摘要：

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.
