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.

Pseudolithoderma subextensum is a crustose brown algal species in the family Lithodermataceae and order Sphacelariales. This species is distributed in several regions across the world including, Europe, Western Atlantic, Middle East and Asia (Hong Kong and Japan). Recent floristic surveys along the Korean coastal shores have revealed new records of encrusting brown algae. In this study, we report P. subextensum as a new record from Korea. Morpho-anatomical and molecular studies on Ralfsia-like specimens from Korea identified some of them as P. subextensum. Pseudolithoderma subextensum is characterized by dark chestnut brown crust with a hypothallial basal layer and erect perithallial filaments, tufts of hairs occasionally arising from the basal layer, several discoid shaped chloroplasts per cell, plurangia arising terminally on erect filaments and without sterile cells, and unangia arising terminally on erect filaments, elongated cylindrical and without paraphyses. Phylogenetic analyses based on COI-5P (545bp) reveal that P. subextensum are nested within Lithodermataceae and forms the same clade with P. roscoffense. The genetic divergences for COI-5P between them is 24.5%.

This is the first report of Pterygotrigla multiocellata from the family Triglidae, collected in Korea. The specimen (314 mm in standard length) was caught in a gill net in the coastal waters of Jeju Island on 11 February 2010. This species is characterized by the following morphological traits: head large and triangular, bony plates absent along the base of the second dorsal fin, antrorse rostral spine long, and cleithral spine long. We suggest a new Korean name, "Gin-ppul-mit-seong-dae" for P. multiocellata.

Seventeen specimens (29.1~50.7 mm SL) of the starry goby, Asterropteryx semipunctata, were collected from the southern coast of Jeju Island, Korea, and described as the first record from Korea. The species is characterized by having separated pelvic fins, five to eight short spines on posterior margin of preopercle, and numerous blue spots on head, body and unpaired fins except for first dorsal when fresh. We proposed a new Korean name, 'Cheong-byeol-mang-duk', for the species.
