Hypsopygia is characterized by the elongated uncus and valva, and pointed saccus in the male genitalia. It consists of 105 described species (Nuss et al., 2003–2024) in the world, and 11 species have been recorded in Korea (Kim & Paek, 2020; Shin et al., 2023). In this study, we reported one newly recorded species in Korea. Illustrations of adults provided, with information of host plants of all examined species.

The Miltogramminae (Diptera: Sarcophagidae) includes 600 species divided into more than 40 genera. The biological feature of the miltogrammine species is being kleptoparasites in the nests of solitary wasps and bees, but insect parasitoids and termite inquilines have been also recorded. In Korea, only three species in two genera have been recorded. In this study, five unrecorded species (Amobia oculata, Metopia inermis, Metopia nudibasis, Miltogramma angustifrons and Phylloteles formosana) are reported for the first time in Korea. The diagnosis, photographs and checklists are provided herein.

The genus Olethreutes, established by Hübner in 1822, is based on the type species Phalaena arcuella Clerk, 1759. Olethreutes is one of the largest group within the family Tortricidae, with more than 130 species worldwide. As of now, about 31 species of the genus Olethreutes have been reported in the Korean peninsula. The proposes of this study is to describe one new species, with three similar species form Korea.

Native to southern Europe, Lepisiota frauenfeldi (Mayr, 1855) is an invasive species that has been introduced worldwide through cross-border trade. It has been documented to be distributed in the Mediterranean, Middle East, Africa, and Indo-Malaya. This species, also known as Browsing ant, was first found around a warehouse in Gwangyang, Jeollanam-do, South Korea, and was probably introduced into the country via cargo. The external morphology and gene sequences were checked for taxonomic identification, and it was identified as Lepisiota frauenfeldi based on comparative analysis of the morphological classification key and NCBI data. This study is the first report of a newly invasive alien ant and provides basic data on the species, including external morphological and ecological features and sequencing results.

The genus Trichophysetis is one of the taxa that has recently undergone frequent changes in its taxonomic position. Only four species have been recorded in Korea, including synonymized Hendecasis species. Recent studies on the taxonomic classification of Trichophysetis have not addressed any species inhabiting Korea. Therefore, it is necessary to conduct a renewed morphological analysis of Korean species. In this study, we compare and analyze four Korean Trichophysetis species with one newly recorded species.

The Genus Psectra is a small group of Hemerobiidae, and Psectra diptera is one of the rare and attractive species in this group because of hindwing variation. They are well known to have their hindwing reduced, similar to flies, depending on their habitat environment. We report Genus Psectra and Psectra diptera, new records from Korea. We provide brief descriptions and photos of adults and genitalia.

Mantidflies or Mantid lacewing (Mantispidae) is a morphologically interesting group of Neuroptera. This group is a general predator of arthropods and is equipped with raptorial forelegs similar to praying mantis. In Korea, only three species, Climaciella quadrituberculata, Mantispa harmandi, and Mantispilla japonica, are recorded until now. Here we report Genus Necyla and Necyla formosana, new records in Korea. We provide diagnostic character and photos of adult and genitalia.

We analyzed trends of ants intercepted on imported plants and lumber over the past 30 years, using data extracted from the Pest Information System (PIS). There were 1,629 cases of about 112 species (5 subfamilies, 45 genera) from planting plants such as Asparagales, Alismatales, and Saxifragales, and 2,217 cases of about 86 species (7 subfamilies, 42 genera) from lumbers such as square lumber, pellets, and solid wood. For intercepted trends by continent, Asia was the most frequently detected at 91%, followed by Europe at 1% and North America at nearly 1%. Among Asian countries, Malaysia (27%) represented the highest number of interceptions, followed closely by Indonesia at 26%.

Melanoplus differentialis (Thomas, 1865) is a widely distributed Orthopteran species in North America, including the United States and Mexico. Known for causing damage to various crops such as vegetables and grains throughout its lifecycle. In South Korea, it has been observed concentratedly in the vicinity of the Onsan National Industrial Park in Ulsan and was designated as “Ecosystem Disturbing Species” by Ministy of Environment in 2020. This study aims to present foundational data on pest management strategies for Melanoplus differentialis identified within the Onsan National Industrial Park. Through collaborative efforts between the National Institute of Ecology, related agencies, and tenant private companies from 2020 to 2023, we will demonstrate the reduction in habitat area as a result of proactive pest control measures.

A surveillance of chigger mites was performed to monitor the incidence of scrub typhus vectors at four environmental collection points in two locations (Sunchang and Haenam) in the Honam region of Korea from August to December 2023. During the surveillance period, 4,174 chigger mites were collected and the predominant species were Leptotrombidium scutellare (94.3%). The density of chigger mites had the peaked at 44 week (10.26~11.1), while the density of patients peaked at 45 week (11.2~11.8) respectively. A positive correlation (r=0.69) observed between scrub typhus patients and vectors. This result suggests that this vector surveillance method will be useful for alarm system of tsutsugamushi disease. However, the relationship between scrub typhus cases and chigger mite density will be studied through long-term periodic surveillance.

2023년에 국내에서 보고된 적이 없던 외래흰개미 3종이 각각 인천, 서울, 창원에서 발견되었다. 종 동정 결과, 인천에서 출현한 종(Coptotermes gestroi)은 Subterranean termite로 밝혀졌으며, 서울과 창원에서 출현한 종 (Cryptotermes domesticus, Incisitermes minor)은 Drywood termite로 밝혀졌다. 본래 우리나라에는 Subterranean termite 흰개미가 2종이 분포하고 있다고 보고되어 있었으나, 새로운 과 또는 속의 외래흰개미가 발견되면서 국민 들의 우려가 커지고 있다. 국내에서는 일부 외래흰개미를 법적으로 지정(유입주의 생물 2종, 관리병해충 15종)하 여 관리하고 있는데, 해당 흰개미와 그 외의 신규 흰개미의 출현으로 인한 피해가 우려되는 상황이다. 본 연구에서 는 ‘23년 유입된 3종 및 기존 법정관리 외래흰개미, 그리고 국내 유입과 위해가 우려되는 외래흰개미 5과 (Archotermopsidae, Kalotermitidae, Rhinotermitidae, Termitidae, Termopsidae)를 조사하였으며, 이들의 생태적 특 징과 외국의 사례를 통해 외래흰개미 대비 방법에 대하여 고찰하였다.

The large copper butterfly Lycaena dispar (Haworth, 1803; Lepidoptera: Lycaenidae) has been categorized as a near-threatened species (NT) in South Korea from 2012 mainly due to limited distribution. In this study, we visited 36 sites spread across all South Korean provinces to verify the distributional range of the species and sequenced mitochondrial COI for 53 individuals from nine sites. We observed L. dispar at 15 sites in six provinces, including the two previously known provinces, indicating a southward range expansion. The in-field monitoring and genetic data collectively suggested that L. dispar does not have a limited distribution nor is it isolated, indicating that it should be reclassified as less vulnerable. Our study demonstrates that the combination of field and genetic data can provide a more reliable assessment of the stability of a species.
