Pelusios seychellensis  is thought to be a freshwater turtle species endemic to the island of Mahé, Seychelles. There are only three museum specimens from the late 19 th  century known. The species has been never found again, despite intensive searches on Mahé. Therefore,  P. seychellensis  has been declared as “Extinct” by the IUCN and is the sole putatively extinct freshwater turtle species. Using DNA sequences of three mitochondrial genes of the historical type specimen and phylogenetic analyses including all other species of the genus, we provide evidence that the description of  P. seychellensis  was erroneously based on a widely distributed West African species,  P. castaneus . Consequently, we synonymize the two species and delete  P. seychellensis  from the list of extinct chelonian species and from the faunal list of the Seychelles.
