DistributionRead full entry
Range DescriptionThis species is restricted to the forested areas of central and eastern Tobago Island, Trinidad and Tobago. It is found at elevations of between 30 and 490 m asl, its distribution is determined by the presence of suitable streams (Alemu I et al. in prep.). Its range, taken as a proxy for extent of occurrence (EOO), is estimated to be 151 km2, although the area of occupancy (AOO), while not calculated, would be considerably smaller, as it is restricted to streams. Murphy (1997) reported this frog from Little Tobago, a 1 km2 island 2.4 km off the east end of Tobago, and this information was included in this species' previous (2004) assessment. However, the habitats of Little Tobago differ from the rainforest habitats of northeastern Tobago, and Little Tobago has no permanent streams or sources of ground water, since all the fresh water on the island comes from rainfall, which is quickly absorbed by the soil (Beard 1944, J. Alemu I pers. obs.). Given that this species is associated with streams, Murphy’s (1997) record from Little Tobago is probably erroneous. Charles et al. (2011) do not mention this species as occurring on Little Tobago.
