This species is widely but patchily distributed in southern, central, and northern and north-western Hispaniola (both Haiti and Dominican Republic): Plaine du Nord-Valle de Cibao, Valle de San Juan, and Plaine du Cul de Sac-Valle de Neiba. The altitudinal range is from 40m below sea level up to 107m asl.
Habitat and Ecology
It occurs in dry lowland valleys, in both mesic and xeric areas, retreating under rocks and logs. Males call from rain-flooded areas, and eggs are laid in still water. The species breeds year round in some areas. It is occasionally found near water with heavy concentrations of sulphur.
In suitable habitats, this species can be found all year round. However, according to B. Hedges (pers. comm.) the species is infrequently encountered.
The major threats to this lowland species are habitat loss, due to both livestock grazing and selective logging, and agricultural pollution.
It occurs in several protected areas.
