The immigrans-tripunctata radiation is a speciose lineage of Drosophila flies, including over 300 species. The immigrans-tripunctata radiation is a sister lineage to most other members of the subgenus Drosophila. A number of species have had their genomes or transcriptomes sequenced for evolutionary studies using Drosophila.
The following species groups and numbers largely derive from O'Grady (2018).
The following species have extensive genetic sequence data available as of August 2019.
Quinaria species group
Immigrans species group
Testacea species group
Work published in 2021 and 2024 has greatly expanded the coverage of genomes in this group with 18 new genomes in 2024. The 2024 work presents the first genomes for the tripunctata, testacea, and funebris groups.
