This species is known only from the type locality, Icacos Swamp on the south-western peninsula of Trinidad Island, Trinidad and Tobago.
Habitat and Ecology
A specimen of this species was found calling at night in a burrow under a mass of fern roots in a stagnant swamp. It is presumed to use aquatic habitats for breeding and to breed by larval development.
The current population status of this species is not known. Since the species was described, extensive surveys of the type locality have not located any further specimens.
There are no known threats at present; the Icacos Swamp is a relatively pristine area.
Since it currently has no formal protection, consideration should be given to establishing Icacos Swamp as a protected area. There remains a need for further surveys at appropriate times of the year at the type locality to determine whether or not this species still persists.
Red List Status
Listed as Vulnerable because it is known from only a single location.
