The genus Muscidideicus Becker, 1917 is comprised of only one species, M. praetextatus (Haliday, 1855) reported in west Palearctic region. The adults were typically found on sandy beach within the intertidal zone. In the survey of Korean fauna, authors found three new to science species of this genus on the west sea side of Korean Peninsula and Jeju Island. Descriptions and figures of external features of new to science species and key to species of the world are provided here.

The genus Campylomyza Meigen, 1818, from the Micromyinae subfamily of the Cecidomyiidae, includes 40 known species globally. The genus Campylomyza has been primarily studied within the Palearctic region, with 39 species, 2 from the Nearctic region, and 1 from the Oriental region. As of now, four species have been documented in Korea: Campylomyza appendiculata, C. flavipes, C. furva, and C. spinata. Our research from 2017 to 2020 uncovered five previously unreported species in Korea (C. abjecta, C. aborigena, C. cornuta, C. cavitata, and C. cingulata) and introduces seven new species (C. angusta sp. nov., C. ambulata sp. nov., C. convexa sp. nov., C. cornigera sp. nov., C. hori sp. nov., C. odae sp. nov., and C. yeongyangensis sp. nov.). These findings are based on morphological evidence and DNA analysis. We present comprehensive data, including the mitochondrial COI sequences, diagnoses, detailed descriptions, and identification keys for these species. This work was supported by a grant from the National Institute of Biological Resources (NIBR), funded by the Ministry of Environment (MOE) of the Republic of Korea.

Neomyrhessus Minkina, 2024, is a rare genus comprising six species, recently erected from Myrhessus Balthasar, 1955 for N. nanjingensis. To date, all six species have been reported in East Asia, with five from Japan and one from China. In this study, the genus Neomyrhessus is recorded for the first time in South Korea, with the discovery of a new species Neomyrhessus coreanus sp. nov. Description, illustrations of morphological characters, and habitat information for a new species are provided.

The genus Trixagus Kugelann is one of the most diverse genera in the family Throscidae Laporte, which comprises about 80 species. Only a single species of this genus has been reported in Korea throughout the entire family. In this study, three additional species, Trixagus sp., Trixagus leseigneuri Muona, and Trixagus turgidus Hisamatsu are reported for the first time in Korea. Similar to that of the species illustrated in Kovalev, males of Trixagus leseigneuri Muona and Trixagus turgidus Hisamatsu possess sexual modification on mesotarsus. Trixagus sp. and Trixagus turgidus Hisamatsu exhibit characters that are unusual for this genus, including the unincised eye, a blade-like structure on the protibia, and others. Illustrations of habitus and diagnostic characters of each species are provided.

The genus Caenoscelis C. G. Thomson (Coleoptera: Cryptophagidae: Cryptophaginae) comprises approximately 30 species in the world, primarily distributed in the Holarctic region. Although 15 Caenoscelis species occur in the Palearctic region, only a single species, Caenoscelis sibirica Reitter, has been documented in Korea. In this study, Caenoscelis koreanus sp. nov. is described, and Caenoscelis ferruginea (C. R. Sahlberg) is reported for the first time in Korea. The new species can be distinguished from other Caenoscelis species by their subquadrate antennomere 10, fully developed hind wings, and male genitalia with subacute parameres and indistinctly separated lateral lobes. Illustrations of habitus, diagnostic characters, and a distribution map of Korean Caenoscelis species are provided.

The genus Megastylus is a moderate group of the subfamily Orthocentrinae, comprising 38 species in two subgenera from worldwide. The subfamily Orthocentrinae is a high proportion of the genera are cosmopolitan in distribution. Orthocentrines are known as almost solitary koinobiont endoparasitoids. We report this genus for the first time from South Korea. In this study, descriptions of some new species, photographs of diagnostic characterists are provided.

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.

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.

