The genus Calcigorgia was established by Broch (1935) and it was known from only a single small specimen of C. spiculifera collected from a depth of 150–165 m in the Sea of Okhotsk by the Russian vessel “Ara”. Leptogorgia beringi Nutting 1912, was transferred to the genus Stenogorgia by Kükenthal (1919). Later on the genus Stenogorgia was synonymized with Swiftia by Deichmann (1936). Finally, the species was transferred to the genus Calcigorgia by Bayer (USNM) in his unpublished manuscript we have at our disposal. Because of this manuscript, the database of the USNM (http://collections.nmnh.si.edu/search/iz/) mostly referred to specimens of this species as Calcigorgia beringi. Calcigorgia has been a Subarctic North Pacific gorgonian genus until Dautova (2007) described C. japonica from a fragment from the Sea of Japan and extended the distribution of this genus to the south. Dautova (2007, 2018) compared her new species with Calcigorgia beringi (Nutting, 1912) and C. spiculifera Broch, 1935 in her publication. The genus was never revised. In order to identify recently collected Calcigorgia specimens from Japan we re-examined material of the five known species of that genus, Calcigorgia beringi (Nutting, 1912), C. spiculifera Broch, 1935, C. japonica Dautova, 2007, C. matua Dautova, 2018, and C. simushiri Dautova, 2018. Dr. Stephen Cairns (USNM) provided us with SEM images of USNM 30044, the holotype of C. beringi and informed us about an unpublished manuscript of the late Dr. F.M. Bayer (USNM: National Museum of Natural History, Smithsonian Institution, Washington D.C., USA) in which he proposed a redescription of Calcigorgia spiculifera and C. beringi, and a new species, C. gracilis. On our request Dr. Cairns was so kind to also send us the SEM images of the material used by Bayer for C. spiculifera and “C. gracilis”, and his unpublished manuscript. ZIN (Museum of the Zoological Institute of the Russian Academy of Sciences St.Petersburg, Russia) Calcigorgia material provided us with specimens of C. japonica and C. matua. As one of the specimens of the recently collected material proved to be Bayers’s “C. gracilis”, we refrain from giving a new name for this new species. A second species, C. pacifica sp. n., proved to be the most common Calcigorgia species in Japanese waters. A third new species was discovered by the first author during a re-examination of the collection of the USNM, C. gigantea sp. n. Finally, we synonymize C. simushiri Dautova, 2018 with C. spiculifera Broch, 1935. Assignment of Calcigorgia to the Acanthogorgiidae was considered questionable by Dr. Bayer in his unpublished manuscript but was never challenged (see discusion).
