A single specimen (273.1 mm in standard length) of the monacanthid Thamnaconus tessellatus was caught by one-boat trawl from western Jeju Island and then collected at Busan Cooperative Fish Market (BCFM) on 30 May 2015. The specimen is characterized by both head and body with many dark brown spots densely, posterior margin of caudal fin no black, first dorsal spine originates the posterior half of eye, and 34~37 dorsal fin rays. This is the first record of T. tessellatus in Korea; we therefore add the species to the Korean fish fauna. According to the Yamada et al. (1995), we propose the Korean name, "Nam-byeol-jwi-chi" for this species.
