Complete mitochondrial genome of Cerace xanthocosma and its phylogenetic position in the family Tortricidae.

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.
