Drosophila immigrans species group

The Drosophila immigrans species group is a polyphyletic and speciose lineage of Drosophila flies, including over 100 species. Immigrans species belong to the Immigrans-tripunctata radiation of the subgenus Drosophila. Well-described species include Drosophila immigrans, and the sister species Drosophila albomicans and Drosophila nasuta. The genome of D. albomicans was sequenced in 2012 in an effort to characterize novel sex chromosome development in D. albomicans. Immigrans group species are related to mushroom-breeding Drosophila of the Quinaria and Testacea species groups.

Subgroups
The Immigrans species group can be further divided into four subgroups:


 * Immigrans subgroup: includes D. immigrans
 * Nasuta subgroup: includes D. albomicans and D. nasuta
 * Hypocausta subgroup
 * Quadrilineata subgroup
