“…COI, 16S rRNA, and ITS region sequences for S. depressiusculum and S. frequens from previous studies were downloaded from GenBank [31][32][33][34][35] (Futahashi et al, unpublished data). The compiled sequences consisted of 6 sequences each from COI, 16S rRNA, and ITS sourced from Japan; 23 sequences from both COI and 16S rRNA, as well as 19 ITS sequences from Russia; and 10 sequences both from COI and 16S rRNA, in addition to 6 ITS sequences from The Netherlands (Table S3).…”

“…These calculations were conducted using PAUP version 4.0b [36]. The alignment of each gene (or region for ITS) included Sympetrum infuscatum as an outgroup for subsequent phylogenetic analyses (Gen-Bank accession numbers LC366870 for COI, LC366573 for 16S rRNA, and LC366276 for ITS region) [33]. This alignment was conducted using MAFFT version 7 [30] and was further adjusted to align with GenBank data lengths using Gblock 0.91b [37], which resulted in a reduction of the ITS region alignment from 805 to 746 bp.…”

In South Korea, both Sympetrum depressiusculum Sélys, 1841 (Odonata: Libellulidae), which is distributed throughout Europe and from Russia to the Korean Peninsula, and Sympetrum frequens Sélys, 1883, which is endemic to Japan, are recorded. However, the identity of South Korean populations and the validity of listing the two species have not yet been settled. In this study, we collected seventy-four individuals of Sympetrum species from South Korea (five localities), Russia, The Netherlands, and Japan. These samples were examined for morphology and sequenced for partial COI, 16S rRNA, and a nuclear internal spacer (ITS) region, after which these molecular data were combined with available public data from Russia, Japan, and The Netherlands. Major morphological characters that have been used to distinguish the two species and phylogenetic, network, and structure analyses all consistently suggest that South Korean populations form a single species. Consequently, it could be valid to treat South Korean populations as one species, S. depressiusculum, by applying the senior name. Nevertheless, the validity of maintaining each as an independent species in other countries may need additional study considering that our samples were focused more on South Korea and limited for Europe, Russia, and Japan.
