60 Ophiurid species, mainly bathyal, were sampled by MUSORSTOM Expedition in the area of Manila
(Philippine Islands) 4 species are new for Science: Astrotoma drachi, Ophioplinthaca manillae, Ophiurothamnus
musorstomae, Ophiotreta speciosa. 13 species are refound for the first time since their original diagnosis. A new
combination is established, Ophiodaphne formata, because Ophiodaphne materna Koehler (1930) appears to be the
juvenile form of “Amphioplus” formatus (Koehler, 1905). Two other species are synonymized: Ophiomoeris pentagona
Murakami (1944) with Ophiogyptis nodosa Koehler (1905) and Ophiothrix cumulata Koehler (1922) with
Ophiothrix crassispina Koehler (1905). Amphiacantha transacta Koehler (1930) is transferred into fhe genus
Amphilimna Verrill.

Abstract [+]

During the CALSUB cruise, bathyal environments were explored off the New Caledonia corallian platfdrms (southwestern Pacific). Green algae were observed down to a depth of 1 IO m, and red algae down to 145 m. Algal blocks, pebbles and sands contribute to sedimentation to a depth of 400 m and beyond, and are mixed with autochthonous fossils and bioclasts produced by bathyal benthos. Epibathyal fauna suggests similarities with Jurassic and Cretaceous fauna of Tethyan margins (Nautilus, pleurotomarian gastropods, sponges, brachiopods and crinoids…). Richness and abundance of the benthos are the highest in areas where currents are frequent between 300 m and 700 m (sometimes 10 to 20 terebratulid brachiopods per m2 or dense populations of echinoderms entirely covering the substrate). Such currents induce erosion of' substrate or bioclastic accumulations. Biocorrosion seems to be very active in erosion processes, especially on hard grounds. Burrows and traces show the importance of sediment bioturbation on slopes. The occurrence on bathyal slope of some taphonomic processes previously known from geological series and generally considered as closely related lo shallow-water environments should be emphasized.

Abstract [+]
[-]
L'exploration de la faune profonde de NouvelleCalédonie a débuté par des campagnes d'essai de 1977 à 1979 sur des fonds de 200 m à 1000 m au large de la Grande Terre, de l'île des Pins et des îles Loyauté (Intès, 1978). A partir de 1985, elle s'est élargie et intensifiée avec les campagnes MUSORSTOM 4 à 6 et CHALCAL (Richer de Forges, 1990), BIOCAL, BIOGEOCAL et SMIB, complétées par des observations directes à l'aide de la soucoupe plongeante Cyana lors de la campagne CALSUB. Nous ne donnerons ici que les grands traits de l'étagement de la macrofaune et de la mégafaune benthique en insistant sur les observations directes insitu lors de la campagne CALSUB et sur la liaison avec les caractères du milieu.
