Phylogeny of the Drosophila melanogaster subgroup

melanogaster complex D. (S.) melanogaster Meigen, 1830 simulans complex D. (S.) simulans Sturtevant, 1919 D. (S.) mauritiana Tsacas and David, 1974 D. (S.) sechellia Tsacas and Bächli, 1981 yakuba complex D. (S.) yakuba Burla, 1954 D. (S.) santomea Lachaise and Harry, 2000 D. (S.) teissieri Tsacas, 1971 erecta complex D. (S.) erecta Tsacas and Lachaise, 1974 D. (S.) orena Tsacas and David, 1978

The species of the simulans complex form a hard polytomy. Most likely, the island species D. (S.) mauritiana (Mauritius) and D. (S.) sechellia (Seychelles) branched of from the mainland species D. (S.) simulans in such a narrow time frame that it is impossible to distinguish which species brached off first and which second.
