On the crangonidae (Crustacea : Decapoda : Caridea) of the Philippines from the PANGLAO 2004 and PANGLAO 2005 expeditions

Eleven species of the caridean family Crangonidae are reported from the material collected by the Philippine PANGLAO 2004 and PANGLAO 2005 expeditions. Although they have been reported from the Philippines before, all the species have their colouration described and illustrated here for the first time.

Report on some species of Palaemonidae (Crustacea, Decapoda) from French Polynesia

Based on material collected from French Polynesia and deposited in the Museum national d'Histoire naturelle, Paris, the present paper reports 31 palaemonid shrimp species, which belong to the Palaemoninae (two genera, three species) and to the Pontoniinae (12 genera, 28 species), including six new species. The new species are: Izucaris crosnieri n. sp., Periclimenes alexanderi n. sp., P. josephi n. sp., P platydactylus n. sp., P polynesiensis n. sp. and P vicinus n. sp. Detailed descriptions and illustrations of the new species are provided. Besides the six new species, ten other species are recorded for the first time from French Polynesia: Exoclimenella maldivensis Duris & Bruce, 1995, Kemponia rapanui (Fransen, 1987) n. comb., Palaemonella crosnieri Bruce, 1978, P spinulata Yokoya, 1936, Periclimenaeus hecate (Nobili, 1904), P orbitocarinatus Fransen, 2006, Periclimenes aleator Bruce, 199 1, P paralcocki Li & Bruce, 2006, P uniunguiculatus Bruce, 1990, Pontonides loloata Bruce, 2005.

FIRST RECORD OF THE GEBIIDEAN GENUS AXIANASSA SCHMITT, 1924 (CRUSTACEA: DECAPODA: GEBIIDEA: AXIANASSIDAE) IN THE WEST PACIFIC, WITH DESCRIPTION OF A NEW SPECIES FROM THE SOUTH CHINA SEA

A new species, Axianassa sinica, from the Beibu Gulf (Gulf of Tonkin), northern South China Sea, is described and illustrated. The new species is readily distinguished from A. australis Rodrigues & Shimizu, 1992, by its acute rostrum, merus of pereopod 1 with a tooth distally on lower margin and an elongated telson.

Additional pandaloid shrimps from the South China Sea (Crustacea : Decapoda : Caridea), with description of one new species

The present paper reports 22 pandaloid shrimp species from the South China Sea and its adjacent area, including two new records of the South China Sea, 14 new records of the Nanshan Islands, and one new speices. Heterocarpus chani, new species, type localities from the Philippines and Nansha Islands, is distinguished from its allied species, H. gibbosus Bate, 1888, H. tricarinatus Alcock & Anderson, 1894 and H. lepidus De Man, 1917, by the third maxilliped with a short rudimentary exopod.

Further Indo-West Pacific palaemonoid shrimps (Crustacea : Decapoda : Palaemonoidea), principally from the New Caledonian region

Based on the material deposited in the Museum national d'Histoire naturelle, Paris, collected from the Indo-West Pacific, principally from the New Caledonian region, the present paper reports 117 palaemonoid shrimp species, which belong, respectively, to Anchistioididae ( one genus, one species), Gnathophyllidae ( one genus, one species), Palaemonidae Palaemoninae ( seven genera, nine species), and Palaemonidae Pontoniinae ( 30 genera, 106 species), including eight new species. The new species are all Pontoniinae: Mesopontonia brevicarpalis sp. nov., Palaemonella komaii sp. nov., Periclimenes crosnieri sp. nov., Periclimenes forgesi sp. nov., Periclimenes loyautensis sp. nov., Periclimenes paralcocki sp. nov., Periclimenes paraleator sp. nov., and Periclimenes pseudalcocki sp. nov. The last six new species are members of the deep-water "Periclimenes alcocki species complex'', which has more than two ( usually four) pairs of dorsolateral telson spines anterior to the posterior telson margin, the cornea is usually reduced, the dactyl of the major second chela is generally flanged and the chela is sometimes covered with small tubercles. The complex is usually found at more than 200m depth in the West Pacific. The species can be distinguished from each other by the armature of ambulatory propod and dactyl, diameter of cornea, rostrum shape and the number of pairs of dorsolateral telson spines. Mesopontonia brevicarpalis sp. nov., from the southeast coast of Africa, is the seventh species of the genus. Palaemonella komaii sp. nov. is very similar to Palaemonella dolichodactylus Bruce, 1991 and Palaemonella hachijo Okuno, 1999. These three species share the features of very long and slender ambulatory pereiopods with the dactyl more than eight times longer than its basal depth and with several long setae on the dorsal dactylar margin.

Aega sheni, a new species of Aegidae (Crustacea : Isopoda : Cymothoida) from southern China and Australia

Aega sheni sp. nov. from Chinese and Australian waters, is described and figured. This species is characterized by the plate-like expansion of antennule peduncle articles 1 and 2, very large eyes (nearly making contact), numerous robust setae on the inferior margins of the ischium of pereopods 2 and 3, large distal lobe on the propodus of pereopods 1-3, shape and setation of the uropods, and the rounded pleotelson posterior margin. Aega sheni has been recorded at depths of 300-435 metres.

On two species of euxanthine crabs from the South China Sea, including a description of a new species of Crosnierius (Crustacea : Decapoda : Brachyura : Xanthidae)

A new species of the previously monotypic xanthid genus Crosnierius Serene & Vadon, 1981 is described from the South China Sea. The species differs from Crosnierius carinatus Serene & Vadon, 1981 in the structure of the anterolateral teeth, ambulatory leg proportions and form of the male first pleopod. Paramedaeus planifrons (Sakai, 1965) is also reported from the South China Sea, the first record of the species outside its type locality of Japan.

On two species of spider crabs of the genus Doclea (Crustacea : Decapoda : Brachyura : Majidae : Pisinae) from China, one of which is new

A new species of spider crab, Doclea unidentata, is described from the South China Sea. Allied to D. brachyrhynchos Bleeker, 1856, and D. macracanthus Bleeker, 1856, it can easily be distinguished by its very short, unidentate rostrum. The identity of Doclea canalifera Stimpson, 1857, is resolved with the selection of a neotype, and it is here regarded as a senior subjective synonym of D. japonica Ortmann, 1893. The taxonomy of this species as well as the allied D. ovis (Fabricius, 1787) is also discussed.

On a new genus and new species of xanthid crab (Crustacea, Decapoda, Brachyura, Xanthinae) from the South China Sea, with notes on the genus Liagore De Haan, 1833

A new genus and new species of xanthid crab, Ovatis simplex, is described from the South China Sea. The genus is closest to Liagore but can be distinguished by a suite of carapace and male gonopod characters. The systematic position of Liagore is also considered, and both genera, Liagore and Ovatis, are here referred to the subfamily Xanthinae. Comparisons with the allied genera, Paratergatis and Pulcratis, are also provided.
