This species formerly occurred in the interior uplands of Puerto Rico, at an altitude of 300-1,150 m asl.
Habitat and Ecology
A terrestrial species that breeds by direct development, it is known from extremely humid closed-canopy forest.
Formerly uncommon even in the 1980s, this species was last recorded in 1990 and subsequent extensive searches have failed to locate this species. It is now believed to be most probably extinct.
While the cause for this species' disappearance remains unknown, potential factors could have been climate change and disease. Rats and mongooses have also been suggested as potential threats (as invasive predators), although literature on this subject is equivocal (Hedges 1993, and Thurley and Bell 1994, support the notion that these introduced species comprise threats to amphibian species, while Reagan and Waide 1996, suggest that rats are lesser predators of Eleutherodactylus coqui), and there is currently no consensus regarding the impact that these species may or may not have on amphibian declines in Puerto Rico. Future research efforts directed at investigating the impact of these invasive species on amphibian populations may help to establish their relative contribution to amphibian declines.
This species was known to occur in Luquillo National Forest in the El Yunque area. In view of the risk of chytridiomycosis, it is a very high priority to conduct surveys to determine whether or not this species could still survive in the wild; surviving individuals might need to form the basis for the establishment of an ex-situ population.
