Identified to family based on general morphology (Fig. 9). Genetic data for this taxon with new GenBank accession numbers are provided in Table 2. Diagnosis The specimen superficially resembles Bathygorgia profunda Wright (1885) first described in the Narrative (Part 2) of the HMS Challenger voyage and more fully described in Wright and Studer (1889) where a type locality from station 241 between Yokohama and Hawaii (depth 4206m) is indicated. Morphologically-similar specimens based on AUV or ROV image data is also referred to this species in the CCZ megafauna atlas ( International Seabed Authority 2016 ). However, this specimen is distinguished by the presence of large needle sclerites (Fig. 9) that extend between the bases of the tentacles (which are not present in Bathygorgia ), and the body sclerites being predominantly small needles rather than the disorganised rods that typify Bathygorgia . The present specimen belongs to a new genus and species (Watling et al. in prep). For a recent discussion on Keratoisid corals, see Duenas et al. (2014) , Lapointe and Watling (2015) and Moore et al. 2016 . No genetic matches at Genbank but forms a cluster with Keratoisis and Orstomisis sequences published (Fig. 5).
