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.

2018년과 2019년 봄철에 전남 광양의 일부 자두(Prunus salicina Lindl.) 과수원에서 어린 과실을 낙과시켜 심각한 피해를 일으키는 새로운 해충을 채집하여 사육한 후 우화한 성충을 분류동정한 결과, 국내미기록종인 자두수염잎벌(신칭; Monocellicampa pruni Wei)로 확인되어 보고한다. 또한 이 해충의 피해 상황과 분류학적 특징을 기재함과 동시에 수컷생식기의 특징을 도해하여 제시하였다.

Harpiphorus, a monotypic genus of subfamily Allantinae (Symphyta: Tenthredinidae), was established based on Tenthredo (Emphytus) lepida Klug. The genus is close to Hemibeleses Takeuchi but can be easily distinguished by the following characteristics: the cell 1M in fore wing with a distinct petiole dorsally and cell M in hind wing closed. Harpiphorus is widely distributed in Europe, but has not yet been found in outside the continent. The larva of this genus is phytophagous attacking the oak species (Quercus trojana Webb and Q. robur L.). As a result of the present study, the genus Harpiphorus is reported based on H. lepidus for the first time from South Korea and the Eastern Palaearctic region. A diagnosis, figures of morphological features are provided.

Monsoma is a small and rarely collected genus within Allantinae, consisting of four species widely distributed in Palaearcticand Nearctic regions: M. faustum Zhelochovtsev, 1961; M. inferentium (Norton, 1868); M. pallipes (Matsumura, 1912);M. pulveratum (Retzius, 1783). This genus is morphologically similar to Empria Lepeletier & Serville, however, can bedistinguished by the abdominal terga without pale detached paired patches, cross-vein m-cu present and cell M closedon the hind wing.In the present study, the genus Monsoma is reported from South Korea for the first time based on M. pallipes. Adetailed redescription, photographs of the diagnostic characters are provided.

Filixungulia, a small genus within the subfamily Allantinae (Symphyta: Tenthredinidae), consists of three species distributed only in Northern China: F. alboclypea Wei, 1997; F. crassitarsata Wei, 1997; F. cylindrica Wei, 2003. It is close to Asiemphytus Malaise and Macremphytus MacGillivray but is separated by the following characteristics: claws simple and very slender; basal lobe and inner tooth absent. Up to date, Filixungulia has not yet been recorded out of China. As a result of the present study, the genus Filixungulia is newly recognized from South Korea with two species, F. alboclypea and F. cylindrica. This discovery extends the range of the genus Filixungulia, which was previously known as a Chinese endemic genus. Also, a key, diagnosis and photographs of each species are provided.

The subfamily Allantinae is one of the large subfamilies within the family Tenthredinidae with about 900 described species in the world. All of the species are worldwide distributed and 322 of them are from Eastern Palaearctic region. Also, in the neighboring countries, it has been recorded that 275 species in China, 90 species in Japan and 131 species in Russia. But only 15 species have been reported in South Korea. Generally subfamily Allantinae can be easily recognized from other subfamilies by the following characters in fore wing: Veins M and Rs+M meeting Sc+R at or very near the same point; vein 2A+3A complete, always separated from 1A by an anal crossvein; veins M and 1m-cu parallel; vein 2r present. Moreover, all larvae of Allantinae are phytophagous and external feeders on the foliage of the host. In this study, we report eight species belonging to the five genera (Allantus, Ametastegia, Apethymus, Asiemphytus and Taxonus) from South Korea for the first time. As a total of 11 genera and 24 species in Allantinae were identified to occur in South Korea. A key, diagnoses and photographs of the diagnostic characters are provided.
