This species is widely, albeit patchily, distributed in Hispaniola (Haiti and Dominican Republic), with an altitudinal range from sea level up to 900m asl.
Habitat and Ecology
It occurs in xeric pine forest and mesic forest, including in degraded areas. Males call from, and females lay eggs in, closed underground chambers. Breeding is by direct development.
It is rarely encountered, and believed to be declining in suitable habitat for reasons that are unknown.
The major threat is severe habitat destruction due to agriculture (the cultivation of crops and livestock farming) and charcoaling. However, this does not explain the decline in suitable habitats, and other factors such as invasive predators, climate change, and chytridiomycosis may be implicated.
It occurs in several protected areas. Further research is necessary to investigate the reasons for the decline of this species in suitable habitat. Further, given that this may represent a complex of species, each with an exceedingly small range, taxonomic work is needed to ascertain the true taxonomic status of individual populations.
Red List Status
Listed as Endangered because its Extent of Occurrence is probably less than 5,000km2, its distribution is severely fragmented, and the extent of its forest habitat, and the number of mature individuals, on Hispaniola is declining.
This species is probably a complex of several species.