The genus Grapholita, belonging to the tribe Grapholitini under the family Tortricidae, which is small to medium-sized moths ranging from 7mm to 16mm. It is a relatively diverse group in Grapholitini, comprising more than 150 species worldwide. This group is generally distributed throughout the world, with the majority of its species occurring in the Holarctic region. Some species in the genus Grapholita are known worldwide as serious pests that feed on leaves, roots, fruits and other plant parts. In Korea, the genus is known to have 8 described species up to date. In this study, we report two newly recorded species of the genus Grapholita from Korea, including a brief description and illustrations of adult and genitalia. Additionally, all available information including distribution, host plants and a taxonomic key to Korean Grapholita species is provided.

The family Gelechiidae (Lepidoptera: Gelechioidea) is known as one of the largest families in Microlepidoptera, encompassing about 600 genera and more than 5,000 described species worldwide. However, the genus Altenia Sattler, 1960 has been poorly studied in Korea, with only one known species. Here we introduce a new species, Altenia parascriptella sp. nov., from Korea, providing photos of adults and genitalia for both sexes, along with diagnostic characteristics.

The genus Acronicta Ochsenheimer, 1816 is known as a forest pest. The acronictine species is widely distributed across the Afrotropical, Oriental, Australian, and Neartic regions. This study presents a new record of an acronictine species from Korea, including descriptions, illustrations, and diagnostic characteristics. Additionally, the CO1 barcode data of the newly recorded species is compared with the global barcode reference at the species level. New data on the recently recorded species has been obtained from this study. This information will aid in the prompt identification and preparation for potential pest outbreaks.

A taxonomic study was conducted on Spilonota Stephens, 1834 in Korea. As a result of the research based on materials from Incheon National University two new species; S. samseong Choi, Bae & Nasu, and S. laticucullusa Choi, Bae & Nasu from Korea. This study provides a brief description of the new Spilonota species in Korea, as well as comparisons with similar species and illustrations of adult and genital morphology.

The genus Cephennodes Reitter (Coleoptera: Staphylinidae: Scydmaeninae) comprises approximately 220 species worldwide within three subgenera (Cephennodes, Aculeodes, Fusionodes). In Korea, two species are recorded: C. (s. str) japonicus (Sharp) and C. (Fusionodes) graeseriReitter. The two subgenera, Cephennodes and Fusionodes, can be distinguished by the form of the parameres in relation to the median lobe, whether fused or divided. In this study, we redescribed two species: C. (s. str) japonicus and C. (Fusionodes) graeseri. Additionally, Cephennodes (Fusionodes) ussuricus (Kurbatov) is recorded first time in Korea. Images of habitus, aedeagus, and a distribution map are provided.

In addition, Dalmisus Sharp is placed as a junior synonym of Adalmus (gen. syn.) and the species Dalmisus batrisodes Sharp, 1886, Plectomorphus longiceps Broun, 1913 and P. longipes Broun, 1912 are placed as junior synonyms of A. velutinus Reitter, 1885 spp. syn. Also, P. rugiceps Broun, 1921 is transferred to the genus Adalmus, comb. nov. Adalmus now holds eight species.

A total of 187 species are involved in the genus Pidonia Mulsant (Coleoptera: Cerambycidae: Lepturinae) worldwide, of which 174 species are distributed in Eurasia. Since Bates recorded P. (P.) gibbicollis in 1888, a total of 17 species have been recorded in Korea. After An & Kwon’s study on Korean Pidonia in 1991, no taxonomic study has been carried out for almost 30 years, making it difficult to identify the species due to their mutations. In this presentation, we provide an update on the taxonomic study of Korean Pidonia and report a newly recorded species, P. (P.) obscurior hakusana, in Korea.

The genus Eudarcia belong to the subfamily Meessiinae was established by Clemens (1860), based on type species Eudarcia simulatricella Clemens, 1860. The genus is comprising 82 species in the world, which are wide spread and diverse throughout the Palaearctic region. Among them, nine species of Eudarcia are distributed in East Asia. In Korea four species of the genus Eudarcia have been reported to date. In the past, the subfamily Meessiinae was treated within the family Tineidae. Regier (2015) revised the addition of two families (Meessiidae, Dryadaulidae) to the superfamily Tineoidea through molecular analysis. In this study we described Eudarcia sp. as a new species, with illustration of adults and male genitalia.
