title: Overview of the genus Briareum (Cnidaria, Octocorallia, Briareidae) in the Indo-Pacific, with the description of a new species.
abstract: The status of Indo-Pacific Briareum species (Cnidaria, Octocorallia, Briareidae) is reviewed by presenting their sclerite features and habitus descriptions. Following the re-examination of type material, museum specimens and newly collected specimens, a species identification key is provided. The species distributions are discussed and updated distribution ranges are depicted. Moreover, a new taxon, Briareum cylindrum sp. n. is described and depicted, whereas Briareum excavatum (Nutting, 1911) is synonymised with Briareum stechei (Kükenthal, 1908). Briareum hamrum (Gohar, 1948) is recorded from the Persian Gulf and Oman Sea for the first time. Consequently, in total four Briareum species are recognized in the Indo-Pacific; Briareum hamrum from the western Indian Ocean, and Briareum cylindrum sp. n., Briareum stechei, and Briareum violaceum from the central and eastern Indo-Pacific region.
