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.[1] Testacea species are specialist mushroom-feeding flies, and can metabolize toxic compounds in Amanita mushrooms.[2] 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.[3][4][5] Of note, selfish X chromosomes (a form of meiotic drive) have been discovered in three of the four Testacea group species.[6][7]
Testacea species are commonly found in association with members of the Drosophila Quinaria species group due to their shared mushroom-feeding life history.[8]
Systematics[]
The Testacea species group is a phylogenetically concise lineage consisting of 4 species. The closest outgroup of Testacea species is the Drosophila bizonata species group.[9][10]
