The dipteran family Coenomyiidae was firstly separated from the Xylophagidae by Akrira Nagatomi in 1975. We sequenced and annotated the mitochondrial genome of , the first representative of genera with complete mitochondrial data. This mitogenome is 17,283 bp totally, which consists of 22 transfer RNAs, 13 protein-coding genes, 2 ribosomal RNAs, and 1 non-coding control region. All genes have the conservational arrangement like other published species of brachyceran flies. The nucleotide composition biases toward A and T, the overall A + T% was up to 75.4% of the entire mitogenome. Both Bayesian inference and ML analysis strongly supported the sister relationship between Coenomyiidae and Xylophagidae. Our results also suggested that Xylophagomorpha is the sister group to Stratiomyomorpha.
1975年，长谷富秋首次将双翅目粪蝇科从蛀木蝇科中分离出来。我们对粪蝇属的首个具有完整线粒体数据的代表物种的线粒体基因组进行了测序和注释。这个线粒体基因组全长17283 bp，由22个转运RNA、13个蛋白质编码基因、2个核糖体RNA和1个非编码控制区组成。所有基因都具有与其他已发表的短角亚目蝇类物种相似的保守排列。核苷酸组成偏向于A和T，整个线粒体基因组的A+T%高达75.4%。贝叶斯推断和最大似然分析都强烈支持粪蝇科和蛀木蝇科之间的姐妹关系。我们的结果还表明，蛀木蝇亚目是水虻亚目的姐妹群。
