The acalyptrate fly superfamily Opomyzoidea, as currently recognized, is a poorly-known group of 14 families. The composition of this group and relationships among included families have been controversial. Furthermore, the delimitation of two opomyzoid families, Aulacigastridae and Periscelididae, has been unstable with respect to placement of the genera Stenomicra, Cyamops, and Planinasus. To test the monophyly of Opomyzoidea, previously proposed relationships between families, and the position of the three problematic genera, we sequenced over 3300bp of nucleotide sequence data from the 28S ribosomal DNA and CAD (rudimentary) genes from 29 taxa representing all opomyzoid families, as well as 13 outgroup taxa. Relationships recovered differed between analyses, and only branches supporting well-established monophyletic families were recovered with high support, with a few exceptions. Opomyzoidea and its included subgroup, Asteioinea, were found to be non-monophyletic. Stenomicra, Cyamops, and Planinasus group consistently with Aulacigastridae, contrary to recent classifications. Xenasteiidae and Australimyzidae, two small, monogeneric families placed in separate superfamilies, were strongly supported as sister groups.
目前已知的无翅蝇超科（Opomyzoidea）是一个鲜为人知的 14 科群组。该群组的组成和包含的科之间的关系一直存在争议。此外，两个 Opomyzoidea 科（Aulacigastridae 和 Periscelididae）的界限一直不稳定，涉及到 Stenomicra、Cyamops 和 Planinasus 属的归属问题。为了测试 Opomyzoidea 的单系性、先前提出的科之间的关系以及这三个有问题的属的位置，我们从代表所有 Opomyzoidea 科的 29 个分类单元以及 13 个外群分类单元的 28S 核糖体 DNA 和 CAD（原始）基因中测序了超过 3300bp 的核苷酸序列数据。恢复的关系在分析之间存在差异，只有支持明确的单系科的分支才得到高度支持，只有少数例外。Opomyzoidea 及其包含的亚组 Asteioinea 被发现是非单系的。与最近的分类相反，stenomicra、Cyamops 和 Planinasus 属与 Aulacigastridae 一致。两个小型的单属科 Xenasteiidae 和 Australimyzidae 被强烈支持为姐妹群，它们被分别置于不同的超科中。
