The unique biodiversity in the Red Sea is the result of complex ecological and evolutionary processes driven by Pleistocene climatic change. Here we investigate the species diversity, phylogenetic relationships and phylogeographical patterns of giant clams in the Western Indian Ocean (WIO) and the Red Sea to explore scenarios of marine speciation in this under-studied region.

Acknowledgements: We are grateful to Boris Sirenko for access to the type mate-rial of T. rosewateri at the Zoological Institute of the Russian Academy of Sciences in St Petersburg and allowing us to sample dried muscle tissue, to Antonio Bonfitto (University of Bologna, Italy) for kindly providing part of the dry ligament and photo-graphs of the lectotype of T. elongatissima and to Gustav Paulay for sharing T. squamosina sample UF463401 from the Farasan Island, Saudi Arabia. We would like to thank Claude Payri, Thierry Hoareau and Francesca Benzoni for insightful discus-sions, and Gustav Paulay and two anonymous referees for their constructive comments on earlier versions of the manuscript. Relevant fieldwork permission was obtained for all sampling lo-cations. Sampling in the North-West of Madagascar (CF, HM, SA) was done during the MAD ( oceanographic campaign on board of RV Antea(IRD). Sampling in Reunion Island (HM, PG) was supported by program TriMax (LabEx CORAIL fund); in the South of Madagascar (HM) in collaboration with the Institut Halieutique et des Sciences Marines, University of Toliara (IH.SM); in Juan de Nova (HM) by program BIORECIE (financial supports from INEE, INSU, IRD, AAMP, FRB, TAAF, and the foundation Veolia Environnement); The Atimo Vatae expedition to South Madagascar (Principal Investigator, Philippe Bouchet) was part of a cluster of Mozambique-Madagascar expeditions funded by the Total Foundation, Prince Albert II of Monaco Foundation, Stavros Niarchos Foundation, and additional support from the Richard Lounsbery Foundation and Triballat, under ‘Our Planet Reviewed', a joint initiative of Muséum National d'Histoire Naturelle (MNHN) and Pro Natura International (PNI) in part-nership with IH.SM and the Madagascar bureau of Wildlife Conservation Society (WCS). Sampling in the Red Sea (THS) was supported by Eric Mason of Dream Divers, and the captain and crew of the MV Dream Master. This is ENTROPIE contribution no 413.
