All three of the species listed are in the subgenus Sophophora, the same subgenus containing D. melanogaster. During the Sophophora radiation, the groups that contain all these species diverged from each other, sometime between 53 and 46 million years ago (according to source reproduced on pg 1111 of Ashburners Drosophila lab manual). D. saltans is in the saltans group, willistoni in the willistoni group, and pseudoobscura in the obscura group. There are extensive references in the Ashburner book that might be of further help, including a phylogenetic radiation tree of the genus Drosophila, including the major subgenera and groups. Jim .
