“Drosophila saltans species group”的意思、由来-开放百科全书

The Drosophila saltans species group contains 21 described fly species, all of which are found in the neotropical region. It is one of the seven species groups in the subgenus Sophophora, the others being willistoni, melanogaster, obscura, dispar, fima, and dentissima. The saltans species group is most closely related to the willistoni subgroup. The species are placed into five subgroups: cordata, elliptica, parasaltans, saltans, and sturtevanti. It is thought that, like the willistoni species group, the saltans species group originated in tropical North America, colonized South America, and then diversified prior to the formation of the Isthmus of Panama. Some of these may have migrated back to North America within the last 4.5 million years ago (mya), and consequently the relationship between the species is unresolved due to the short amount of time that has elapsed since their divergence points.^[1]^[2]^[3]
