Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(i,ii,iii)+2ab(i,ii,iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
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)
Justification:
This is an undescribed species with voucher specimens held at the American Museum of Natural History and University of Michigan Museum of Zoology. This species remains abundant in the Nosivolo, a major tributary of the Mangoro River and is also present in the main channel of the Mangoro for a distance of several kilometers up and downstream of the town of Marolambo. Pending major shifts in land use in the basin, this species is assessed as Vulnerable on the grounds that its extent of occurrence and area of occupancy are less than 20,000 km² and less than 2,000 km², respectively, and a continuing decline in distribution range due to the impact of introduced, competing and predatory exotic species.
