Twenty-two species are illustrated and described in detail from material in the marine invertebrate collection of the South African Museum, Cape Town. Most of this material has been collected recently by means of SCUBA and dredge. Eight additional species are mentioned from literature sources but, since satisfactory material is not available for examination, these are not illustrated or described in detail. Nine genera are represented that do not occur in lt 200 m depth; these are included in the text and key but most are not identified to species. There are at least seven genera in which species identification is uncertain or not possible at present. Several species are considered problematical. These belong mainly to the families Melithaeidae and Ellisellidae, which are in need of thorough revision before most material can be properly assigned even to genus. Two gorgonian genera are here considered southern African endemics: Homophyton and Ideogorgia. Scanning electron micrographs of sclerite form complement all detailed species descriptions. New information has allowed for the revision of taxonomic status and extent of intraspecific variation of several species. A key is provided to all identified species and genera that are considered valid and known to occur in southern Africa. This regional account of the gorgonian fauna includes ten families, 30 genera, and 24 identified species that are here considered valid. This includes six new combinations and 17 genera recorded from southern Africa for the first time. At least two species are known that are presently unidentified but probably represent undescribed species; these are not included in the present account.10aBiogeography (Population Studies)10aEcology (Environmental Sciences)10aGeneral Life Studies10aMarine Ecology (Ecology) (Environmental Sciences)10aPhysiology10aSystematics and Taxonomy1 aWilliams, Gary, C.  uhttp://library.louisiana.edu/cgi-bin/proxy?http://search.ebscohost.com/login.aspx?direct=true&db=bxh&AN=BACD199395005496&site=ehost-live01421nas a2200253   4500008004100000245014500041210006900186300001200255490000800267520052300275653001300798653003800811653002400849653001900873653001500892653001400907653001500921653001500936653001500951653002900966653001300995100001801008856014101026       1990                        eng d00aA new isidid octocoral (Anthozoa: Gorgonacea) from New Caledonia, with descriptions of other new species from elsewhere in the Pacific Ocean0 anew isidid octocoral Anthozoa Gorgonacea from New Caledonia with  a205-2280 v1033 aThe status of the genera Isidella, Acanella, and Lepidisis in the subfamily Keratoisidinae is discussed and the new species Isidella trichotoma and Acanella dispar are described and illustrated.
