Red List Category & Criteria:

Endangered B1ab(i,iii) ver 3.1

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)

Justification:
Rheocles wrightae was previously assessed as Critically Endangered. Improved information since then has resulte in the species being downgraded to Endangered.

This species has been collected from two tributaries of the Mangoro River, Madagascar. With a restricted range (EOO < 5,000 km²), fragmentation and continued decline of habitat extent/quality through the impacts of deforestation, and threats from introduced exotic species, this species is assessed as Endangered.

History:

1996	–	Critically Endangered
1994	–	Endangered (Groombridge 1994)
