy is less than 20 km2, making is susceptible to stochastic and global processes.
