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.
