(1) Background: is a major parasite of large porpoises and whales and has been classified in the Habronematoidea family. However, there has been a great controversy regarding its classification. Mitochondria have an important function in revealing taxonomic and evolutionary history. (2) Methods: In this study, we sequenced the mitochondrial genome of and conducted a phylogenetic analysis with the mitochondrial sequences of species belonging to the Habronematoidea family. (3) Results: The complete mitochondrial genome was 13,604 bp and it has an AT-rich sequence and one non-coding region (NCR). The reconstruction of the ancestral state showed that the gene orders of all species in Spirurina were conserved. The phylogenetic tree indicates that is closer to (Physalopteroidea) than (Habronematoidea). (4) Conclusions: This study provides new evidence that is phylogenetically closer to Physalopteroidea at the molecular taxonomic level.
(1) 背景：是大型鼠海豚和鲸鱼的主要寄生虫，已被归类于旋尾线虫超科。然而，关于其分类一直存在很大争议。线粒体在揭示分类学和进化历史方面具有重要作用。(2) 方法：在本研究中，我们对的线粒体基因组进行了测序，并与旋尾线虫超科物种的线粒体序列进行了系统发育分析。(3) 结果：完整的线粒体基因组为13,604 bp，具有富含AT的序列和一个非编码区（NCR）。祖先状态的重建表明，旋尾线虫属所有物种的基因顺序是保守的。系统发育树表明，与（泡翼线虫超科）相比，与（旋尾线虫超科）的亲缘关系更近。(4) 结论：本研究提供了新的证据，表明在分子分类水平上，与泡翼线虫超科在系统发育上更接近。
