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.

The bamboo katydid, Palaeoagraecia lutea (Matsumura et Shiraki, 1908) is newly reported in South Korea. Previously, the species was only known in Japan, but currently its occurrence is confirmed in the far southern locality of Hampyeong, Jeollanam-do province of Korean Peninsula. This katydid was collected using a light trap and sound tracing in the bamboo forest. It is regarded as a rare stenotopic species. The features of male Palaeoagraecia lutea are illustrated and discussed in terms of song characteristics, and a key is provided for the genus Palaeoagraecia. A new synonym is proposed: P. philippina (Karny, 1926)=P. globicerata (Vickery et Kevan, 1999) syn. nov.

A single specimen (244.2 mm in standard length) of Satyrichthys welchi was collected from Pohang in the southern East Sea of Korea in March 2021. This species is characterized by the following morphological combination: 4 lip barbels, 3 chin barbels, antrose spines on upper lateral low of posterior bony plate and equal parietal bones. S. welchi was morphologically similar to its congeneric species, S. laticeps, but is clearly distinguished in presence of dusky black spots on dorsal fin (present in S. welchi vs. absent in S. laticeps). We propose a new Korean name "Gi-JeomByeol-Seong-Dae" for the species S. welchi.

Two specimens of Chlorophthalmus nigromarginatus Kamohara, 1953 (51.02 mm, 66.04 mm in standard length) belonging to the family Chlorophthalmidae were collected on February 8, 2022 in the eastern Jeju-do Island, Korea using a bottom trawl. The species has the following morphological characteristics: snout length almost the same as orbit diameter, bump absent on predorsal, caudal fin with posterior black margin. C. nigromarginatus is morphologically very similar to C. acutifrons but can be distinguished by caudal fin with black margin (C. acutifrons has no black margin). Molecular analyses showed that our specimens almost matched with C. nigromarginatus according to mtDNA 16S rRNA sequences (99.8%). Therefore, we propose a new Korean name for C. nigromarginatus, "Geom-eun-kko-ri-pa-rang-nun-mae-tung-i".

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.

This work is a report about the first record of alcid species, Thick-billed Murre (Uria lomvia) in Korea. Four individuals of Thick-billed Murre captured by crab net were obtained in Deajin Port and near the Munam Port. three individuals of Thick-billed Murre searching food were observed at an area two miles away from Munam-Port. We describe characters of Thick-billed Murre with illustrations.

Desmotimmia mirabilis (Timm), a rarely known desmoscolecid nematode species, was discovered for the first time from the Yellow Sea off southwestern coast of Korea. This is the third record of the species, and the first report from the northwestern Pacific region. Redescription is prepared on the basis of a male specimen from South Korea.

Macromyzus woodwardiae(Takahashi, 1921) is recognized on Cyrdomium falcatum(L.f.) C. Presl (Dryopteridaceae), a htherto unknown host plant, from Jeju Island, Korea. Apterous viviparous female and alate viviparous female are described. This is the first record of genus Macromyzus in Korea.

A newly recorded species Orientomaera incisa Ariyama, 2020, belonging to the family Maeridae Krapp-Schickel, 2008, was collected from the sublittoral waters of the East Sea, Korea. Previously, only one species, O. brevispina (Kim and Kim, 1991), was reported in Korea. This species morphologically similar to O. brevispina however, the species can be easily distinguished from the O. brevispina by having two distinct teeth on palm of gnathopod 2. The newly recorded species is described and fully illustrated in the present study.
