지금까지 한국의 긴나무좀아과에는 4속 6종이 알려져 있다. 본 연구에서는 3종의 한국 미기록종을 다음과 같이 보고한다: 배외긴뿔나무좀 (Crossotarsus niponicus (Blandford, 1894)), 이승악긴나무좀(Platypus contaminatus (Blandford, 1894)), 닮은긴나무좀(Platypus quercivorus (Murayama, 1925)).

We report Ptycholaimellus ocellatus Huang and Wang, 2011, a free-living marine nematode of the family Chromadoridae Filipjev, 1917, as a newly recorded species in Korea. The specimen was collected from intertidal sediment habitats along the southern coast of Korea. Ptycholaimellus ocellatus is characterized by a distinct set of morphological features, including an abruptly tapered cervical region, the presence of ocelli, a transversely striated cuticle with lateral differentiation marked by two prominent longitudinal rows of dots, a large ampulla within a voluminous ventral gland, and two pharyngeal bulbs. This study provides the first taxonomic report of the genus Ptycholaimellus in Korean waters with differential interference contrast (DIC) and scanning electron microscopy (SEM) micrographs.

Morphological analyses of two newly recorded sea star species, Henricia exigua Hayashi, 1940 and Henricia tumida Verrill, 1909, of genus Henricia collected from Dongsan Harbor in the East Sea and Chuja-do, Jeju, Korea, respectively, were carried out. Henricia exigua could be characterized by an irregular arrangement of abactinal plates with adambulacral armature comprised of 10-13 spinelets. Henricia tumida has a short arm (R/r=4.0-4.2) with abactinal paxillae scattered and 4-8 abactinal spinelets with adambulacral spines having 4-6 spinelets. This study provides the first report of H. exigua and H. tumida in the Korean fauna along with detailed morphological description with their key characteristics.

Hitherto, 37 species in 10 genera under 4 subfamilies have been known from the Korean Peninsula. In this study, three newly recorded species are reported for the first time from Korea: Conops ceriaeformis ussuriensis Zimina, 1974, Physocephala pielina Chen, 1939, and Myopa picta Panzer, 1797. Morphological diagnoses and illustrations of these species are presented. Additionally, a key to all species of Conopidae from Korea is also provided.

Moth flies (Diptera: Psychodidae) are small fuzzy flies found in diverse habitats from mountains to urban areas, even in your house. Approximately 3,000 species among 6 subfamilies are recorded worldwide. However, in Korea, only 10 species from 3 genera of the subfamily Psychodinae have been recorded, including 8 species from North Korea. A preliminary study on moth flies in Korea was conducted using specimens collected via malaise traps and by hands from various locations in South Korea. As a result, Brunettia lungjingensis, Thornburghiella decoricornis, Philosepedon monstruosus and our friendly but unrecorded, Clogmia albipunctata are newly described in Korea. Brief descriptions, photographs, and illustrations of these four species are provided.

The genus Argyresthia Hübner, [1825] of the family Argyresthiidae is known to comprise over 150 species worldwide. Among them, more than 70 species are recognized in the Palearctic region. The Korean fauna of the genus Argyresthia includes 11 described species to date. In this study, we report three species of the genus Argyresthia for the first time in Korea: A. brockeella (Hübner, [1813]), A. longalbella Liu, Wang & Li, 2017, and A. mala Liu, Wang & Li, 2017. All available information, images of adults and genitalia for species are provided.

This study reports the first records of four coleophorids, namely Coleophora kamchatica (Anikin, 1999), C. lativittella Erschoff, 1877, C. levantis Baldizzone & Oku, 1988, and C. citrarga Meyrick, 1934, in Korea. Additionally, the presence of two species, C. montaniella Oku & Kusunoki, 2018, and C. artemisicolella Bruand, 1855, in Korea has been overlooked in the previous checklist of the family Coleophoridae in Korea, despite there being evidence of their existence. Consequently, with these additions, the total number of known species in Korea has been confirmed to be 42, expanding from the previously identified 36 species. Diagnostic characteristics and photographs of adults and genitalia for the four newly recorded species are provided, along with evidence supporting the presence of the two overlooked species in Korea.

The genus Paragabara is recognized as a member of the subfamily Boletobiinae, with six species in the Eastern Palaearctic. In Korea, three species of this genus are known. Konoenko et al. (2010) designated a lectotype for P. flavomacula (Oberthür, 1880) and described a new species, P. curvicornuta. In this study, the misidentification of the Korean P. flavomacula as P. curvicornuta has been corrected. Additionally, one newly recorded species, P. curvicornuta, is reported from Korea. In total, four Paragabara species are recognized in Korea. All available information, images of adults, a checklist, and male and female genitalia, etc., are provided.

Henricia specimens were collected using a dual approach of trimix scuba diving and fishing nets. This inclusive collection encompasses the discovery of two species highlighted in this study and introduces and provides comprehensive descriptions for Henricia kinkasana and Henricia longispina aleutica. The descriptions offered in this study were derived from the thorough examinations of external morphological characteristics. The documentation provides detailed insight into key traits related to the abactinal and actinal skeletons and spines of these newly recorded species in Korea. This comprehensive examination contributes to our understanding of the distinct morphological characteristics defining each species within the genus Henricia.
