Abstract
Ptychochromoides itasy Sparks, 2004, known locally in Madagascar as the trondro mainty or marakely à bosse, a robustjet black cichlid with a pronounced nuchal hump in both sexes, had not been collected in the wild for several decades andwas presumed to be extinct. Recently, a relict population of P. itasy was discovered in a tributary of the Tsiribihina Riverin the central highlands, to the west of the capital, Antananarivo. We report on the rediscovery, and present DNA sequenceevidence to both confirm the identity of the species as a member of Ptychochromoides and to resolve the placement of P. itasy within the genus.References
