    Through a taxonomic study of solitary corals collected from the subtidal zone of the Navarone Cliffs in Chujadolocated in the northern part of Jeju Island, Korea-at a depth of 10 to 15 meters in 2021, a new species, Paracyathus aurantius n. sp., has been described and added to the anthozoan fauna. As a result of this study, a total of 27 species within the genus Paracyathus have now been reported. This new species is characterized by its bright orange color, cylindrical and robust corallum shape, five cycles of septa, a septal formula of S1=S2>S3>S4>S5, up to 3rd pali, and a columella composed of approximately 30 papillae.
