硫磺蝴蝶，Colias spp.，粉蝶科及其近缘种一直是行为学、生态学和进化学研究的对象。然而，它们的起源在许多方面是不确定的。我们使用来自2个线粒体基因块的DNA序列，333 bp的细胞色素氧化酶I亚基（CO I）和1,261 bp的2个核糖体基因及其之间的tRNA（rDNA）作为特征来源，以测试现有的系统发育假设，并开始推断其他。rDNA块在染色体发生的较深节点处解析得更好，而CO I块在较浅节点处解析得更好。我们的研究结果支持的姐妹地位的亚科Coliadinae和粉蝶亚科的粉蝶科;独立的部落地位的Eurobulini和粉蝶族的粉蝶亚科;地位的姐妹属Coliadinae和Zerene的Coliadinae;和单系内的亚属C。（Eucolias）所有北美Colias研究。我们的研究结果表明，新热带大肠杆菌属Eurema可能值得分裂，因为一些早期的工作者提出，但不支持最近提出的分裂欧亚C。erate亚属C.（Eriocolias）分为C.（Neocolias）。（鳞翅目：粉蝶科）
The sulfur butterflies, Colias spp., and their relatives in the family Pieridae have been the subjects of diverse behavioral, ecological, and evolutionary studies. However, their phylogeny is uncertain in many respects. We used DNA sequences from 2 mitochondrial gene blocks, 333 bp of the cytochrome oxidase I subunit (CO I) and 1,261 bp from the 2 ribosomal genes and the tRNA between them (rDNA), as character sources to test existing phylogenetic hypotheses and begin to infer others. The rDNA block resolves better at deeper nodes of the phylogeny, and the CO I block at shallower nodes. Our results support sister status for subfamilies Coliadinae and Pierinae within Pieridae; independent tribal status for Euchloini and Pierini within Pierinae; status as sister genera for Colias and Zerene within Coliadinae; and monophyly within subgenus C. (Eucolias) of all North American Colias studied. Our results suggest that the Neotropical coliad genus Eurema may warrant splitting, as some early workers proposed, but do not support the recently proposed splitting of Eurasian C. erate from subgenus C. (Eriocolias) into the separate subgenus C. (Neocolias) . (Lepidoptera: Pieridae)
