The genus Lanocira Hansen, 1890 is recorded from the southwestern Pacific for the first time. Lanocira grebarree sp. nov. from the Great Barrier Reef is described, and Lanocira gardineri Stebbing, 1904 and Lanocira sp. cf. anasicula Jones, 1982 are recorded from the Great Barrier Reef and Hibernia Reef, in the Timor Sea off Western Australia, respectively. Lanocira grebarree sp. nov. can be identified by the anteriorly rounded, upturned and short rostral process in males in combination with the lack of stiff setae on the dorsal surface of the pleotelson. The similar L. gardineri Stebbing, 1904 is distinguished from L. grebarree sp. nov. by the presence of stiff hyaline setae on the dorsal surface of the pleotelson. A key is provided to the Australian species of Lanocira.

Abstract. This research demonstrates the use of an unmanned aerial vehicle (UAV) to characterize the gaseous (CO2) and particle (10–500 nm) emissions of a ship at sea. The field study was part of the research voyage The Great Barrier Reef as a significant source of climatically relevant aerosol particles on-board the RV Investigator around the Australian Great Barrier Reef. Measurements of the RV Investigator exhaust plume were carried out while the ship was operating at sea, at a steady engine load of 30 %. The UAV system was flown autonomously using several different programmed paths. These incorporated different altitudes and distances behind the ship in order to investigate the optimal position to capture the ship plume. Five flights were performed, providing a total of 27 horizontal transects perpendicular to the ship exhaust plume. Results show that the most appropriate altitude and distance to effectively capture the plume was 25 m above sea level and 20 m downwind. Particle number (PN) emission factors (EF) were calculated in terms of number of particles emitted (#) per weight of fuel consumed (Kg fuel). Fuel consumption was calculated using the simultaneous measurements of plume CO2 concentration. Calculated EFPN were between 9.19 × 1014 and 5.15 × 1015 #∙(Kg fuel)−1. These values are in line with those reported in the literature for ship emissions ranging from 0.2 6.2 × 1016 #∙(Kg fuel)−1 to 6.2 × 1016 #∙(Kg fuel)−1. This UAV system successfully assessed ship emissions to derive emission factors (EFs) under real world conditions. This is significant as, for the first time, it provides a reliable, inexpensive and accessible way to assess and potentially regulate ship emissions.

Predation Rates

Quantitative evidence on predation rates on soft corals is presented for the first time. These measured predation rates were low. Less than 1% of the soft coral colonies present in mapped areas at Heron Island and Beaver Reefs had bite marks. Evidence suggests that over 51% of these bite marks were more than two months old. Predators included the mollusc Ovula ovum and two species of chaetodontid fishes that have not been recorded before as feeding on soft corals.

A New Species

Eight species of Philocheras (Crustacea: Caridea: Crangonidae) are reported from the Northwest Shelf of Western Australia. One species is new to science Philocheras anthonyi sp. nov. Five species are reported for the first time from Australian waters, P. angustirostris (De Man, 1918), P. incisus (Kemp, 1916), P. japonicus (Doflein, 1902), P. modestus (De Man, 1918) and P. plebs (Kemp, 1916). A range extension within Australia is reported for Philocheras lowisi (Kemp, 1916) and P. planoculminus Bruce, 1994. These records expand the number of Philocheras species previously recorded from Australian waters from ten to 16. A revised key and illustrated guide to the species from Australia is provided.

SUMMARYIsolation can provide marine ecosystems with a refuge from human impacts. However, information on the biodiversity, ecology and fisheries of remote regions is often sparse. The proposed Coral Sea Marine Reserve could create one of the world's largest and most remote marine parks, yet little information is available to inform discussions. Fish captures from the Coral Sea and adjacent Great Barrier Reef (GBR) were assessed from reports contained in a chronology of spearfishing publications from 1953 to 2009, and reveal for the first time the history of recreational spearfishing in the Coral Sea. Although the area is perceived as relatively untouched, the data indicate that spearfishers have frequented Coral Sea reefs for at least 43 years and reported captures have increased exponentially. Post-1993 trophy captures in the Coral Sea (mean 23 kg) were larger than the adjacent GBR (9 kg). Reef species characterize the GBR catch, while large pelagic species characterize the Coral Sea catch. Provided that functionally important fishes are not targeted, the relatively small scale of recreational spearfishing and the focus on pelagic species suggests that spearfishing currently exerts limited pressure on the ecology of Coral Sea reefs.

The genera Tenupedunculus Schultz, 1982 and Stenobermuda Schultz, 1979 are recorded for the first time from beyond the Southern Ocean, at the Great Barrier Reef, Australia. Tenupedunculusserrulatussp. n. and Stenobermudawaroogasp. n. are described from Heron Island and Lizard Island respectively, both in the Great Barrier Reef. The genus Tenupedunculus is revised and a new diagnosis presented, with Tenupedunculusvirginale Schultz, 1982, T.pulchrum (Schultz, 1982), and T.serrulatussp. n. being retained within the genus, and the remaining species here regarded as Stenetriidaeincertae sedis (eight species).

We recognize seven species in this group, five of which are described here. Priolepis profunda (Weber) occurs in central Indonesia and western Australia; P. anthioides (Smith) is known only from Zanzibar; P. aithiops n.sp. and P. sticta n.sp. are known only from Flores, Indonesia; P. fallacincta n.sp. occurs fairly widely in the western Pacific from Taiwan to Fiji and the Great Barrier Reef; P. randalli n.sp. is present in the Persian Gulf (and probably the Red Sea); and Priolepis RW sp. 8, to be described by other workers, is known from Japan through to western Australia, the Great Barrier Reef, and New Caledonia. The monotypic Egglestonichthys (known from a single specimen from the South China Sea) exhibits all the defining characteristics of Priolepis, and represents the plesiomorphic sister-group of either Priolepis, if the latter proves to be monophyletic, or of a monophyletic group composed of Priolepis, Trimma, Trimmatom, Paratrimma, and possibly some other genera. The entire clade is defined by two autapomorphies: loss of the cephalic sensory canals and associated pores, and a broad gill opening extending anteroventrally to below at least the vertical limb of the preopercle.

A systematic study has been made of the species of Ixodes (Ixodidae) occurring in Australia. Nineteen species were recognized in the material available for examination, namely I. uriae, I. kohlsi, I. eudyptidis, I. pterodromae, I. simplex simplex, I. vespertilionis, I. ornithorhynchi, I. tasmani, I. hydromyidis, I. australiensis, I. victoriensis, I. fecialis, I. antechini, I. vestitus, I. holocyclus, I. confusus, I. cornuatus, I. hirsti, and I. trichosuri. Four of these, I. antechini, I. cornuatus, I, confusus, and I. trichosuri, are regarded as new species and I. simplex simplex and I. pterodromae are recorded from Australia for the first time. I. rothschildi recorded by Arthur (1953) from Western Australia was not encountered. A detailed description with appropriate figures is given for each species, including all known stages in the life cycle, together with data on host range and geographical distribution. Keys are supplied for the known males, females, nymphs, and larvae and a classified host list has been compiled.
