| The current centuries old classification of the family Nephtheidae is still mostly based on colony morphology. In this family the Indo-Pacifc genera Litophyton, Nephthea, Dendronephthya and Stereonephthya, and the Atlantic genus Neospongodes form a complex mix of closely related, poorly described species which cannot be recognized using only colony morphology. Attempts with the more modern approach of comparing skeleton composition (sclerites) have been only partly successful because of the extreme variation of sclerite forms present in these genera. The genus Chromonephthea Van Ofwegen, 2005, introduced for several species previously assigned to Dendronephthya, Nephthea and Stereonephthya, was established with sclerite morphology, but the true generic... |

| Bioscreening guided fractionation of the extracts of soft corals Lobophytum crassum and L. rotundum using brine shrimp larvae cytotoxicity assay led to the isolation of a cembranolide diterpene (E,E,E)-6,10,14-trimethyl-3-methylene- 3a,4,7,8,11,12,15,15aoctahydrocylotetradeca [b]furan-2(3H)-one (1). This diterpene, identified as cembranolide compound 1, was found to be active against the multidrug-resistant and chloroquine-sensitive strains of Plasmodium falciparum malaria parasite in vitro. It also possessed cytotoxic properties. |

| Corals are associated with dinitrogen (N-2)-fixing bacteria that potentially represent an additional nitrogen (N) source for the coral holobiont in oligotrophic reef environments. Nevertheless, the few studies investigating the assimilation of diazotrophically derived nitrogen (DDN) by tropical corals are limited to a single scleractinian species (i.e., Stylophora pistillata). The present study quantified DDN assimilation rates in four scleractinian and three soft coral species from the shallow waters of the oligotrophic Northern Red Sea using the N-15(2) tracer technique. All scleractinian species significantly stimulated N, fixation in the coral-surrounding seawater (and mucus) and assimilated DDN into their tissue. Interestingly, N-2 fixation was not... |

| Four new genera, Rhytisma, Klyxum and Skamnarium (family Alcyoniidae) and Sansibia (family Xeniidae), are proposed to accommodate a number of species wrongly assigned to some established genera. A large number of the species concerned have been previously included in the genus Alcyonium, and remarks are made concerning the heterogenous nature of that genus. The reassignment of Parerythropodium hicksoni Utinomi, 1972, to Erythropodium, Alcyonium gracillimum Kükenthal, 1906, to Scleronephthya, and Clavularia hamra to Briareum is also discussed, and the existence of Funginus Tixier-Durivault, 1987, as a replacement name for Fungulus Tixier-Durivault, 1970, is highlighted. |

| A synopsis of the 97 species of lichomolgid copepods known to be associated with tropical IndoPacific shallow-water alcyonaceans is given (Madagascar, New Caledonia, Moluccas, Philippines, and Enewetak Atoll). One new genus and 29 new species are included, distributed among the lichomolgid genera Acanthomolgus (2 new species), Alcyonomolgus (1), Colobomolgus (2), Critomolgus (3), Doridicola (5), Paradoridicola (7), Paramolgus (8), and Telestacicola (1). The alcyonacean hosts, numbering more than 100 species, include members of the genera Alcyonium, Anthelia, Capnella, Cespitularia, Cladiella, Dendronephthya, Heteroxenia, Lemnalia, Litophyton, Lobophytum, Nephthea, Paralemnalia, Parerythropodium, Sarcophyton, Sinularia, Siphonogorgia, Stereonephthya,... |
