Colour in preservative. Carapace reddish brown with orange granules on the lobes. Ambulatory legs brown with beige setae. Chelipeds reddish brown with orange granules on the lobes dorsally, and beige ventrally, fingers black. Abdomen brown with beige setae. Remarks. Acteodes mutatus occurs across tropical Australia and the Indo-West Pacific. It is similar to Acteodes semoni (Ortmann, 1894) but can be distinguished by the basal antennal segment which fills the orbital hiatus that is normally open, whereas in A. semoni the basal antennal segment is excluded from the orbit. Another character used to define A. mutatus is the subdivision of 3M into three parts. In our specimen this subdivision is not well defined. However, it is likely this character is variable within the species. Distribution. Indo-west Pacific (Mergui Archipelago, to southern Japan, and east to French Polynesia) (Davie, 2002).Published as part of Iwasa-Arai, Tammy, McCallum, Anna W. & Taylor, Joanne, 2015, Oceanic Shoals Commonwealth Marine Reserve survey reveals new records of xanthid crabs (Crustacea: Brachyura: Xanthidae) from northern Australia, pp. 1-11 in Memoirs of Museum Victoria 73 on page 2, DOI: 10.24199/j.mmv.2015.73.01, http://zenodo.org/record/806511

Liomera edwardsi was the only species with more than one specimen collected during the Timor Sea Oceanic Shoals survey. Liomera edwardsi is very similar to L. tristis (Dana, 1852), L. laevis (A. Milne-Edwards, 1873), L. sagamiensis (Sakai, 1939) and L. nigropunctata (Serène & Van Luom, 1960), but can be distinguished by a projecting areole well separated from 2M and 1F (Serène, 1984) on the dorsal surface. This species was previously recorded in Australia by Odhner (1925) from one specimen collected from Holothuria Bank, Northwest Australia. Distribution.

Abdomen white (Fig. 5). Colour in preservative. Carapace pale orange with white anterolateral margins, 1P, 2P and 3R white. Ambulatory legs light orange. Chelipeds orange dorsally and white ventrally with dark brown fingers. Abdomen white. Remarks. Within the genus Liomera, this species is characterised by a completely divided 2M region, which makes it similar to, Liomera monticulosa (A. Milne-Edwards, 1873), Liomera rugipes (Heller, 1861), and Liomera rubra (A. Milne-Edwards, 1865). It differs from the latter three species, which have 1M separated from the interior part of 2M. Serene (1984) describes L. margaritata with well-defined regions 4L, 5L, and 6L, but in our specimens these regions are fused and not well defined. Also, colour in live specimens are different, described as uniformly pale violet by Serene (1984), while our specimens are orange colour with white anterolateral margins. As the G1 morphology agrees well with illustrations of L. margaritata provided by Serene (1984), we conclude that the variation described above is likely to be intra-specific. Distribution. Queensland (Great Barrier Reef, NE coast); Indo-west central Pacific Oceans (Madagascar and Red Sea to Japan, New Guinea, Samoa, New Caledonia). Depth range subtidal– 107 m.Published as part of Iwasa-Arai, Tammy, McCallum, Anna W. & Taylor, Joanne, 2015, Oceanic Shoals Commonwealth Marine Reserve survey reveals new records of xanthid crabs (Crustacea: Brachyura: Xanthidae) from northern Australia, pp. 1-11 in Memoirs of Museum Victoria 73 on page 5, DOI: 10.24199/j.mmv.2015.73.01, http://zenodo.org/record/806511

Hosts Globicephala macrorhynchus, Peponocephala electra (new host record), Stenella clymene (new host record). Diagnosis (adapted from Haney et al. 2004) Anterior margin of pereonite 2 bilobed, with intern lobe much larger in size (Figure 8 (a)); lateral gills uniramous and ventrally directed, not reaching anterior margin of pereonite 2 (Figure 8 (b,c)); accessory gills of male subtriangular, approximately two-thirds length of lateral gill; pereonites 3 and 4 lacking acute ventral processes; pereonites 5 and 6 of male bearing two pairs of acute ventral processes, pereonite 7 of male with one pair of acute ventral processes (Figure 8 (d)). Remarks Syncyamus is a genus of small cyamids composed of four described species all of which are ectoparasites of warm-water dolphins. Syncyamus ilheusensis differs from S. aequus Lincoln and Hurley, 1981 by the number of acute ventral processes on pereonite 5, the presence of accessory gills in males and larger body size. Syncyamus ilheusensis differs from S. pseudorcae Bowman, 1955 by the asymmetrical lobes on anterior margin of pereonite 2, the absence of acute ventral processes on pereonites 3 and 4, and the presence of an acute process on the postero-medial margin of the basi-ischium of pereopod 7. The original description of S. ilheusensis was based on specimens collected from a short-finned pilot whale (G. macrorhynchus) stranded on the north-east coast of Brazil (Haney et al. 2004). The specimens examined from P. electra and S. clymene agree with the general description of S. ilheusensis. A small difference was noticed, in the presence of a large blunt process on the postero-medial margin of the basi-ischium of pereopod 7 instead of a small acute process (Figure 8 (d)). Comparative material examined from G. macrorhynchus also exhibited a blunt process. This is a new record of S. ilheusensis for Ceará, which was also found on different host species, P. electra and S. clymene. It is known that melon-headed whales host another species of whale-louse, Isocyamus delphinii (Wardle et al. 2000); however, the two cyamids were not recorded together. Cyamids from Stenella clymene were previously assessed by Carvalho et al. (2010), who reported the whale louse S. pseudorcae.Published as part of Iwasa-Arai, Tammy, Carvalho, Vitor Luz & Serejo, Cristiana Silveira, 2017, Updates on Cyamidae (Crustacea: Amphipoda): redescriptions of Cyamus monodontis Lütken, 1870 and Cyamus nodosus Lütken, 1861, a new species of Isocyamus, and new host records for Syncyamus ilheusensis Haney, De Almeida and Reis, 2004, pp. 2225-2245 in Journal of Natural History (J.

Both species have chelipeds with chisel-shaped fingers, and a single large subproximal tooth on the pollex. According to Serène (1984) the two species can be distinguished by the amount of granulation on the carapace. <i>Atergatopsis tweediei</i> is entirely smooth on most of its median carapace, with granules only on the anterolateral margins. While the carapace of <i>A. granulata</i> is entirely covered in granules, they are smaller and less numerous in the median and posterior parts. In our specimen, region 3M of the carapace is almost smooth but all other regions are granular.</p> <p> <i>Distribution.</i> Madagascar, Zanzibar, Pakistan (Karachi), Aldabra, South China Sea and New Guinea (Sèrene, 1984).
