ABSTRACT

A single larval specimen (7.07 mm SL) was collected off Jeju Island, Korea in May 2024. This species is characterized by a fused head with bony plate, expanded posttemporal and supracleithrum with large laminar plates, posteriorly directed spines on preopercle, and a wavy-shaped dorsal fin in the tholichthys stage. The specimen was identified as Chaetodon citrinellus using counts and mtDNA COI sequences. Our specimen perfectly matched an adult voucher specimen from Japan. Tholichthys stage of C. citrinellus represents the first documented case worldwide. In this study, we propose a new Korean name, “jag-eun-jeom-na-bi-go-gi” based on speckled spots along the lateral side of the body in the adult stage.
