A marine ulvalean species (Chlorophyta) was collected from Imgok, which is located on the eastern coast of Korea. This species is morphologically characterized by distromatic, filiform to strap compressed or tubular thallus. Many branches were found near the base, but lacked proliferations. Cells were longitudinally aligned in the younger part of the branch and were disordered in the older part of the branch. A cap-like parietal chloroplast with one or two pyrenoids was contained in each cell. In a phylogenetic tree based on ITS and rbcL sequences, this species was nested in the same clade as Ulva torta and U. clathratioides from Australia, but formed a sister clade to U. torta from Japan. However, the genetic divergence between them was included in an intraspecific variation range within Ulva. This finding suggests that U. clathratioides should be reduced to a synonym of U. torta. Accordingly, the Korean alga was identified as U. torta based on the morphological and molecular data. This investigation is the first record of U. torta in the Korean marine algal flora.

A single specimen of the stone cockscomb, Alectrias alectrolophus (Pallas, 1811) was collected from off Gangneung-si, East Sea, Korea. The present Korean specimen is characterized in having a dermal crest on dorsal median line of head, LXIII dorsal fin rays, I, 44 anal fin rays, 68 vertebrae, slender and flexible dorsal spines in its anterior parts, and scales on the posterior portion of body, and fused gill membranes forming a free fold across the isthmus. We report A. alectrolophus based on a single specimen collected from the Korean water as the first record from Korea.

Based on a single juvenile specimen (32.3 mm SL) collected from the northeastern coastal waters of Goseong, Gangwon-do, Nautichthys pribilovius was described as the first juvenile record from Korea. This juvenile fish is characterized by having entire body covered with close-set villous prickles, a blunt triangular ridge above orbit with a palmate cirrus, two blunt occipital projections, preopercle with four blunt spines, and a blackish bar below eye reaching lower margin of preopercle. Some morphometric characters related with growth were also discussed.

Two newly recorded carnivorous amphipod species, Anonyx gurjanovai Steele, 1986 and A. nugax (Phipps, 1774) belonging to the family Uristidae Hurley, 1963, were collected from the East Sea, Korea. Anonyx gurjanovai is included in the A. laticoxae group and is characterized by a concave palm of the propodus in gnathopod 1 and small posteroventral projection at epimeron 3. The other species, A. nugax, represents the A. nugax group and is distinguished from congeneric species based on the presence of a shorter and less acute projection on epimeron 3. There are 13 species of the A. nugax group recorded worldwide, but this is the first report on the presence of the A. nugax group in Korean waters. Previously, three species of the genus Anonyx had been reported in Korea, and through this study, we have added two newly recorded species. Both the newly recorded Anonyx species are illustrated and compared with the related species. A key to the Anonyx species in Korea is also provided.

The genus Microplitis (Braconidae: Microgastrinae) is reported for the first time from Korea. The Microplitis has often quite small hypopygium, very short ovipositor and rugose propodeum with large aleola. The genus contains 190 described species, among them 19 speceis were recorded in Korea. Microplitis varicolor was established by Viereck in 1917. The species is found as new to Korea in this study. Microplitis varicolor is endoparasitoid, especially attacking species of Noctuidae (Insecta: Lepidoptera) including pests of leguminous crop. In this study, diagnosis, photographs and host lists are included.

Dinoflagellates were investigated from the coastal waters of Korea. The total 100 thecate dinoflagellates taxa, comprising of 93 species five varieties and two forms were identified, which were attributed to four orders nine families, 13 genera in Korean coastal waters. 22 species, two varieties and two forms were new to Korean waters. Ceratium arcticum, C. longirostrum, C. praelongum, C. tripos var. ponticum, Gonyaulax jollifei, G. pavillardii, Protoperidinium cassum cassum, P. conicum f. asamushi, P. depressum var. parallelum, P. elegans f. granulatum, P. globifera, P. incognitum, P. majus, P. mite, P. obtusum, P. pallidum daedalum, P. parvum, P. perplexum, P. pyriforme pyriforme, P. pyrum, P. sphaeroides, P. subsphericum, P. valgus, P. venustum, Diplopsalopsis orbicularis, Gotoius abei were new record species for Korea.

Hypsicera has been reported six species from South Korea. In this study, we reviewed 13 species of South Korean Hypsicera including seven newly recorded species from South Korea. Female of H. brevicornis and H. nigribasis are reported for the first time from South Korea since first record. Additionally, H. incarinata and H. yoshimoboi are reported new to China. We provide diagnoses of six newly recorded species and descriptions of two new females. We also provide photographs of key characters of seven newly recorded species and a key to 13 species of South Korean Hypsicera.

Using the criteria of previous study, we analyzed the morphological characters of 66 specimens of the Sebastes pachycephalus complex collected from Korea between 2008 and 2013. As a result, the 37 specimens were identified as Sebastes nudus, and the remaining specimens as Sebastes pachycephalus. Sebastes nudus is characterized by the absence of scales below the base of the dorsal fin spines; the absence of dark spots on the dorsal, anal, and caudal fins; and the presence of distinct yellow or brownish-red markings on the dorsum (when fresh). The most similar species S. pachycephalus differs from S. nudus in having minute scales below the base of the dorsal fin spines. We propose the new Korean name "Hwang-jeom-gae-bol-rak" for S. nudus, and redescribe S. pachycephalus.

One of bryozoans collected from the subtidal zone of Manjae Island on Aug. 23, 1988 was identified. Parasmittina delicatula (Busk, 1884) turned out to be new to the Korean fauna. Therefore, twelve bryozoan species are reported from Manjae Island so far. Ten species including the present one among them were recorded only from the Pacific Ocean. They consisted of four tropical, three cold temperate and four endemic species to Korea and Japan. It is quite probable that Manjae Island, which is influenced by both warm and cold water currents, seems to be unique and significant area in terms of marine zoogeography.

A single specimen (91.5 cm standard length) of the salmonid species, Oncorhynchus tshawytscha (Walbaum, 1792) was collected on April 19, 2022 in Sokcho-si, Gangwon-do, Korea. O. tshawytscha has the following morphological characteristics: base of lower jaw teeth is black, black spots are scattered on the dorsal section of body, and the edge of caudal fin is black. Although the species is morphologically similar to Oncorhynchus kisutch, O. tshawytscha differs from it in having black spots on the caudal fin. Molecular analysis results based on mitochondrial cytochrome c oxidase subunit I (COI) sequences showed that our specimen perfectly matched with the COI sequences of O. tshawytscha registered at the NCBI. Therefore, we suggest the new Korean name 'Wang-yeon-eo' for O. tshawytscha.
