Title: New species of the Gorgonian genus Plumigorgia (Coelenterata: Octocorallia) with a review of the family Ifalukellidae
Abstract: Three new species of the gorgonian genus Plumigorgia Nutting, 1910, are described and illustrated by scanning electron micrography. P. terminosclera sp. nov., P. schuboti sp .nov., and P. astroplethes sp.nov. were all collected on the Australian Great Barrier Reef. The family Ifalukellidae is summarised and a taxonomic key is given. All other known species of the family are also illustrated.
