Drosophila populi species group

The Holarctic Drosophila populi species group belongs to the subgenus Sophophora and contains two species, Drosophila ingrica and Drosophila populi. D. ingrica is found in the Palearctic, while D. populi is found in the Nearctic. Both species are found in the northernmost subarctic forest zone, and are strongly associated with cotton wood.[1]

Sophophora

The paraphyletic subgenus Sophophora of the genus Drosophila was first described by Alfred Sturtevant in 1939.[1] It contains the best known drosophilid species, Drosophila melanogaster. Sophophora translates as carrier (phora) of wisdom (sophos). The subgenus is paraphyletic because the genus Lordiphosa[2][3] and the species Hirtodrosophila duncani[4][5] are also placed within this subgenus.

Drosophila melanogaster species group

The Drosophila melanogaster species group belongs to the subgenus Sophophora and contains 10 subgroups.[1][2] The phylogeny in this species group is poorly known despite many studies covering many of the species subgroups. The most likely explanation is that the various subgroups diverted from each other in a relative short evolutionary time frame. Three subgroups have not yet been investigated in molecular studies, and their position in the phylogeny is unclear. The suzukii subgroup is paraphyletic as D. lucipennis is systematically placed within the elegans subgroup.

Drosophila melanogaster species subgroup

The Drosophila melanogaster species subgroup contains 9 species, including the best known species Drosophila melanogaster and D. simulans. The subgroup belongs to the Drosophila melanogaster species group within the subgenus Sophophora.

Phylogeny[edit source | edit]




 D. (S.) melanogaster




 D. (S.) simulans



 D. (S.) mauritiana



 D. (S.) sechellia








 D. (S.) yakuba



 D. (S.) santomea




 D. (S.) teissieri





 D. (S.) orena



 D. (S.) erecta





melanogaster complex

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 branched off first and which second.
