The Drosophila immigrans species group is a polyphyletic and speciose lineage of Drosophila flies, including over 100 species. [1] [2] 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. [3] Immigrans group species are related to mushroom-breeding Drosophila of the Quinaria and Testacea species groups. [2] [4]
The Immigrans species group can be further divided into four subgroups: [2]
The Drosophilinae are the largest subfamily in the Drosophilidae. The other subfamily is the Steganinae.
The paraphyletic subgenus Sophophora of the genus Drosophila was first described by Alfred Sturtevant in 1939. It contains the best-known drosophilid species, Drosophila melanogaster. Sophophora translates as carrier (phora) of wisdom (sophos). The subgenus is paraphyletic because the genus Lordiphosa and the species Hirtodrosophila duncani are also placed within this subgenus.
The subgenus Dorsilopha belongs to genus Drosophila and consists of four species. The phylogenetic position of this group has been unclear for a long time, but recent studies have shown that the subgenus is positioned ancestral to the subgenus Drosophila.
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.
Drosophila is a paraphyletic subgenus of the genus Drosophila, a classification of fruit flies. This subgenus was first described by Alfred Sturtevant in 1939. Members of the subgenus Drosophila can be distinguished from other Drosophilid species by breaks in the pigmentation along the dorsal section of their abdomen.
Drosophila immigrans is a species of vinegar fly in the family Drosophilidae. Drosophila immigrans is a member of the Immigrans-tripunctata radiation of the subgenus Drosophila. It is related to the Drosophila quinaria and Drosophila testacea species groups, and the fellow Immigrans species group member Drosophila albomicans. Drosophila immigrans has been used in evolutionary studies to understand how viruses evolve with their hosts.
The Drosophila testacea species group belongs to the Immigrans-tripunctata radiation of the subgenus Drosophila, and contains 4 species: Drosophila putrida, Drosophila neotestacea, Drosophila testacea, and Drosophila orientacea. Testacea species are specialist mushroom-feeding flies, and can metabolize toxic compounds in Amanita mushrooms. The Testacea species group is studied for its specialist ecology, population genetics, and bacterial endosymbionts. The North American species Drosophila neotestacea is perhaps the best-studied of the group for its interactions with parasitic wasps and nematodes, bacterial endosymbionts, and trypanosomatid parasites. Of note, selfish X chromosomes have been discovered in three of the four Testacea group species.
The Drosophila quinaria species group is a speciose lineage of mushroom-feeding flies studied for their specialist ecology, their parasites, population genetics, and the evolution of immune systems. Quinaria species are part of the Drosophila subgenus.
Drosophila albomicans is a species of vinegar fly in the family Drosophilidae. Drosophila albomicans is a member of the Immigrans-tripunctata radiation of the subgenus Drosophila. The D. albomicans genome was first sequenced in 2012 to study the evolution of novel sex chromosomes, a characteristic this species is best known for. One commonly accepted definition of the biological species concept is that individuals or populations are members of different species if they are incapable of successful interbreeding. While D. albomicans and Drosophila nasuta are commonly referred to as distinct species, there appears to be little to no sexual isolation between these two Drosophila species. Instead, behavioural differences appear to reproductively isolate these two species.
The Drosophila guarani species group is a lineage of vinegar fly in the Immigrans-tripunctata radiation of the subgenus Drosophila first proposed by Dobzhansky & Pavan (1943). At least 24 species have been described, distributed throughout Latin America.
Zaprionus tuberculatus is a member of the subgenus and genus Zaprionus, family Drosophilidae, and order Diptera. It is an invasive fruit fly that originated in Africa, but can also be found in Europe and Asia. The fly earned its common name, the "vinegar fly", because researchers frequently captured the species using vinegar traps. Z. tuberculatus was previously considered a strictly tropical fly, but evidence of invasion to nontropical regions such as Turkey has been shown.
The Hawaiian Drosophilidae are a lineage of flies within the genus Drosophila. This monophyletic clade includes all of the endemic Hawaiian Drosophila and all members of the genus Scaptomyza, which contains both Hawaiian and non-Hawaiian species. The Hawaiian Drosophilidae are descended from a common ancestor estimated to have lived 25 million years ago. Species of Hawaiian Drosophilidae flies have been studied as models of speciation and behavioral evolution. Along with other members of the native Hawaiian ecosystem, the conservations status of many species of Hawaiian Drosophilidae is threatened by habitat loss and introduced predators, among other factors.
Drosophila albipalpis is a species of fly in the subgenus Dudaica.
Drosophila dissimilis is a species of fly in the subgenus Dudaica.
Drosophila gracilipalpis is a species of fly in the subgenus Dudaica.
Drosophila orthophallata is a species of fly in the subgenus Dudaica.
Drosophila qiongzhouensis is a species of fly in the subgenus Dudaica.
Drosophila malayana is a species of fly in the subgenus Dudaica.
The Drosophila robusta species group is a species group of fruit flies in the subgenus Drosophila.
The Drosophila virilis species group is a species group of fruit flies in the subgenus Drosophila.
