Two new species of the deep-water spider crab genus Pleistacantha Miers, 1879, are described: P. griffini sp. nov. and P. maxima sp. nov. Pleistacantha griffini, from northwestern Australia and Indonesia, most closely resembles P. moseleyi (Miers, 1886), with which it has been confused. Pleistacantha griffini is readily distinguished from P. moseleyi based on carapace physiognomy, pereopod morphometrics and gonopod structure. Pleistacantha maxima, ranging from Japan to Australia, has been previously confused with the morphologically similar P. oryx Ortmann, 1893. The new species differs from P. oryx in numerous features, the most striking being a maximum body size exceeding twice that of P. oryx.

Commercial Harvesting

Members of the family Coralliidae, known as precious corals, are ecologically and economically important deep-sea or-ganisms. However, these organisms are currently threatened by commercial harvesting. In order to create and implementeffective conservative strategies, taxonomic knowledge of conservative targets is necessary, but unfortunately the taxon-omy of precious corals in this family is still ambiguous. This study provides a review of 15 Coralliidae species from thenorthern West Pacific region and a key to species identification. In addition, descriptions of two new species, Coralliumcarusrubrum n. sp. and C. taiwanicum n. sp., as well as a redescription of C. sulcatum Kishinouye, 1903 are included.Corallium carusrubrum n. sp. is distributed on seamounts off northeastern Taiwan. The autozooids of C. carusrubrum n.sp. are retractile and each can be fully withdrawn into the cortex thereby causing a mound on the surface which is shortand cylindrical rather than typically hemispherical; additionally, there are no long spindles in their tentacles. Coralliumtaiwanicum n. sp. is distributed in an area off southwestern Taiwan. It has special unique 8-radiates with an oval shapeand large projections. Corallium sulcatum is distributed from an area off southwestern Taiwan to western Japan. It hasbeen harvested and traded for decades, but there were no illustrations in its original description, hence a redescription of this species is provided.

A New Species

A new species ofPerisesarma,P. tuerkayi, is described from mangroves of Tan Thoi Island, southern Vietnam. Morphologically, the new species differs most significantly from congeners by the tuberculation pattern of the chelar dactylus, its unique G1 morphology, an unusually large maximum body size, and relatively short and broad ambulatory legs. Genetically,P. tuerkayin. sp. is markedly divergent from other congeneric species, both in mitochondrial and nuclear DNA. It is the fifth species ofPerisesarmareported from Vietnam.

Two scyliorhinid catsharks of the genus Halaelurus, H. sellus n. sp. and H. maculosus n. sp., are described from northwestern Australia and eastern Indonesia, respectively. The new species, which have been confused with H. boesemani (western North Pacific) and H. buergeri (northwestern Indian Ocean), have a colour pattern consisting of dark bars and dark spots but differ from these species by a combination of coloration, morphometrics, and meristics. These species differ from southern African endemics, H. lineatus and H. natalensis, in having a snout tip that is rounded rather than upturned. A related catshark Halaelurus quagga, from the northwestern Indian Ocean, has a colour pattern consisting of more numerous dark bars without spots.

