Complete mitochondrial genome of Scythris sinensis (Lepidoptera: Scythrididae).

The complete mitochondrial genome (mitogenome) of Scythris sinensis Felder & Rogenhofer, 1775 (Lepidoptera: Scythrididae) was 15,216 bp with a typical set of genes (13 protein-coding genes [PCGs], 2 rRNA genes, and 22 tRNA genes) and one non-coding region, with an arrangement identical to that observed in most lepidopteran genomes. Twelve PCGs had the typical ATN start codon, whereas COI had the atypical CGA codon that is frequently found in the start region of the lepidopteran COI. The 271-bp long A + T-rich region was the shortest among sequenced Gelechioidea, which ranged from 290 - 375 bp. Phylogenetic analyses with concatenated sequences of the 13 PCGs, two RNA genes, and 22 tRNA genes using the Bayesian inference (BI) method, placed S. sinensis in the Scythrididae, as a sister to the family Stathmopodidae. The nodal support for this sister relationship was the highest at Bayesian posterior probabilities = 1.
