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".

A single specimen of Chaetodon vagabundus Linnaeus, 1758 belonging to the family Chaetodontidae was collected on September 8, 2013 in Yerae-dong, Seogwipo-si, Jeju Island, Korea. The morphological characteristics of C. vagabundus are similar to C. auriga and C. auripes in having dark vertical stripes cross the eye, but differs from C. auriga, which has high dorsal fin extended between spine and soft rays without concavity and has blotch of circle in dorsal fin, and from C. auripes which has yellow body, big of eye proportion and a black stripe along the caudal peduncle during the immature stage. C. vagabundus has eye-like black spots on dorsal fin and black vertical stripe extended from the anterior dorsal soft ray to the middle of the anal fin along the caudal peduncle. Molecular analysis results showed that our specimen perfectly matched C. vagabundus in the mitochondrial DNA COI sequences. Therefore, we use the Korean name, "Hwang-jul-na-bi-go-gi" for C. vagabundus proposed by Kim et al. (2020).

A newly recorded chaetodontid species, Chaetodon speculum Cuvier, 1831 was collected in July, 2021 from Pohang, Korea. Its body color is yellow with black stripe across the eyes and a large spot occupying one fourth of the upper part of the body. C. speculum is very similar to congeneric species, C. zanzibarensis, but it can be distinguished by the size of the spot, shape of the lateral line, number of longitudinal line scales and geographic distribution. C. speculum is readily identified between post-larval stage and adult stage because of its similar external shape. Molecular analysis based on mitochondrial DNA COI sequences showed our specimen perfectly matched C. speculum. Therefore, we propose the new Korean name, "Heug-jeom-na-bi-go-gi" for C. speculum.

Seven species of the order Perciformes collected from coastal waters of Cheju Island, Korea were redescribed as new to Korean fish fauna. They are as follows: Girella melanichthys (Richardson) and Kyposus bigibbus Lacepede of the family Kyphosidae; Chaetodon wiebeli Kaup of Chaetodontidae; Istigobius campbelli (Jordan and Snyder) of Gobiidae; Gymnapogon japonicus Regan of Apogonidae; Parupeneus chrysoplueron (Temminck and Schlegel) of Mullidae; Nemipterus japonicus (Bloch) of Nemipteridae.
