Three species of the genus Acanthochitona Gray, 1821, two of which are rare [A. intermedia (Nierstrasz, 1905) and A. saitoi Sirenko, 2012] and one is new to science (A. spratlyenses sp. nov.), have been collected off the Spratly Islands in the South China Sea, known also as the Truong Sa Islands. Colour and SEM photographs are given for all three species. The new species belongs to the group of acanthochitons that inhabit shoals of Vietnam, the Ryukyu Islands and the Spratly Islands. This group is characterised by the absence of a distinct border between the jugal and pleurolateral areas and merged pustules on the jugal area of the intermediate valves.

Petroleum Development

Joint petroleum development has often been considered as a viable solution to the seemingly intractable Spratly Islands dispute in the South China Sea (SCS). This is, however, more easily said than done. On the other hand, little attention is paid to fisheries co-operation in the SCS despite the fact that fisheries constitute an important part in the economies of coastal states. The present laissez-faire approach to fisheries in the disputed area gives rise to friction and tension. By highlighting the salient features of existing fisheries’ co-operative arrangements in the world, this article demonstrates the merits of a fisheries arrangement in the SCS. It also argues that fisheries co-operation, as a low-profile undertaking, is probably easier to achieve than joint petroleum development. A fisheries arrangement would serve the immediate interests of parties to the Spratly Islands dispute and may pave the way for their future high-profile co-operation, i.e. joint petroleum development.

© 2019 Japanese Society of Phycology Flattened Gracilaria species are widely distributed along the coasts of the South China Sea with more than 20 species recorded. Within the South China Sea, Gracilaria mammillaris has only been reported from Vietnam, but this species is likely restricted to the western Atlantic. This study aimed to reevaluate the taxonomic status of Vietnamese specimens of ‘G. mammillaris’ using combined morphological and molecular data. Our data clearly indicated that Vietnamese specimens were morphologically and genetically distinct from authentic G. mammillaris from the western Atlantic, and also other described flat Gracilaria species. We, therefore, propose that specimens from Vietnam originally identified as G. mammillaris be designated as a new species, Gracilaria phuquocensis sp. nov. Morphologically, G. phuquocensis can be distinguished from other flat Gracilaria species by its small thallus size, narrower blades, many medullary layers, abundant basal nutritive filaments within mature cystocarps, and tetrasporangial nemathecium. Our rbcL sequence analyses showed that the new species was sister to Gracilaria rhodymenioides from Thailand, and these two species formed a clade with cylindrical Gracilaria species. Our study contributes to clarification of the taxonomic status of misidentified specimens attributed to the flattened Gracilaria species in the South China Sea.

The diagnosis of the recently described hermit crab genus Catapaguropsis Lemaitre & McLaughlin, 2006 is emended to accommodate a second distinctive new species, Catapaguropsis brucei n. sp., which does not exhibit the sexual dimorphism described for the type species, C. queenslandica Lemaitre & McLaughlin, 2006. Catapaguropsis brucei n. sp. is characterized by the marked reduction, in both sexes, of the posterior portions of the pleons, uropods, and telsons that are encased by cnidarians. In addition to the description and illustrations, this new species is compared and contrasted with species of other pagurid genera that occupy atypical carcinoecia.

AbstractCucullanus hainanensis sp. nov., collected from Muraenichthys gymnopterus (Bleeker) (Anguilliformes: Ophichthidae) in the South China Sea, was described using both light and scanning electron microscopy. The new species can be readily distinguished from its congeners by the large pseudobuccal capsule, the position of excretory pore and deirids, the length of spicules (0.64–0.76 mm, 5.84–6.67% of body length) and gubernaculum (0.21–0.24 mm), the number and arrangement of caudal papillae and the particular morphology of cloacal region in male. The new species was also characterized using molecular methods by sequencing and analysing the small subunit (18S) and the second internal transcribed spacer (ITS-2) of nuclear ribosomal DNA (rDNA). In addition, Cucullanus muraenesocis (Yin et Zhang, 1983) was regarded a homonym of C. muraenesocis Yamaguti, 1961, and a new name, Cucullanus wangi nom. nov. was given to it.

Collections of sphaeromatids from the northern and western South China Sea are reported. As a result of this study, the number of sphaeromatid species known from this sea has been more than tripled. Descriptions and illustrations of four new species (Dynoides harrisoni, Cerceis sinensis, Paracerceis holdichi and Paraleptosphaeroma brucei) from the South China Sea are presented, a new genus, Chitonosphaera, is erected for Gnorimosphaeroma lata Nishimura, 1968, and records are presented for a further 24 species.
