  • Parasesarma bidens(De Haan, 1835) has been designated as a marine protected species by the Act on conservation and management of marine ecosystems. This crab has been recorded only from Jeju-do and Geomun-do, Republic of Korea. In this study, we describe for the first time the mitochondrial cytochrome c oxidase subunit I(COI) sequences of P. bidens. The intra-specific genetic distance among the Korean populations and between the Korean and Chinese populations ranged from 0% to 0.9% and 1.9% to 2.7%, respectively. The inter-specific genetic distances among the four Parasesarma species ranged from 10.9% to 12.8%. The finding of this study will be helpful to better describe P. bidens using COI DNA barcodes and can be used as basic data for their restoration and conservation research.

  • Six new species of two genera Dysidea and Pleraplysilla (Demospongiae: Dictyoceratida: Dysideidae) are described from Jejudo Island, Dokdo Island and Guryongpo, Korea. Among them, five new species of the genus Dysidea are compared with other reported species in fibres structure, cored detritus and fibres arrangement. Dysidea niveus n. sp. is characterized by thin collagenous plate-like fibres. Dysidea dokdoensis n. sp. is similar to D. geomunensis Kim et al., 2020 in skeletal structure, but differs in length of surface conules. Dysidea hydra n. sp. is similar to D. mureungensis Kim et al., 2020 at the surface, but differs in fibres cored with spicules. Dysidea sabulum n. sp. is similar to D. glavea Kim et al., 2020 in cored large sands in fibres, but differs in having numerous large sands cored in fibres throughout the sponge. Dysidea hirsuta n. sp. is unique, only surface fibres cored with large sands but not in choanosome. A new species of genus Pleraplysilla, P. flabellum n. sp. is compared with seven other reported species. This new species is not encrusting but has a thick flabellate shape.

  • Herein, we report a new record of Notodontidae moth, Neodrymonia marginalis (Matsumura) in Korea. This species is characterized by grayish forewing that shows thick dark grayish band between basal and antemedial line, smooth postmedial line costally with blackish crescent line, dark grayish subtermen with dark brownish thick band costally, and whitish and black dot shaped discal dot. The female genitalia can be distinguished by the broad, plate-shaped postvaginalis, strongly sclerotized ductus dursae with three long spike shaped and several small spike shaped processes, and large, ovate corpus bursae with a large fan-shaped plate signum. Neodrymonia marginalis can be distinguished from N. deliana by the shape and color of the costal part of postmedial line and subtermen of forewing. The female genitalia of N. marginalis can be distinguished from those of N. deliana by the rectangular postvaginalis and more spike like processes of the anterior of ductus bursae. Up to now, four species of Neodrymonia are recorded in Korea: N. delia (Leech, 1889), N. coreana Matsumura, 1922, N. deliana Gaede, 1933, and Neodrymonia marginalis.

  • From a moss sample, we isolated and identified Notohymena gangwonensis Kim et al., 2019 based on morphological and molecular data. The moss and type population has completely identical 18S rRNA (nuclear small subunit ribosomal RNA) gene sequences and both are highly similar in morphological and morphometric attributes, except for the diameter and arrangement of the cortical granules. Thus, we reexamined the type materials(i.e., micrographs and gDNA) and resulted in finding mistakes made by the authors of the species. Based on these data and supporting materials newly obtained (i.e., internal transcribed spacer [ITS] 1, ITS2, 5.8S, and partial 28S rDNA sequences, and scanning electron micrographs), we provide improved diagnosis of the species to clarify its identity. In addition, a key for Notohymena species is provided.

  • This paper reports four species of Erebidae from the southern part of Korea: two Boletobiinae, Honeyania ragusana (Freyer, 1845), Enispa masuii Sugi, 1982, one Hermininae, Adrapsa ablualis Walker, 1859, and one Arctiinae, Stictane rectilinea (Snellen, 1879). Honeyania ragusana can be distinguished by the following: a blackish dot on the apex of the forewing with strongly curved medial lines, a long slender uncus and a strongly distally bifurcated valva with a large distally expanded costa and a thumb-shaped process of sacculus on the male genitalia as well as a sclerotized antrum, strongly tapered ductus bursae, and large corpus bursae on the female genitalia. Enispa masuii, a lichen feeder, can be distinguished by the whitish medial lines of the grayish fore- and hindwings, and a pair of rounded ball-shaped lamella antevaginalis, long, sclerotized ductus bursae, and pear-shaped corpus bursae without signum of the female genitalia. Adrapsa ablualis can be distinguished by the whitish medial lines of the fore- and hindwings and large medial process of the costa and dentate distal margin of the valva of the male genitalia. Stictane rectilinea can be distinguished by the broad dark grayish medial band of the forewing and the long knife-shaped valva with a strongly hooked process on the distal part of the sacculus of the male genitalia.

  • Isaacsicalanus paucisetus Fleminger, 1983, a monotypic species of the family Spinocalanidae Vervoort, 1951, was first reported from a hydrothermal vent field in the East Pacific Rise off the mouth of the Gulf of California. The mitochondrial cytochrome oxidase I(mtCOI) DNA barcodes are considered a useful tool to assist traditional taxonomy and species discrimination in calanoid copepods. However, the mtCOI DNA barcodes of I. paucisetus have not been reported due to the species rarity and the difficulty of sampling. In this study, we firstly determined the mtCOI DNA barcodes of the I. paucisetus newly collected from a hydrothermal vent in the North Fiji Basin of the southwestern Pacific. All mtCOI DNA barcodes of I. paucisetus were identical and intraspecies variations of spinocalanid species were 0.0-3.0%. Interspecies and intergeneric variations were 13.4-25.2% and 16.7-24.1%, respectively. The DNA barcodes of I. paucisetus obtained in the present study would be helpful for understanding taxonomic relationships of widespread spinocalanid species.

  • 한국에 서식하는 A. chinensis의 골학적 특정을 조사하기 위하여 본 종이 속하 는 황어아과 어류와 가장 가까운 강준치아과 어류 수종의 골격들과 비교검토한 결과 등지느러미와 뒷지느러미의 기조수가 같고, symphyseal knob가 없으며dermosphenotic과 안상골이 접촉되어 있지 않고, 수염이 없는 점 등은 황어아과의 다른 어류들과 일치하였고, 복부 용골상 융기연과 전이골의 trigemino- facial nerve foramen이 2개인 점은 강준치아과 어류의 특정과 일치하였다. 그퍼나 상사골의 형태.4개의 안하골, 하미축골이 5-6개. 양안간격의 비가 57-60%, ex-trascapular가 없고, 선측이 불온전하고, 봄비 극히 왜소한 점 등은 오직 A. chi-nensis만이 특이하게 소유하고 있는 점으로 보아 본 종은 지금까지 보고되지 않은 새로운 아과에 해당되는 어류 분류군이 될 가능성도 있다. 그러나 이 점은 앞으로 보다 자세한 전기영동 분석과 수리분류학적 그리고 기타 형태학적 연구로 면밀히 검토되어야 할 것으로 믿는다.
