Assessor(s): Loiselle, P. & participants of the CBSG/ANGAP CAMP "Faune de Madagascar" workshop, Mantasoa, Madagascar 2001
Reviewer(s): Stiassny, M.L.J., Sparks, J.S. (AMNH, New York) & Darwall, W (Freshwater Biodiversity Assessment Programme)
Assessed as Near Threatened because it almost qualifies for Vulnerable under criterion B (VU B1ab(i,ii,iii)+2ab(i,ii,iii)). It only fails to qualify because it is found in marginally more locations (recorded at 11 locations) than the maximum of 10 required under VU criterion B. It is known from a number of Madagascar's east coast rivers and lakes, in the region between Ivoloina and Mangoro. The habitat is fragmented and continues to be heavily impacted by siltation and flow changes due to deforestation.
