Scientific classification OOjs UI icon edit-ltr.svg

Family: Drosophilidae
Genus: Drosophila
Species group: melanogaster
Species subgroup: melanogaster

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

Males can discriminate between females of different species, in part, by detecting differences in the hydrocarbon pheromones coating their bodies. [1] Females can discriminate between males of different species, in part, by detecting species-specific differences in the male's courtship behavior. [2] When copulation does occur between different species, the hybrid progeny are often non-viable, sterile or fertile with lower fitness.

Phylogeny

The phylogeny of the melanogaster complex

simulans complex

yakuba complex [3] [4]

erecta complex

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 off 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.
