We sequenced most of the mitochondrial (mt) genomes of 2 apocritan taxa: Vanhornia eucnemidarum and Primeuchroeus spp. These mt genomes have similar nucleotide composition and codon usage to those of mt genomes reported for other Hymenoptera, with a total A + T content of 80.1% and 78.2%, respectively. Gene content corresponds to that of other metazoan mt genomes, but gene organization is not conserved. There are a total of 6 tRNA genes rearranged in V. eucnemidarum and 9 in Primeuchroeus spp. Additionally, several noncoding regions were found in the mt genome of V. eucnemidarum, as well as evidence of a sustained gene duplication involving 3 tRNA genes. We also report an inversion of the large and small ribosomal RNA genes in Primeuchroeus spp. mt genome. However, none of the rearrangements reported are phylogenetically informative with respect to the current taxon sample.
我们对两个细腰亚目类群的大部分线粒体（mt）基因组进行了测序：范霍尼亚拟郭公虫（Vanhornia eucnemidarum）和普里默克罗伊属（Primeuchroeus spp.）。这些线粒体基因组的核苷酸组成和密码子使用情况与已报道的其他膜翅目线粒体基因组相似，A + T总含量分别为80.1%和78.2%。基因含量与其他后生动物线粒体基因组相对应，但基因组织并不保守。在范霍尼亚拟郭公虫中有总共6个tRNA基因发生了重排，在普里默克罗伊属中有9个。此外，在范霍尼亚拟郭公虫的线粒体基因组中发现了几个非编码区，以及涉及3个tRNA基因的持续基因重复的证据。我们还报道了普里默克罗伊属线粒体基因组中大小核糖体RNA基因的倒位。然而，就当前的分类群样本而言，所报道的重排均无系统发育信息。
