Assessor(s): Loiselle, P. & participants of the CBSG/ANGAP CAMP "Faune de Madagascar" workshop, Mantasoa, Madagascar 2001

This species has only been found in one tributary of the Faraony River, whose watershed has been almost entirely stripped of forest cover. This species must also cope with an exotic predator, the spotted snakehead. The species is assessed as Critically Endangered on account of its highly restricted distribution (extent of occurrence and area of occupancy of less than 100 km² and 10 km² respectively), combined with a continued loss of habitat and predation/competition from an invasive species.
