섬중베짱이(Tettigonia jungi Storozhenko, Kim & Jeon, 2015)는 제주도와 여서도 등의 남부 섬 지역에만 서식하는 종으로 알려져 있다. 본 연구는 야외조사와 형태 동정, 미토콘드리아 COI을 이용한 분자동정을 통해 서울특별시 마포구 상암동 하늘공원에서 섬중베짱이의 서식을 확인하였다. 유입된 섬중베짱이 개체군들은 주변 환경으로 분산되지 못하고 하늘공원에 고립되어 있다. 이 소규모 개체군들은 최소 하늘공원이 조성된 직후인 2003년부터 고립되어 서식해왔으며, 공원을 조성하는 과정에서 제주도산 억새와 함께 유입되어 정착한 것으로 추측된다.

Athalia japonica (Klug, 1815) is a significant insect pest of turnips in Korea. The complete mitochondrial genome of this species isolated in Korea is reported in this study, which is the first attempt to study Korean Athalia species. The circular genome is 15,662 bp in length and consists of 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and an A+T-rich region. Consistent with most members of the genus Athalia, five of the tRNA genes are rearranged from the typical ground pattern of ancestral insect gene order. Phylogenetic analyses inferred from the nucleotide sequences of 25 mitochondrial genomes indicate that the Korean A. japonica is a distinct member of the genus Athalia. This study accumulates mitochondrial genome data of A. japonica from various countries, providing useful information on mitochondrial genetic differences across geographical distances in the East Asian region.

The North Korean sawflies housed in the Hymenoptera Collection of the Hungarian Natural History Museum are studied, with a focus on the subfamilies Athaliinae and Allantinae. Five genera and ten species of the two subfamilies are identified. Athalia indiana Benson is reported for the first time from East Asia (North Korea), and further eight species and one subspecies are discovered in the new country of North Korea: Allantus helanshanicus Wei, Li and Xiao, Apethymus kolthoffi (Forsius), A. sidorenkoi Sundukov, Athalia japonica (Klug), A. proxima (Klug), A. rosae ruficornis Jakowlew, Beleses satonis (Takeuchi), Taxonus carbonarius Takeuchi, and T. montanus Togashi. Additionally, Athalia infumata (Marlatt) syn. nov. is considered a junior subjective synonym of A. proxima (Klug). Diagnoses and photographs of the newly recorded species are provided, as well as new distributional records and brief notes on the new synonymy.

Nialoe Tanaka, 1958 is a subgenus of the ground beetle genus Pterostichus (Coleoptera: Carabidae), endemic to East Asia. In a wide sense of Nialoe, it consists of more than 200 species, which has reduced hindwing and possibly diversified by geographical isolation due to poor dispersal ability. To understand this vast group, phylogenetic studies have been conducted, showing that Nialoe s. lat. comprises of five subgenera: Nialoe s. str., Sphodroferonia, Koreonialoe, and two unnamed subgenera. However, there is little knowledge regarding their origin and dispersal. In this study, we examine phylogenetic relationships among the five subgenera of Nialoe s. lat. based on 28S rRNA, wingless, COI, and 16S rRNA. The molecular clock and S-DIVA analyses are devised to investigate the biogeographical history of the group in East Asia. This study may give insight into the biogeographical dispersal and diversification of East Asian carabids.
