Nine new lichomolgid copepods, including two new genera, Ecphysarion and Unicispina, are described, all associated with various species of the scleractinian genus Acropora in New Caledonia, at Ceram and Obi in the Moluccas, and at Enewetak Atoll in the Marshall Islands: Schedomolgus idanus, S. majusculus, S. insignellus, S. exiliculus, Scyphuliger eumorphus, S. aristoides, Ecphysarion ampullulum, E. spinulatum, and Unicispina latigenitalis. New records are given for Ecphysarion lobophomm (Humes & Ho, 1968), comb. nov., Scyphuliger concavipes Humes, 1991, S. manifestus Humes, 1991, and S. tenuatus (Humes, 1990).

A new species of tube-dwelling diatom, unusual in being araphid, is described from benthic coral reef habitats in Guam, Palau, Puerto Rico and Jamaica. Gato gen. nov. is heteropolar and heterovalvar, exhibits very fine striae delimiting a narrow and irregular sternum, and possesses a series of rimmed pores on each side of the foot pole. One valve of the frustule has a rimoportula at the foot pole, but both valves possess a rimoportula at the head pole. The generitype, G. hyalinus sp. nov. forms small, branched colonies. Individual cells are oval, slightly tapered along the apical axis, 30–40 µm x 13–15 µm, with 60–70 striae in 10 µm. On the foot pole with a rimoportula the rimmed pores are connected to the sternum by diagonal striae; several additional rimmed pores interrupt transapical striae further up both valves. We compare valve structure of G. hyalinus with Florella portoricensis and F. pascuensis, which we report for the first time from the Marshall Islands, and to Licmophora spp. We find no taxa to which this genus is related, and can identify no structure potentially homologous to the series of rimmed pores among the diatoms.

AbstractRecurring outbreaks of crown-of-thorns starfish (COTS) severely damage healthy corals in the Western Pacific Ocean. To determine the source of outbreaking COTS larvae and their dispersal routes across the Western Pacific, complete mitochondrial genomes were sequenced from 243 individuals collected in 11 reef regions. Our results indicate that Pacific COTS comprise two major clades, an East-Central Pacific clade (ECP-C) and a Pan-Pacific clade (PP-C). The ECP-C consists of COTS from French Polynesia (FP), Fiji, Vanuatu and the Great Barrier Reef (GBR), and does not appear prone to outbreaks. In contrast, the PP-C, which repeatedly spawns outbreaks, is a large clade comprising COTS from FP, Fiji, Vanuatu, GBR, Papua New Guinea, Vietnam, the Philippines, Japan, Micronesia, and the Marshall Islands. Given the nature of Pacific Ocean currents, the vast area encompassing FP, Fiji, Vanuatu, and the GBR likely supplies larvae for repeated outbreaks, exacerbated by anthropogenic environmental changes, such as eutrophication.
