Abstract

Using the criteria of previous study, we analyzed the morphological characters of 66 specimens of the Sebastes pachycephalus complex collected from Korea between 2008 and 2013. As a result, the 37 specimens were identified as Sebastes nudus, and the remaining specimens as Sebastes pachycephalus. Sebastes nudus is characterized by the absence of scales below the base of the dorsal fin spines; the absence of dark spots on the dorsal, anal, and caudal fins; and the presence of distinct yellow or brownish-red markings on the dorsum (when fresh). The most similar species S. pachycephalus differs from S. nudus in having minute scales below the base of the dorsal fin spines. We propose the new Korean name "Hwang-jeom-gae-bol-rak" for S. nudus, and redescribe S. pachycephalus.
