Empidoidea 代表了一个庞大且多样化的真蝇超家族，迄今为止，尚无关于系统发育的稳定假说。以前的分类是基于形态学数据，并且几个群体之间的关系仍然未知。在贝叶斯分析中，我们使用线粒体基因细胞色素氧化酶 c 亚基 I (COI) 和细胞色素 β (Cyt beta) 以及核基因初级羧酰磷酸合成酶结构域 (CAD)、延伸因子 1 α (EF-1 α) 和异柠檬酸脱氢酶 (IDH)，测试了这个果蝇大超家族中更高分类群的支持。我们重新评估了该群体内先前的进化假说，并提出了一个得到高度支持的系统发育假说。 Atelestidae、Dolichopodidae、Empididae 和 Hybotidae 被支持为单系科，Atelestidae 是其余 Empidoidea 的姐妹群。在 Hybotidae 家族中，Bicellariinae stat.n。与其他亚科形成姐妹群。 Ragadidae 家族 stat.n。建立包括 Ragadinae 亚科和新亚科 Iteaphilinae subfam.n.； Ragadidae 是 Empididae 的姐妹群。长足蝽科 (Dolichopodidae) 与蝽科 (Ragadidae) 和蝽科 (Empididae) 形成姐妹群。在 Empididae 中，Hemerodromiinae 被发现是一个非单系类群。 Hilarini 和 Hemerodromiini 部落。修订版被恢复为姐妹组，Empidini 和 Chelipodini stat 也是如此。修订版前科 Brachystomatidae 被发现嵌套在 Empididae 中。提供了非长足科、亚科和部落的修订分类和诊断。
Empidoidea represent a large and diverse superfamily of true flies, and to date no stable hypothesis on the phylogeny exists. Previous classifications have been based on morphological data and the relationships among several groups are still unknown. Using the mitochondrial genes cytochrome oxidase c subunit I (COI) and cytochrome beta (Cyt beta) and the nuclear genes carbomoylphosphate synthase domain of rudimentary (CAD), elongation factor-1 alpha (EF-1 alpha) and isocitrate dehydrogenase (IDH) in a Bayesian analysis, we tested the support of higher taxonomic groups within this large superfamily of flies. We re-evaluated previous hypotheses of evolution within the group and present a highly supported phylogenetic hypothesis. Atelestidae, Dolichopodidae, Empididae and Hybotidae were supported as monophyletic families, with Atelestidae as sister group to the remaining Empidoidea. Within the family Hybotidae, Bicellariinae stat.n. formed the sister group to the other subfamilies. The family Ragadidae stat.n. is established to include the subfamily Ragadinae and the new subfamily Iteaphilinae subfam.n.; Ragadidae was sister group to the Empididae. Dolichopodidae was found to form a sister group to Ragadidae plus Empididae. Within Empididae, Hemerodromiinae was found to be a nonmonophyletic group. The tribes Hilarini and Hemerodromiini stat. rev. were recovered as sister groups, as were Empidini and Chelipodini stat. rev. The former family Brachystomatidae was found to be nested within Empididae. A revised classification and diagnoses of nondolichopodid families, subfamilies and tribes are provided.
