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.
