Drosophila buzzatii has been found sympatric in Argentina with a closely-related sibling species, D. serido. The biogeographical, reproductive and chromosomal data allow us to combine these species into an evolutionary unit, the buzzatii cluster. Salivary gland chromosomes also have been used to determine their phylogenetic relationships with other closely related species, showing that the buzzatii cluster species share two inversions-2d(2) and 2s(6)-with the species of the martensis cluster. Both clusters arose from South American populations of the ancestor of the mulleri complex, and we propose to include D. buzzatii and D. serido in the mulleri complex of the repleta group.
在阿根廷,发现果蝇 buzzatii 与亲缘关系密切的姊妹种 D. serido 同域分布。生物地理、繁殖和染色体数据使我们能够将这些物种组合成一个进化单位,即 buzzatii 聚类。唾液腺染色体也被用来确定它们与其他密切相关物种的系统发育关系,表明 buzzatii 聚类物种与 martensis 聚类物种共享两个倒位-2d(2)和 2s(6)-。这两个聚类都是由 mulleri 复合体祖先的南美种群产生的,我们建议将 D. buzzatii 和 D. serido 纳入 repleta 组的 mulleri 复合体。
