斑潜蝇总科是一个重要的双翅目昆虫分支，包括斑潜蝇总科、斑潜蝇总科和斑潜蝇总科3科2500多种。我们测序了前5个(3个完整和2个部分)月桂花序线粒体(Mt)基因组，并用它们重建了这个群体的系统发育。月桂类线粒体基因组是典型的双翅目昆虫，包含通常存在于双边动物中的所有37个基因。环状芽胞杆菌共有三个保守的基因间序列被报道。推测的22个tRNAs的二级结构表明，在环状结构中有5种替换模式。Laxanioidae中的控制区显然进化得非常快，但在所有三个完整的mt基因组序列中都检测到了四个保守的结构元件。基于mt基因组数据，用最大似然法和贝叶斯方法推断系统发育关系。环斑夜蛾总科(Chamaemyi idae+(Laxaniidae+Celyphidae))中科与科之间的传统关系得到了证实；然而，环斑夜蛾超科之间较高层次的关系大多缺乏支持。
The superfamily Lauxanioidea is a significant dipteran clade including over 2500 known species in three families: Lauxaniidae, Celyphidae and Chamaemyiidae. We sequenced the first five (three complete and two partial) lauxanioid mitochondrial (mt) genomes, and used them to reconstruct the phylogeny of this group. The lauxanioid mt genomes are typical of the Diptera, containing all 37 genes usually present in bilaterian animals. A total of three conserved intergenic sequences have been reported across the Cyclorrhapha. The inferred secondary structure of 22 tRNAs suggested five substitution patterns among the Cyclorrhapha. The control region in the Lauxanioidea has apparently evolved very fast, but four conserved structural elements were detected in all three complete mt genome sequences. Phylogenetic relationships based on the mt genome data were inferred by Maximum Likelihood and Bayesian methods. The traditional relationships between families within the Lauxanioidea, (Chamaemyiidae + (Lauxaniidae + Celyphidae)), were corroborated; however, the higher-level relationships between cyclorrhaphan superfamilies are mostly poorly supported.
