The perciform suborder Labroidei comprising six families (Cichlidae, Embiotocidae, Pomacentridae, Labridae, Odacidae, and Scaridae) are characterized by having the specialized pharyngeal jaws for food processing, i.e., united fifth ceratobranchials and upper pharyngeal jaw articulating with the basicranium via diarthroses (Stiassny and Jensen, 1987). They usually inhabit in the most tropical and subtropical seas and comprise about 235 genera and roughly 2,274 species worldwide (Nelson, 2006). Concerning the Korean labroid fishes, Mori (1952) had listed 18 genera and 26 species belong to four families in his check list of Korean fishes since Jordan and Metz (1913) firstly reported six genera and seven species in only two families (Embiotocidae and Labridae). Chyung (1977) added two species, Tilapia mossambica and Cirrhilabrus temmincki, to Mori’s list and also classified them into three suborders, i.e., Embiotocina (containing only Embiotocidae), Pomacentrina (Cichlidae and Pomacentridae), and Labrina (Labridae and Scaridae). Subsequently, Lee and Kim (1996) reviewed the Korean labroidfishes taxonomically resulting in 22 genera and 32 species in five families with some taxonomical modifications including a new Korean record. It is remarkable to be added many new Korean recordsto the pomacentrids or the labrids for recent 10 years (Koh et al., 1995; Yoo et al., 1995; Koh et al., 1997; Myoung, 1997; Choi and Kim, 2000; Choi et al., 2002; Kim and Go, 2003). Recently, Kim et al. (2005) briefly described all members of the Korean Labroidei with a color photograph or a figure, recognizing 27 genera and 42 species in five families. In the present study, the current taxonomical status of the Korean labroid fishes including distributional features is summarized based both on specimens collected from the Korean waters and on literature survey to provide bio-information of the Korean native fish species. As a result, the Korean labroid fishes totally consist of 27 genera and 44 species in five families, that is, Cichlidae (1 species), Embiotocidae (3), Pomacentridae (15), Labridae (22), and Scaridae (2). They distributed mainly in the coastal waters of the South Sea, Korea, however, most pomacentrids or labrids occur in the coastal waters of Jeju Island only, although some species were observed in their larval or juvenile stages only from coastal waters of the island. Interestingly, several species are expanding their distribution north to Ulreung and Dok islands in the East Sea, Korea lately.

The single postlarval specimen (7.53 mm in standard length) of Thalassoma quinquevittatum (Lay & Bennett, 1839), belongs to the family Labridae, was collected by a bongo net from the southern coastal waters of Jeju-do Island, Korea in November 2020. T. quinquevittatum has a deeply curved dorsal contour before the dorsal fin, the oval eyes, and no melanophores throughout the body. While T. amblycephalum has a slightly curved dorsal contour before the center of the dorsal fin, the circular eyes, and few melanophores on the body. A molecular analysis based on 548 base pairs sequences in the mitochondrial DNA cytochrome c oxidase subunit I region shows that the specimen was closely matched to adult T. quinquevittatum (K2P distance=0.002-0.005). We report the first record of T. quinquevittatum in Korean waters, and suggest its new Korean name "Da-seot-jul-saek-dong-nol-rae-gi".

The author has collected as many as 35 species belonging to 25 genera in 18 families by trap net in the fishing ground of Chromis notatus along Seogwipo coast in Jeju-do. Among 35 species included are 6 species of Labridae, 4 species of Scorpaenidae, 3 species of Pomacentridae, and 3 species of Monacanthidae. In regard to the amount of catch, more than $90\%$ are Chromis natatus which are mainly caught within the depth of $15\~25m$, and the rest are largely Apogon semilineatus and those belonging to Labridae. ; Some ornamental fishes, subtropical fishes and some rare species are also collected.

One specimen of the percophid fish, Pteropsaron evolans Jordan and Snyder and two specimens of the labrid fish, Xyrichtys verrens (Jordan and Evermann) were newly collected from Jeju Island of Korea. P. evolans is characterized by having one pair of spines at snout, cheek without scales, and elongated first dorsal fin in male. X. verrens is easily distinguished by having tip of pectoral fin black, many rows of scales on cheek, and an elongated pelvic fin. We describe as new to Korean fish fauna and propose new Korean names, "Sil-nun-tung-i" for the former and "Jang-mi-ok-du-nol-rae-gi" for the latter.

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.

The lateral line scales of the Labridae fish are ellipse, pentagoanl, or hexagonal, but most of them are the hexagonal type. Those of Ciarrhilabrus temminckii, ellipse, Xyrichtys dea, Choerodon azurio, Semicossyphus reticulatus and Bodianus oxycephalus are pentagonal. The most complex species are Choerodon azurio which is pentagonal, but similar tohexagonal, and Pteragogus flagellifera which is hexagonal, but similar to pentagonal type. The sizes of sensory tubes for the Labroides dimidiatus and Cheilio inermis were larger than the other group and Xyrichtys dea had most narrow one. These varied sizes of sensory tube indicate that development of sensory tube is deeply connected with inhabitation.

The toxonomic revision of the suborder Labroidei was made based on the specimens collected from the coasts of Korean Peninsula from 1988 to 1996. The fishes of this suborder in Korea are composed 32 species belonging to 22 genera and five families of Pomacentridae, Cichlidae, Embiotocidae, Labridae, and Scaridae. And the keys to species, genera and families are provided with redescriptions and collection data. Among them the specimens of 21 species were collected and Ditrema viridis of family Embiotocidae was the first record from the coast of Wando-gun, Chollanam-do, Korea. Most species of the suborder Labroidei of Korea were mainly distributed in the coast of Cheju Island and South coast influenced by the warm Kuroshio Current.

Karyotypic analysis was performed for Labridae fishes, Pseudolabrus japonicus, Halicho eres tenuispinis, H. poecilopterus and Pteragogus flagellifera from coastal area of Cheju Island in Korea. The chromosome numbers(Karyotypes) were 42(4M+24SM+14ST, A), 48(2M+2SM+44ST, A), 48(2M+46ST, A) and 42(4M+24SM+14ST, A) in P. japonicus, H. tenuispinis, H. poecilopterus and P. flagellifera, respectively. Heteromorphic sex chromosome was not found in both sexes of each Labridae fishes. However, large satellites were located on the largest subtelocentrics in P. japonicus and P. flagellifera.

Protogyny is known in 14 families of fishes, 11 of which inhabit coral reef areas. The wrasses (Labridae) comprise a large and well-known family of coral reef fishes that exhibit sequential hermaphroditism. The purpose of the present investigation was to examine the allomeoic growth patterns of several morphometric characteristics, including those used commonly to distinguish sexes of cocktail wrasse, pteragogus aurigarius (Richardson) and to assess their effectiveness in discriminating between males and females.

Parabrachiella bera (Yamaguti, 1939) is redescribed based on newly collected material from multicolorfin rainbowfish, Parajulis poecilopterus, landed at Wando fishery port on the southern coast of Korea. Although some differences were observed between the original description and the specimens examined in this study, these differences do not warrant a change in the taxonomic status of this species. Parabrachiella bera bears some resemblance to Parabrachiella incurva Shiino, 1956, but differs from it in details of the trunk and genital processes.
