Abstract

A total of five individuals of azuma perchlet (63.3~73.2 mm SL), collected from Jeju-do Island between 2008 and 2024, were re-described for clarifying their taxonomic status. Our specimens were confirmed to be Zalanthias azumanus, not Zalanthias kelloggi, in having a wide red bar from the dorsal fin to 2~3 scale rows above the abdomen (vs. a red wedge-shaped marking on the upper half of the posterior body in Z. kelloggi) and a 3~5 scale-wide dark grey to red saddle on the caudal peduncle from the uppermost scale to 1~2 scales below the lateral line (vs. 5~6 scale-wide red saddle from the uppermost scale to the lateral line in Z. kelloggi). Therefore, we suggest that the scientific name of azuma perchlet in Korea be changed to Z. azumanus.
