Rotylenchus pini Mamiya, 1968 was reported from rhizospheric soils of Zoysia japonica in Korea. Females and males of the characterized population conform to the original species description from Japan and also to other subsequent species descriptions with variations in a few details in morphometrics including the existence of pharyngeal gland overlap in some specimen. Bayesian analysis of all the three DNA markers consistently grouped R. pini together with Rotylenchus species including R. zhongshanensis, a morphologically close species. Additionally, the newly obtained sequences of R. pini were found to be almost identical to the sequences assigned to Rotylenchus aff. devonensis in GenBank. These Rotylenchus aff. devonensis isolates might be representatives of R. pini populations. The current and previous phylogenetic studies supported by the recorded morphological plasticity within populations of the genus validate the proposed synonymy of Pararotylenchus with Rotylenchus.

Until now, in case of Palaearctic region, only one species, Nesendaeus monochrous in this genus was recorded from China. but the biology and life cycle are not clearly known, yet. This species collected from the bud of Glochidion chodoense in Korea for the first time and closely related to Heterochyromera imerodeus Kojima & Morimoto which was recorded only in Japan,. But Nesendaeus monochrous is easily distinguishable from H. imerodeus by the relatively longer elytra with bisinuately round apices. Heterochyromera imerodeus Kojima & Morimoto can be found from Eurya emarginata and Glochidion obovatum in Japan. So, this two species are closely related each other and need more taxonomic study about the generic synonymy or changing the generic position.

The onion thrips, Thrips tabaci, is a serious global pest attacking many agricultural crops such as onion and Welsh onion. The thrips, assumed to originate in the Mediterranean region, has been reported for a long time in South Korea. According to worldwide molecular works, the species composes of three genetic lineages (LI, L2 and T) which related to reproductive mode (arrhenotoky vs. thelotoky). To understand the genetic diversity of T. tabaci in South Korea, we investigated genetic lineage and haplotype composition, using about 80 mitochondrial COI gene sequences (369bp) along with foreign sequences from GenBank and BOLD. The COI gene analysis shows that both of thelotokous L1 and arrhenotokous L2 population distribute in South Korea. Among 97 COI-haplotypes worldwide, only six haplotypes are found and thelotokous H1 dominantly distributes.

The family Periscelididae Oldenberg is reported for the first time from Korean fauna along with three nominate species, Cyamops hotei Sueyoshi, 2004, Stenomicra angustiforceps Sabrosky, 1965 and S. fascipennis Malloch, 1927. Stenomicra have been collected at grassy areas, whereas Cyamops have been founded near wet habitats. The descriptions and illustrations of external features of these species are provided here.

Curtonotidae, known as the quasimodo flies, in Diptera currently includes about 100 described species in five genera (Axinota Wulp, 1886; Curtonotum Macquart, 1844; Cyrtona Séguy, 1938; Depressonotum Grimaldi & Kirk-Spriggs, 2012; Tigrisomyia Kirk-Spriggs, 2010) worldwide. Curtonotid species have great potential as case studies for biological diversity, evolution, and zoogeography based on wide distribution and sufficient diversity. In the present study, Curtonotum maritimum Ozerov, 2007 is newly added to Korean insect fauna. This is also the first record of Curtonotidae from the country. We here provide morphological diagnosis and images including genitalic structures for accurate identification.

Milichiidae Schiner, 1862 is a small family of Diptera, with 19 genera and 360 described species worldwide. In Korea, only two species in a single genus, Aldrichiomyza Hendel, 1914, have been recorded. Milichiid species, small-sized acalyptrate flies, are generally associated with decaying plants and animals. In particular, Desmometopa Loew, 1866 in the family has a commensalistic habit, more precisely the phoretic relationship, that has been observed with predacious insects and spiders, in which adults feed on the juices of the prey. In this study, we recognized Desmometopa microps Lamb, 1914 for the first time in the Korean Peninsula. This is also the first record of the genus from the country. Herein, we provide diagnosis of D. microps based on the Korean specimens with images.

Fall armyworm Spodoptera frugiperda (Lepidoptera: Noctuidae) is a polyphagous agricultural pest that damages about 80 species of plants. It mainly damages Poaceae and plants used as food resources for humans. Its original habitat is the American continent, but it unintentionally settled in tropical and subtropical Asia, including Africa, India, and Sri Lanka. It occurs every year even in southern China, which is geographically adjacent to the Korean Peninsula, causing damage to crops. In Korea, it was first discovered on Jeju Island in June 2019 and is being discovered every year in Jeju and some inland areas. In 2023, there were a total of 13 discoveries, including those in the Jeju and Jeonbuk regions. Quarantine agency identified the maternal genotypes of all currently discovered individuals using COI and identified differences in genetic traits between individuals using the sex-related Z-chromosome. For comparison with the information on the individuals that invaded the country, 15 individuals from Guangxi and Guangdong provinces in China were collected and secured. Through the analysis of overseas samples, a database has been added to compare genetic information with domestic invasive species, and the reliability of the analysis is expected to increase.

The tribe Tropidocephalini Muir, 1915 (Delphacidae: Delphacinae) comprised 37 genera 204 species worldwide. In Korea, only three species, Epeurysa nawaii Matsumura, 1900, Tropidocephala brunnipennis (Distant, 1906), T. nigra (Matsumura, 1900), have been reported. In this study, one species, Epeurysa distincta Huang & Ding, 1979, is reported for the first time from Korea. We provide the morphological characteristics, photographs and taxonomic keys of the four species belonging to the tribe Tropidocephalini.

Solenopsis invicta, known as the red imported fire ant, is an insect native to South America. This species was unintentionally introduced into Australia, New Zealand, several Asian countries, Caribbean countries, and the United States. It shows a high survival rate and settlement potential in human-habitable and non-living areas such as tropical rainforests, disturbed areas, deserts, grasslands, and roads. In Korea, invasions of red fire ants have been reported every year since 2017, and two invasions were discovered in 2023. Quarantine agency analyzing the haplotype and colony social type of S. invicta for surveillance and control. Population genetic analysis using Microsatellite Alleleic data of 66 loci to trace the origin of the invasion. Through research cooperation with the United States Department of Agriculture (USDA), we have received samples and expanded our genetic information database. This study analyzed genetic differences between 15 invasive populations and 44 reference groups. As a result of microsatellite analysis, the domestic invasive population showed a genetic structure similar to those in Guangzhou, China, and Florida, USA.
