Five specimens (839 - 1280 mm TL, Total length) of the dusky shark Carcharhinus obscurus, belonging to the family Carcharhinidae, were collected from the waters off Jejudo Island, Sinan, Namhae, Busan and Gangneung, Korea, during 2010-2019. Carcharhinus obscurus was similar to Carcharhinus brachyurus but was distinguished by the interdorsal ridge (present in C. obscurus vs. absent in C. brachyurus) and the shape of upper jaw teeth (broad in C. obscurus vs. narrow in C. brachyurus). In addition, 479 base-pair sequences in the mitochondrial DNA cytochrome c oxidase subunit I (COI) of our two specimens corresponded to those of C. obscurus (genetic distance, 0.000-0.003), but clearly distinguished from those of the Korean C. brachyurus (genetic distance, 0.03). We adopted the Korean name "Heuk-sang-eo" for Carcharhinus obscurus, after Kim and Ryu (2017).

Two specimens of Scomberoides tol (99.0 mm and 124.5 mm in total length), belonging to the family Carangidae, order Perciformes were collected from Korean waters using a gape net with wings and a hand net between 2014 and 2017. These specimens are characterized by having the origin of the soft-rayed portion of the dorsal fin just above the origin of the soft-rayed portion of the anal fin, dorsal spines not connected by fin membranes and posterior end of the maxilla and upper jaw not extending beyond the posterior margin of the eye. A comparison of mitochondrial DNA cytochrome c oxidase subunit I sequences indicated that these specimens matched Scomberoides tol (K2P distance, d = 0.002), but differed from other Scomberoides species (6.9-9.1%). This is the first reliable report of Scomberoides tol from Korea.

Three juvenile specimens (40.7~58.4 mm SL) of orbicular batfish, Platax orbicularis were collected from the coastal waters of Jeju Island, and described as the first record from Korea. These specimens were characterized by having a diamond body shape with triangular dorsal and anal fins with V, 35~37 and III, 26~27 rays, respectively. The new Korean name of 'nam-bang-je-bi-hwal-chi' is proposed for the species.

Meloidogyne marylandi Jepson & Golden, 1987 is described from Zoysia grass collected in Cheonan, Korea. The nematode did not produce galls, and females were generally surrounded by a massive egg sac. Perineal patterns of female were a high to rounded arch with shoulders, wavy striae usually forming a rough. Vulva and anus were sunken. Second-stage juvenile body length was 390.3 $\mu\textrm{m}$ (290-430), tail length 55.1 $\mu\textrm{m}$ (49-59) and lateral field with 4 incisures. Male stylet length was 18.1 $\mu\textrm{m}$ (15-24), spicules length 26.2 $\mu\textrm{m}$ (23-29) and lateral field with 4-5 incisures.

A single leptocephalus specimen of Albula glossodonta belonging to the family Albulidae under the order Albuliformes, was collected from the southern sea of Korea in May 21, 2019. This species is distinguished from A. vulpes in the number of melanophores at the base of the caudal fin. In addition, our specimen was readily distinguished from A. argentea in having no melanophores on the operculum, at the base of the dorsal fin and in front of the pectoral fin. Also it was well distinguished from A. gilberti in having no melanophores on the operculum, in front of the pectoral fin and on the lateral body. A molecular analysis based on 467 bp sequences of the mitochondrial DNA 16S rRNA shows that the leptocephalus is well matched to A. glossodonta adult (K2P distance=0.002). We report the first occurrence of A. glossodonta leptocephalus in the Korean waters, and propose it's new Korean name, "Nam-bang-yeoeul-myeol".

We collected a specimen of Heniochus diphreutes Jordan, 1903 belonging to the family Chaetodontidae on December 26, 2020 in Pohang-si, Gyeongsangbuk-do, using the set net. Although, H. diphreutes is morphologically very similar to Heniochus acuminatus, it can be distinguished from the latter based on the number of dorsal fin spines, mostly 12 in H. diphreutes vs 11 in H. acuminatus, and the percentage of snout length in head length, which is less than 12% in H. diphreutes vs more than 13% in H. acuminatus. Compared to H. acuminatus, H. diphreutes has a shorter snout, two-three rows of teeth, convex ventral profile of the head, more angular anal fins, and a black pattern extending to the longest soft rays on the posterior part of the anal fin. Molecular analyses showed that our specimen perfectly matched H. diphreutes based on mtDNA COI sequences data. We propose a new Korean name for H. diphreutes, "Jjal-beun-ib-du-dong-ga-li-dom".

Two juvenile (9.48 and 10.11 mm in standard length) specimens of the lanternfish Notoscopelus japonicus, belonging to the family Myctophidae, were collected from the waters around Busan and Jeju Island in February 2017. This species is characterized by having melanophores along the dorsal side of the body and one photophore (PO5) in front of the pelvic fin. It is distinguished from Benthosema pterotum in having many melanophores on the dorsal side and a single photophore (PO5) on the trunk. N. japonicus is also distinguished from its congeneric N. resplendens and N. caudispinosus in having no melanophores at the base of the anal fin. Analyzing 521 base pairs of the 16S rRNA sequence, the specimens were identical to N. japonicus adults from Japan (K2P distance <0.004). This is the first record of N. japonicus in Korea, and we propose a new Korean name "Deung-jum-saet-bi-neul-chi" for this species.

For the first time, a single specimen (68.47 mm in total length) of Lumpenopsis pavlenkoi Soldatov, 1916 belonging to the family Stichaeidae was collected from the northernmost area of the eastern coast of Korea (Gosung, Gangwon Province) in April, 2020, using square net (1.0 m width, 0.3 m height, 2.0 mm mesh size). This species is characterized by elongated and compressed body, absence of lateral line and cirri on head, presence of scales on cheek, dorsal fin with only 50 spines, anal fin with 2 spines and 30 soft rays, and separated operculum and isthmus. The body is yellowish with 7 saddles. The new Korean name "Kko-ma-be-do-ra-chi-sog" is proposed for the genus Lumpenopsis, and "Deung-jeom-kko-ma-be-do-ra-chi" is proposed for the species L. pavlenkoi.

Unidentified postflexion larva (18.57 mm in standard length, SL), belonging to the family Synodontidae was collected from Jeju Island, Korea, in November 2019. Molecular analysis revealed that the unidentified larva was identical to Synodus kaianus adults in mtDNA cytochrome c oxidase subunit I region (Kimura-2-parameter distance, d= 0.006), and was different from the close species S. macrops (d=0.220). The postflexion larva of S. kaianus has the following morphological features: regularly distributed seven peritoneal pigment spots along the alimentary canal; and, intensively distributed stellate melanophores at the middle of the base of caudal fin and behind the last anal fin ray. The postflexion larva of S. kaianus differed from that of S. macrops in snout length and size of peritoneal pigment spots. This is the first record of S. kaianus in Korea, and we suggest the Korean name "Ka-i-ya-kkoch-dong-myeol" for S. kaianus, according to Lee et al. (1999).
