Complete mitochondrial genome of the clearwing moth <i>Synanthedon namdoelegans</i> Kim, Kim and Choi, 2025 (Lepidoptera: Sesiidae)

The clearwing moth Synanthedon namdoelegans Kim, Kim and Choi, 2025 (Lepidoptera: Sesiidae) was newly discovered in South Korea in 2024. We sequenced 15,578 bp-long complete mitochondrial genome of the species. It contained the trnQ–trnS2–trnM–trnI arrangement at the A + T-rich region and ND2 junction (the underline indicates counterclockwise direction) unique to tribe Synanthedonini. Phylogenetic analyses of 18 Cossoidea species supported the monophyly of each Synanthedonini and Synanthedon, and revealed a sister relationship between S. namdoelegans and Synanthedon bicingulata (Staudinger 1887). These data will be useful in taxonomic, molecular ecological, and pest management research.
