The long-legged fly belongs to the subfamily Xanthochlorinae of Dolichopodidae. The mitogenome of was sequenced, it is the first representative complete mitogenome from this subfamily. This mitogenome is 15,580 bp in size, includes 13 protein-coding genes, 22 transfer RNAs, and two ribosomal RNAs. All genes have the same location and coding strand as in other published species of Dolichopodidae. Nucleotide composition is biased toward A and T, which together made up 77.6% of the entire genome. Bayesian inference strongly supported the monophyly of Empidoidea, Empididae and Dolichopodidae, with the phylogenetic relationships within Empidoidea: ((Dolichopodinae + Xanthochlorinae) + Neurigoninae) + ((Trichopezinae + (Empidinae + Oreogetoninae)) + Ocydromiinae).
长足虻属于长足虻科黄氯长足虻亚科。对其线粒体基因组进行了测序，这是该亚科的首个代表性完整线粒体基因组。该线粒体基因组大小为15580 bp，包括13个蛋白质编码基因、22个转运RNA和两个核糖体RNA。所有基因的位置和编码链与其他已发表的长足虻科物种相同。核苷酸组成偏向于A和T，它们共占整个基因组的77.6%。贝叶斯推断强烈支持舞虻总科、舞虻科和长足虻科的单系性，以及舞虻总科内的系统发育关系：((长足虻亚科 + 黄氯长足虻亚科) + 新长足虻亚科) + ((毛长足虻亚科 + (舞虻亚科 + 山舞虻亚科)) + 滨长足虻亚科)。
