Caridina longirostris H. Milne Edwards, 1837 described from specimens supposedly from La Macta River near Oran, Algeria, is an emblematic species of the ‘C. nilotica complex’. Until now this species was thought to have a wide distribution in the Indo-Pacific region. Recently, numerous specimens identified as C. longirostris were collected from various Indo-West Pacific localities. In the context of integrative taxonomy, both old and newly collected specimens were morphologically and genetically studied. Four species allied to C. longirostris are here identified: C. appendiculata Jalihal & Shenoy, 1998, C. brevidactyla Roux, 1920, C. gracilipes De Man, 1892 and C. meridionalis Roux, 1926. Detailed re-descriptions of these four species are given as well as their geographical and ecological distributions. Caridina nilotica var. brevidactyla is revalidated as the species C. brevidactyla, and C. coulaborensis Richard & Clark, 2014, C. fritzi Richard & Clark, 2014 and C. solamulieres Richard & Clark, 2014 are considered junior synonyms of C. meridionalis. The position of these species in the troublesome ‘C. nilotica complex’ is clarified and some species are synonymised. A key is provided to facilitate identification.

The present study focuses on shrimps belonging to the genus Lysmata Risso, 1816, collected from Madagascar during the Atimo Vatae expedition carried out in 2010. Lysmata malagasy sp. nov. is a new species belonging to the clade named “long accessory ramous” or “cosmopolitan” in previous phylogenetic studies. The new species can be distinguished from the only two other representatives of this group in the Indo-west Pacific, L. ternatensis De Man, 1902, and L. trisetacea (Heller, 1861), by the accessory ramus of the lateral antennular flagellum consisting of four elongated articles. Lysmata lipkei Okuno & Fiedler, 2010 is reported here from Madagascar with a remarkable extension of its known range after its original description from Japan. This species has also been reported from Singapore and, as alien species, from Brazil. Lastly, L. kuekenthali De Man, 1902 known from numerous localities in the Indo-West Pacific biogeographic area, is reported for the first time from Madagascar. Results of the present morphological and molecular analyses suggest that L. hochi Baeza & Anker, 2008 from the Caribbean Sea is a synonym of the Indo-West Pacific L. kuekenthali, and thus the latter species is alien in the western Atlantic.

With six valid species, Luciobrotula is a small genus of the family Ophidiidae, commonly known as cusk-eels. They are benthopelagic fishes occurring at depths ranging from 115–2300 m in the Atlantic, Indian, and Pacific Oceans. Among them, Luciobrotula bartschi is the only known species in the West Pacific. Three specimens of Luciobrotula were collected from the Philippine Sea, Bismarck Sea, and Solomon Sea in the West Pacific during the AURORA, PAPUA NIUGINI, and MADEEP expeditions under the Tropical Deep-Sea Benthos program, and all of them were initially identified as L. bartschi. Subsequent examination with integrative taxonomy indicates that they belong to two distinct species, with the specimen collected from the Solomon Sea representing a new species, which is described here. In terms of morphology, Luciobrotula polylepis sp. nov. differs from its congeners by having a relatively longer lateral line (end of the lateral line below the 33rd dorsal-fin ray) and fewer vertebrae (abdominal vertebrae 13, total vertebrae 50). In the inferred COI gene tree, the two western Pacific species of Luciobrotula do not form a monophyletic group. The genetic K2P distance between the two species is 13.8% on average at the COI locus.

