Scientific Name:	Ptychochromis sp. nov. 'Kotro'
Species Authority:
Taxonomic Notes:	Voucher specimens held at MNHN.

Assessment Information [top]

Red List Category & Criteria:	Extinct ver 3.1
Year Published:	2004
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 MNHN. It has not been collected for many years despite targeted efforts within its former range. Five preserved specimens represent the only known material collected from the Onilahy River in 1962. The main impacts thought to have caused the decline of this species are deforestation leading to loss of habitat through increased sedimentation, competition from introduced tilapias and overfishing. This species is assessed as Extinct.
