A specimen of Henricia was collected from the adjacent waters of Moseulpo, Jeju Island, Korea, using fishing nets. The specimen was identified as Henricia aspera Fisher, 1906, which belongs to the family Echinasteridae of the order Spinulosida. This species can be distinguished from other Henricia species by its broad arms (R/r=4.1), swollen arm base, three to seven short abactinal spines, and close-meshed formation of the actinal skeleton. This study has newly recorded H. aspera inhabiting the Korean fauna, bringing the total number of known Henricia species in Korea to 16. This study provides a description of the morphological characteristics of H. aspera with photographs of each part. Additionally, a table is presented that compares the morphological characteristics of H. aspera with closely related Henricia species.

Aquilonastra doranae, a newly recorded sea star, was collected from the southern coast of Jejudo Island by a trimix SCUBA diving survey in May 2021. The newly collected specimen is distinguished from a previously known Aquilonastra species in South Korea by having a fissiparous body form with six arms. Results of pairwise genetic distance analysis showed that the new specimen was identical or close to A. anomala from Hawaii (0.0%), Australia (3.1%), and Samoa (3.3%). However, morphological characteristics of the Korean Aquilonastra specimen corresponded with the original description of A. doranae, not that of A. anomala, including the number of inferomarginal spines, the absence of pedicellariae, and the inhabit locality. Thus, this study agrees with the original morphological study of A. doranae and presents this specimen as the first record of A. doranae in South Korea.

Fungi are cosmopolitan and they occupy diverse niches as consumers, producers, and decomposers. They play critical roles in the environment by enabling nutrient cycling and generating a plethora of secondary metabolites. This study aimed to identify and characterize fungal strains isolated from diverse sources on Muui Island, Republic of Korea. In 2023, a total of 86 fungal strains were collected and examined. Investigation of the morphological features and phylogenetic analyses of multiple barcode loci identified one putative novel species and two species previously unrecorded in the Republic of Korea: Colletotrichum sp., Colletotrichum guizhouense, and Fusarium brachygibbosum. This study provides a comprehensive description of their molecular phylogenies and morphological characteristics. These findings will contribute to the existing knowledge about fungal species in the Republic of Korea and future research on the fungal diversity on Muui Island.

Specimens of Bosmina longirostris collected from various freshwater habitats of 84 localities in South Korea from October 1981 to August 1997 were examined, and seasonal changes of the cladoceran populations in Late Kwangjuho from October 1995 to August 1977 were analysed. In this paper, B. longirostris in Korea was redescribed and figured, with a discussion of morphological characteristics. Some ecological features of the species were noted.

Two freshwater cyclopoid species including a new species are added to Korean copepod fauna: Ochridacyclops coreensis n. sp. and Itocyclops yezoensis (Ito, 1953). Both species were collected from the semi-subterranean waters like springs and wells. The present paper deals with the description of the new species and the systematic accounts on the two species, based on the morphological character comparison with the related congeners.

Two newly recorded small orb weavers, Araneus yasudai Tanikawa, 2001 and Neoscona flavida sp. nov., with characteristic epigynal scape belonging to Araneidae are described with measurements and morphological illustrations from Korea. Both species were collected with sweep net between shrubs and bushes in mountain forest and between reeds in reclaimed land, respectively.

Taxonomic study of the crustose lichen Porpidia was performed in this paper. Three species are described, including two recorded species and one new record: Porpidia macrocarpa (DC.) Hertel & A. J. Schwab. A description of each species is presented along with morphological, anatomic, and chemical characteristics. A key to the identification of species of Porpidia is also presented.

Many spiders belonging to Enoplognatha Pavesi, 1880 and Parasteatoda Archer, 1946 of Theridiidae were collected with sweep net between shrubs and bushes in the mountain forest during a survey of the mountain spider fauna. Among the spiders collected, male Enoplognatha gramineusa Zhu, 1998 and female Parasteatoda ryukyu (Yoshida 2000) were recognized as newly recorded spiders to Korean spider fauna. The present work describes these two spiders with measurements and morphological illustrations.

A spionid polychaete, Scolelepis (Scolelepis) kudenovi Hartmann-Schroder, 1981, is newly reported from Korean waters with description and illustration. Scolelepis (Scolelepis) kudenovi is characterized by a combination of the following morphological features: the notopodial setae are present on the setiger 1; the occipital tentacle is absent; the branchiae are partially fused to the notopodial postsetal lamellae; the notopodial and neuropodial hooded hooks are bidentate only; the notopodial hooded hooks are present on the posterior setigers. A key to Scolelepis species from Korean waters is provided in this paper.

Four new Korean records of the gammarid (Crustacea, Amphipoda), Grandidierella fasciata Ariyama, 1996; Moolapheonoides acutifalcatus Kobayashi and Ishimaru, 2005; Guernea terelamina Hirayama, 1985; and Gordonodius zelleri (Berge, Vader and Coleman, 1999) were reported from the Korean indigenous species survey project funded by the National Institute of Biological Resources (2014-2015). Each of these species is well accorded with the original description for the species except for some minor morphological differences. The genera Moolapheonoides Barnard, 1974 and Gordonodius Ariyama, 2011 are reported for the first time from Korea.