The species of the cosmopolitan sponge genus Mycale occurring in the tropical Indo-West Pacific region and adjacent subtropical waters are reviewed taxonomically. Specimens incorporated in the collections of the Naturalis Biodiversity Center form the basis of this comprehensive study, supplemented by (type) specimens borrowed from or examined in other institutions. Specimens available numbered 351, belonging to 44 species, including 14 species new to science, Mycale (Aegogropila) prognatha sp.nov., Mycale (Carmia) amiri sp.nov., Mycale (Carmia) fungiaphila sp.nov., Mycale (Carmia) monomicrosclera sp.nov., Mycale (Carmia) tenuichela sp.nov., Mycale (Carmia) tubiporicola sp.nov., Mycale (Carmia) tydemani sp.nov., Mycale (Mycale) asigmata sp.nov., Mycale (Mycale) grandoides sp.nov., Mycale (Mycale) sundaminorensis sp.nov., Mycale (Naviculina) mascarenensis sp.nov., Mycale (Paresperella) sceptroides sp.nov., Mycale (Paresperella) seychellensis sp.nov., Mycale (Zygomycale) sibogae sp.nov. Three species, indicated by the designation ‘aff.’, were not definitely assigned to known or new species due to uncertainty of their identity. The genus Kerasemna, previously considered a junior synonym of Mycale, was revived as an additional subgenus Mycale (Kerasemna). One species, previously assigned to the genus Desmacella as D. lampra De Laubenfels is here reassigned to Mycale, subgenus at present undecided. Additionally, species previously reported from the region but not represented in our collections are briefly characterized and discussed. We propose new names Mycale (Mycale) mauricei nom.nov. for Mycale macrochela Burton (junior primary homonym of Mycale fistulata var. macrochela Hentschel) and Mycale (Mycale) bouryesnaultae nom.nov. for Mycale (Mycale) fibrosa Boury-Esnault & Van Beveren (junior primary homonym of Mycale (Aegogropila) adhaerens subsp. fibrosa Koltun). Keys to the species of each subgenus occurring in the region are provided. The opportunity of having studied this comprehensive set of species and specimens from the tropical Indo-West Pacific is taken to review and discuss the morphological and biogeographical data gathered so far on the genus Mycale. The genus currently comprises approximately 255 accepted species, with highest diversity focused in tropical Atlantic and Indo-West Pacific regions as well as in warm-temperate Mediterranean-Atlantic regions.

The taxonomy of two Indo-West Pacific species of pilumnid crabs, Pilumnus scabriusculus Adams & White, 1849, and P. sluiteri De Man, 1892, is clarified. Pilumnus sluiteri has long being synonymised under P. scabriusculus but re-examination of the types and other material shows that there are distinct differences between them, notably in the form of the carapace, mouthparts, chelipeds and male first pleopods. They are here regarded as two distinct species.

Abstract A new species of the cyclopoid copepod genus Paramacrochiron, P. tridentatum, which is parasitic on the rhizostome medusa, Versuriga anadyoneme (Maas, 1903), is described from Vietnam. This is the tenth species within the genus. The new species is distinguishable from other congeners by the combination of the following features: (1) female second maxillipedal segment with 3 acutely pointed processes terminally; (2) female leg 4 endopod as long as or slightly longer than exopod; (3) male maxilliped with a small, acutely pointed process at subterminal corner of the first segment and a row of relatively coarse spinules along the inner margin of the second segment. The present study most probably implies a high species diversity of Paramacrochiron in the tropical and subtropical waters of the Indo-West Pacific region.

Kava has been introduced into Aboriginal communities in Northern Australia. Persons from Yirrkala in North East Arnhem Land visiting the South Pacific region on study tours have been impressed by their welcome in Kava bowl ceremonies, and some of them hoped that the Aborigines might use Kava instead of alcohol.In 1983 many Aboriginal people in Arnhem Land used Kava, and much more was used in 1984. By 1985 it became a social epidemic or ‘craze’ in many communities. Rings of people of both sexes and of all ages often sit together under trees around Kava bowls for many hours. They may drink up to a hundred times the amount normally drunk in the Pacific Islands by the same number of people in the same time.

This article draws upon the Pacific Media Assistance Scheme (PACMAS) State of Media and Communication Report to examine the implications of a changing media landscape for journalism practice in the Pacific region. The report contributes to an understanding of the diverse media and communications environments in the Pacific Islands (PI) region and captures aspects of the variations both in media, and in context, across and within the 14 Pacific Islands countries. This article highlights the need for synergies in the Pacific Islands to strengthen legislation, capacity-building initiatives and content production in a fast-changing digital environment.
