Mitochondrial genomes (mitogenomes) have been used widely in comparative and evolutionary genomics, molecular evolution, phylogenetics, and population genetics, but very limited information is available for the family Cynipidae. In this report, we described the mitogenome of Andricus mairei. The mitogenome of A. mairei was 16,514 bp in length and contained a typical set of 37 genes. Two control regions (CRs) were detected, one being a partial reverse repeat of the other. In a comparison with the putative ancestral mitogenome, gene rearrangements were found in transfer RNA (tRNA) genes, protein...
