Complete mitochondrial genomes of Ceratobaeus sp. and Idris sp. (Hymenoptera: Scelionidae): shared gene rearrangements as potential phylogenetic markers at the tribal level

Journal Article


Abstract


  • We sequenced the complete mitochondrial genomes of two sceliond taxa (Ceratobaeus sp. and Idris sp.). An atypical tRNA-Arg which lacks a D-stem was identified in both taxa, and represents a potentially derived character of sceliond wasps. A number of tRNA genes have rearranged in the two mitochondrial genomes compared with the ancestral organization. Some of these derived genome organizations are shared, and thus have much potential as phylogenetic markers at the tribal level in the subfamily Scelioninae. We test the influence of third codon inclusion/exclusion, alignment methods and partition schemes on the reconstruction of phylogenetic relationships. The results show that inclusion of third codon positions does not appear to be problematic when investigating the phylogeny of closely related taxa. Muscle and PartitionFinder schemes significantly improve the likelihood scores.
