| Popis: | The Symphyta has long been recognized as a paraphyletic grade forming the base of the remaining Hymenopteran, and the superfamily relationships within Symphyta remain controversial. Here, the first two representative mitochondrial genomes from the superfamily Siricoidea and Xiphydrioidea (Hymenoptera: Symphyta) are obtained using next-generation sequencing. The complete mitochondrial genome of Xiphydria sp. is 16,482 bp long with an A + T content of 84.18% while the incomplete one of Tremex columba is 16,847 bp long and A + T content is 81.69%. All 37 typical mitochondrial genes are possessed in both species. The secondary structure of tRNAs and rRNAs for both species are successfully predicted. Compared with the ancestral organization, seven and five tRNA genes are rearranged in mitochondrial genomes of Tremex and Xiphydria, respectively, which are the most rearrangement events within Symphyta. The rearrangement patterns in Tremex and Xiphydria present in this study are all novel to the Symphyta. Phylogenetic relationships among the major lineages of Symphyta are reconstructed using mitochondrial genomes. Both maximum likelihood and Bayesian inference analyses highly support Symphyta is a paraphyletic grade, Xyeloidea + (Tenthredinoidea + (Pamphilioidea + (Xiphydrioidea + (Cephoidea + (Orussoidea + Apocrita))))). |
