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”.