First Descriptions

Two new species of Taeniacanthus Sumpf, 1871 (Copepoda, Taeniacanthidae) are described from filefishes (Monacanthidae) caught in the Indo-West Pacific region: T. brayae n. sp. from Pervagor melanocephalus (Bleeker) collected from five localities within the Central Indo-Pacific realm and T. mcgroutheri n. sp. from Monacanthus chinensis (Osbeck) and Paramonacanthus choirocephalus (Bleeker) caught off the Australian coast. Taeniacanthus brayae n. sp. and T. mcgroutheri n. sp. are distinguished from their congeners by the presence of an elongate terminal endopodal segment of the antenna, a spinulated terminal process and one seta on the maxillary basis, six elements on the terminal exopodal segment of legs 2–4 and an armature of II, I, 2 and II, I, 1 on the terminal endopodal segments of legs 2 and 3, respectively. Taeniacanthus brayae n. sp. can be readily distinguished from T. mcgroutheri n. sp. by having one row (rather than multiple rows) of spinules on the large pectinate process of the antenna, four setae (rather than three) on the maxillule and a 3-segmented (rather than 2-segmented) endopod on legs 2–4. New host and/or locality records for the taeniacanthids Cirracanthus monacanthi (Yamaguti, 1939), C. spinosus Dojiri & Cressey, 1987, Nudisodalis acicula Dojiri & Cressey, 1987 and Taeniacanthus aluteri (Avdeev, 1977) parasitic on triggerfishes and filefishes, as well as supplementary morphological information for the females and the first descriptions of the males of C. monacanthi, C. spinosus and N. acicula, are also included.

The Common

Two new jellyfishes are described from the waters off northwestern Australia. The first, Carukia shinju n. sp., is similar to the common Queensland Irukandji Carukia barnesi, but differs from the latter in having a larger body size, branched velarial canals, nematocyst warts on both the velarial canals and the perradial lappets, fully-spined tentacular nematocyst shafts, about 14 naked ringlets between adjacent tentacular nematocyst bands, and long, narrow, capitate rhopaliar horns. The second, Malo maxima n. gen. n. sp., is distinctive from other known cubozoan species by its unique combination of having a tall, narrow, robust body with a flattened apex; frown-shaped rhopaliar niche ostia; short, broad, straight rhopaliar horns; small, narrow pedalia with a single row of nematocyst patches on the outer keel and fine, cylindrical unmodified tentacles; moderately developed perradial mesenteries; 4 simple to bifurcated velarial canals per octant arising from a single base; and lacking both gastric phacellae and a thorn-like diverticulum of the pedalial canals. Both species are thought to be dangerous to humans, causing Irukandji syndrome.

A New Species

A new species of the genus Lycodon from the Gaoligong Mountains, Yunnan, China is described, Lycodon gongshan sp. nov. This species is similar to L. fasciatus, but differs in its longer tail, especially in males, and larger number of subcaudals, especially in females. The number of ventrals and maximum body size is greater in both sexes of the new species. From the Lycodon ruhstrati group, the new species differs in the colour of the belly and the dorsal bands. This new species seems to be endemic to Yunnan Province, People’s Republic of China. The holotype of Ophites fasciatus Anderson, 1879 appears to have been lost, so a neotype is designated in order to address the status of this taxon.

A New Species

Snakes in the Australo-Papuan elapid genus Oxyuranus are considered to be the most venomous species in the world. A recent expedition to the central ranges of Western Australia discovered a third species, which is described here from the only known specimen. Molecular genetic analyses using mitochondrial nucleotide sequences places the new species as the sister lineage of the two described Oxyuranus species, with all three species united by a long branch that also separates them from the nearest of the brown snakes species (Pseudonaja) to which the taipans are close relatives. Morphologically, the new species shares with the other Oxyuranus an undivided anal scale, high midbody scale row (21) and ventral scale (250) counts, but differs in having a single primary temporal scale and fewer lower labials (six). Maximum body size and venom potency are unknown. The discovery of a third species of taipan in the remote central ranges of Australia underlines the paucity of collecting from this region.

Abstract. A very diverse ostracod fauna was discovered in the latest Permian strata of the Dongpan section, southwestern Guangxi, South China. Fifty-one species belonging to twenty-eight genera were identified and described, including two new species (Bairdia dongpanensis n. sp. and Spinomicrocheilinella anterocompressa n. sp). This type of assemblage, with nineteen palaeopsychrospheric species and four pelagic species, is the first world-wide deep-water ostracod fauna reported from the latest Permian strata and the first one recorded in the Permian of China. The palaeoenvironmental analysis allows one to propose an evaluation of the bathymetry variation along the Dongpan section.
