Résumé |
To determine the species diversity of cichlids in the Banc d'Arguin National Park (PNBA) and their phylogenetic relationships with other species in West Africa, a morphometric and meristic and molecular phylogenetic study was conducted. Both approaches not only confirm the presence of Sarotherodon melanotheron in PNBA but also demonstrate the presence of a second species from the genus Coptodon. While morphometric characteristics match the description of the Guinean tilapia Coptodon guineensis, phylogenetic reconstructions based on three mitochondrial and one nuclear DNA fragment demonstrate that C. guineensis is paraphyletic over its range. Because different lineages of C. guineensis are allopatric, the distribution of C. guineensis should be restricted to Ghana and Cote d'Ivoire. The many other lineages of this species should be considered as C. sp. aff. guineensis. (C) 2016 The Fisheries Society of the British Isles |
