Abstract The genus Xanthocalanus inhabits the intermediate and deep waters of the world ocean. The present study records and describes the first female individual of Xanthocalanus agilis Giesbrecht, 1893, collected in the South China Sea (13°0.21′N 113°0.21′E) at depths of 500-800 m. This species was identified by the following morphological characteristics: (i) rostrum with 2 slender filaments; (ii) posterolateral corners of fifth thoracic somite protuberant and triangular, reaching the posterior margin of genital somite; (iii) first segment of fifth pereiopod (P5) with a list of inner marginal spinules, distal segment short with 3 robust terminal spines. This finding expands the known global and vertical distribution of X. agilis.

Abstract The calanoid copepod Lucicutia hulsemannae Markhaseva & Ferrari, 2005 has, until now, only been recorded from the eastern tropical Pacific Ocean, i.e., in its description as a new species. The present study now reports L. hulsemannae for the first time from the southern basin of the South China Sea (7°59.57′N 113°0.1′E), at depths of 500-800 m. The main morphological characteristics of females of this species are: (i) Cephalosome with a pair of strong, triangular, lateral protrusions; (ii) plug of genital double-somite conical in lateral view, with swollen base; (iii) second urosomal somite significantly wider and shorter than third; (iv) inner marginal seta of second exopodal segment of fifth pereiopod (P5) thin towards its tip. This finding considerably expands the reported global distribution of L. hulsemannae, at the same time updating the checklist of copepods for Chinese waters.

A new deep water acrothoracican species, Weltneria acanthostoma sp. nov., has been discovered from the area of the Blue Ridge Seamount, South China Sea, at a depth of 534 m. A single female was found in a burrow in the scleractinian Madrepora oculata. This specimen is assigned to the genus Weltneria due to the possession of six pairs of cirri and two-joined caudal appendages. Weltneria acanthostoma differs from its congeners in the morphology of the slightly sinusoid opercular bars having hooked posterior processes and four or five curved, conspicuous, simple teeth, and by the absence of a calcareous formation of the attachment disk. The genus Weltneria exhibits a Tethyan relictual pattern in its geographical distribution. The diagnosis of Weltneria is based on symplesiomorphies and the genus may be a non-monophyletic taxon.

Military Balance

China’s massive arms buildups have exerted overpowering psychological effects over Southeast Asian countries. Yet, the world suffers the dearth of objective assessment of China’s warfighting capabilities, and is only ill-informed with partial impressionistic evaluation thereof that is based on the quantity of major platforms and weapons. In fact, China itself appears to have emphasized its military power in that manner, greatly having influenced the world perception on regional military balance of power in favor of China. Here, a Japanese perspective is of growing importance particularly because Japan in tandem with the U.S. has begun playing a larger military role of checking China in the South China Sea. This paper is an attempt to appraise the capabilities based on Japanese-language open source analyses of Japanese non-governmental experts and distill the Japanese strategic thinking in contrast to the Chinese counterpart. It is hoped that this work will enable further in-depth discussion that is underpinned on a cultural-philosophic understanding.

The South China Sea (SCS) has become the largest and the crucial Sea Lanes of Communication (SLOCs) not only for Southeast Asia but also for the world. As one of the claimants of the South China Sea, Philippines were always and will always be trying to protect its national interests in the disputed waterways as part of its national territory. This article discusses about the shift and continuity of the Philippines� foreign policy on the South China Sea issue. It explicates the shift and continuity of Philippines foreign policy under Rodrigo Duterte to the South China Sea. A more focus elaboration will be devoted on how the Philippines implemented its foreign policy to deal with China in the South China Sea dispute.It argues that Duterte foreign policy to this delicate issue is always based on the strategic dynamic of its �two-level game� (domestic and international political stimuli) to its national interests.

Abstract Abstract: The South China Sea (SCS) is one of the regions with the most dynamic and intense military activity in the world. This is largely due to commercial and political interests linked to the region, which is crucial for global maritime trade and rich in natural resources. China is the most interested party in the SCS, claiming 90% of its entire area, a portion referred to by Beijing as the “nine-dash line.” The present article seeks to analyse both quantitatively and qualitatively the influence of China on the military spending of four Southeast (SE) Asian countries that are also interested in the SCS: Vietnam, Malaysia, the Philippines, and Indonesia. For quantitative analysis, we used the data for military expenditure, armaments acquisition, the frequency and type of incidents involving national navies and/or civilians. For qualitative analysis, we retrieved information from hemerographic sources and official documents from the United States, China, SE Asian countries, the United Nations Convention on the Law of the Sea (UNCLOS), and the World Bank (WB).

Large Distribution

In this study we investigated 745 specimens of purpleback flying squid Sthenoteuthis oualaniensis across a large distribution range to investigate geographic, intraspecific and sexual variations in beak morphology. Beak morphometric variables showed significant spatial and intraspecific differences (P<0.05), with samples from the north-western Indian Pacific Ocean and the South China Sea having the largest and smallest beaks respectively. Multivariate statistical analysis indicated that the morphological characteristics of squid beaks would be useful for the identification of population structures and sex determination. Environmental conditions may be the major reason for variations in beak morphology between geographic populations throughout large distribution areas. In contrast, genetic differences may contribute to most of the intraspecific variation in beak morphology in the South China Sea. To address this clearly, further research needs to be done on morphology combined with genetic evaluation to compare methods of geographic and intraspecific population identification.

The world's turtles are decreasing at a rate which, if unchecked, could mean their extinction before the end of the century. In March this year a group of marine turtle specialists from all over the world met at IUCN headquarters in Switzerland to discuss what action could and should be taken. Professor Tom Harrisson, who is a specialist on the turtles of the South China Sea and Vice Chairman of the SSC Turtle Group, attended the meeting and drafted the first version of the agreed statement, the opening paragraphs of which are quoted at the beginning of this article, and the recommendations for action – ‘the now attack’ – at the end.
