Cerace xanthocosma Diakonoff, 1950 belongs to the Tortricidae of Lepidoptera, distributed in China and Japan. Its mitochondrial genome is 15,344 bp in size, containing 37 genes (13 protein-coding genes, 2 ribosomal RNA genes, and 22 transfer RNA genes) and a non-coding A + T-rich region. In the 37 genes, 14 genes are located on the minority-strand (N-strand) with the remaining genes on the majority-strand (J-strand). The A + T-rich region has a poly-T stretch and a motif ATAGA. Phylogenetic analysis using Bayesian Inference method shows the sister relationship between Tortricinae and Olethreutinae with the placement of C. xanthocosma as the basal lineage of Tortricinae.
