Drosophila obscura物种组的物种（例如，D. pseudobscura、拟暗纹叶蝉D. subobscura）自20世纪30年代以来一直是进化研究中的有利模型。尽管进行了大量的研究与不同类型的数据，在这个组的基础性生殖仍然是有争议的，大概是由于不仅假设的“快速辐射”的历史，这一组，但也有限的分类群采样从旧大陆（特别是东方和非洲热带地区）。在这里，我们重建了这一组的21个物种（包括16个旧世界的），覆盖所有6个亚组的6个位点的序列数据，估计谱系之间的分歧时间，并统计检验的“快速辐射”的假说。系统发育分析表明，每一个subobscura，sinobscura，affinis和pseudobscura亚群是单系的。subobscura和microlabis亚群形成obscura组中的基部分支。obscura亚组的部分种（D. ambigua D. obscura/暗纹叶蝉D. tristis三和弦加上D. subsilvestris/D. dianensispair）形成一个单系群，似乎与sinobscura亚群关系最密切。其余的基础关系，在暗箱组没有解决本研究。基于线粒体DNA数据的ML树上的分歧时间估计与30-35万年的校准之间的分歧obscura和黑腹类。研究结果表明，目前的主要支系中至少有一半起源于中新世中期（约15 Mya），这是北半球温带森林最后一次发展和破碎的时期。在入侵新大陆之前，暗箱组织开始迅速多样化。subobscura和microlabis亚群形成了这个组的基础分支。obscura亚群为并系群。该亚群的部分成员（D. ambigua，拟水螅D. obscura，黑腹拟步行虫D. tristis、黑腹叶蝉D. subsilvestris和D. dianensis）形成一个单系群，似乎与sinobscura亚群关系最密切。
Species of the Drosophila obscura species group (e.g., D. pseudoobscura, D. subobscura) have served as favorable models in evolutionary studies since the 1930's. Despite numbers of studies conducted with varied types of data, the basal phylogeny in this group is still controversial, presumably owing to not only the hypothetical 'rapid radiation' history of this group, but also limited taxon sampling from the Old World (esp. the Oriental and Afrotropical regions). Here we reconstruct the phylogeny of this group by using sequence data from 6 loci of 21 species (including 16 Old World ones) covering all the 6 subgroups of this group, estimate the divergence times among lineages, and statistically test the 'rapid radiation' hypothesis. Phylogenetic analyses indicate that each of the subobscura, sinobscura, affinis, and pseudoobscura subgroups is monophyletic. The subobscura and microlabis subgroups form the basal clade in the obscura group. Partial species of the obscura subgroup (the D. ambigua/D. obscura/D. tristis triad plus the D. subsilvestris/D. dianensis pair) forms a monophyletic group which appears to be most closely related to the sinobscura subgroup. The remaining basal relationships in the obscura group are not resolved by the present study. Divergence times on a ML tree based on mtDNA data are estimated with a calibration of 30–35 Mya for the divergence between the obscura and melanogaster groups. The result suggests that at least half of the current major lineages of the obscura group originated by the mid-Miocene time (~15 Mya), a time of the last developing and fragmentation of the temperate forest in North Hemisphere. The obscura group began to diversify rapidly before invading into the New World. The subobscura and microlabis subgroups form the basal clade in this group. The obscura subgroup is paraphyletic. Partial members of this subgroup (D. ambigua, D. obscura, D. tristis, D. subsilvestris, and D. dianensis) form a monophyletic group which appears to be most closely related to the sinobscura subgroup.
