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.

A single juvenile pomacentrid specimen (5.9 mm standard length) was collected from the Korea Strait in October 2010. The specimen is characterized by punctate-stellate melanophores scattered on the operculum and dorso-ventral region in front of the caudal peduncle, the lack of melanophores on the posterior end of the anal fin base, the presence of 14 spines and 14 soft rays on the dorsal fin, and the presence of 2 spines and 12 soft rays on the anal fin. A molecular analysis based on mitochondrial DNA 16S rRNA sequences showed that this specimen is closely related to adult Chromis mirationis (d = 0.002), but that it differs from Chromis notata (d = 0.017). Juvenile C. mirationis differ from juvenile C. notata in having no melanophores on the posterior end of the anal fin base. We propose a new Korean name, "tti-ja-ri-dom" for C. mirationis.

Based on a single juvenile specimen (20.7 mm SL) collected from Jeju Island, Apogon semiornatus was described as a new Korean record. The species is characterized by having VI-I, 9 dorsal fin rays, 12 pectoral fin rays; II, 8 anal fin rays and two blackish oblique bands on yellowish red body. A new Korean name, "Geom-eun-du-jul-bulg-eun-dong-gal-dom", is proposed.

In April 2019, a single Peristediidae juvenile (14.1 mm SL) was collected from the waters off of Jeju-do Island, Korea. DNA barcoding identified the juvenile as Peristedion liorhynchus, an unrecorded species in Korea. P. liorhynchus has eight dorsal fin spines, 22 dorsal and 19 anal fin rays, and a long third pectoral fin ray that passes through the middle of the tail at the juvenile stage. Juvenile also have large heads, extensive head spination, and serrated edges on the ocular and parietal spines. This is the first record of P. liorhynchus in Korea; therefore, we propose the new Korean name, "Nam-bang-hwang-seong-dae".

A single juvenile malacanthid specimen (Hoplolatilus chlupatyi) was collected from the South Sea of Korea and identified by DNA barcoding. This species is readily distinguished from other malacanthid species in having well developed rostral spine and elongated spines in the posttemporal and preopercle. A molecular analysis based on mitochondrial DNA COI sequences showed that this species is matched to adult H. chlupatyi (genetic distance = 0.005). Therefore, this is the first record of H. chlupatyi in Korea. We propose new Korean names, "Mu-ji-gae-og-dom-sog" for the genus Hoplolatilus and "Mu-ji-gae-og-dom" for the species H. chlupatyi.

Based on four juvenile specimens of Lutjanus collected from the southern coast of Jeju Island, three species, L. argentimaculatus, L. fulviflamma, and L. quinquelineatus, are described as the first record from Korea. The first species is easily differentiated from other lutjanid juveniles by distinct coloring of the dorsal, pelvic, and anal fins as well as two blue lines below the eye; the second species is characterized by having six yellowish brown stripes below the lateral line and a black spot on the side; the third species is identified by five longitudinal blue stripes and a black spot on the side when fresh. The new Korean names "Bul-geun-tung-dom," "Yuk-seon-jeomtung-dom," and "O-seon-tung-dom" are proposed for L. argentimaculatus, L. fulviflamma, and L. quinquelineatus, respectively.

A single juvenile of the jawfish Stalix toyoshio (24.0 mm standard length) was collected from the South Sea of Korea at a depth of 135 m during box-corer sampling. The specimen was characterized by the absence of stripes on both the body and vertical fins, well-developed cephalic pore systems, yellowish body and fins, six transversely-forked dorsal fin spines, and five mandibular pores. Here, we describe the specimen, which represents the first record of S. toyoshio from Korea and the second record from the northwestern Pacific.

A single specimen of a juvenile Stethojulis trilineata was first collected from the coastal waters of Ulsan, Korea, in October 2012. This species is characterized by IX dorsal fin spines, 26 lateral line scales, 25 vertebrae, dark spots between the 10th and 11th dorsal fin rays, and a caudal peduncle region. The new Korean name proposed is "Se-jul-mu-ji-gae-nol-rae-gi" for S. trilineata.

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.

A juvenile of the slender fangjaw, Sigmops gracilis G$\ddot{u}$nther, 1878 (Stomiiformes: Gonostomatidae) was collected from Jeju Island, Korea, and identified by DNA barcoding. This species is characterized by its large curved mouth and the presence of 11 dorsal fin rays and 28 anal fin rays. During the juvenile stage, the species is distinguished from other gonostomatid species by the position of the origin of the dorsal fin, which is located at the 7th-8th ray of the anal fin. The Korean name "Sol-ni-ael-tung-i" is proposed for this species.
