Pelagic ostracods are one of the main groups of zooplankton and are abundant in marine ecosystems worldwide. The record of marine planktonic ostracod species in the central and southern part of the South China Sea accounts over for one-third of the total recorded marine planktonic ostracods in seas around China. In this study, we examined and compared the specimens from a recent cruise in this region that appeared to be different from previously described species of genusConchoecissa, and then confirmed them as a new bathypelagic speciesConchoecissa nigromaculatus. These specimens clearly differed from the other species of genusConchoecissawith differences observed in the size, carapace, locations of glands, mandible, maxilla, sixth limb, and furca. In this species, mandibular coxal endite has no ventral finger process, maxilla has prominently large endites and has only two claws on the tip, the sixth limb has very simple endites, and this species has distinctive features not previously observed in the tribe Conchoeciini before. It is therefore necessary to emend the diagnosis of this group.

ABSTRACT We detected and characterized two distinct scuticociliate ciliates inside Acropora corals in the South China Sea. One, voraciously foraging on Symbiodinium, resembled the brown band disease of ciliates. The other, which is closely related to Paranophrys magna, grazed on detritus instead of Symbiodinium. These two ciliates may serve contrasting functions (competitor versus “cleaner”) in the coral-ciliate-Symbiodinium triangular relationship.

Abstract There are many studies on the history of the islands in the South China Sea. The present article looks at the references to these islands in one source, Huang Zhong’s 黄衷 Hai yu 海語 (preface 1536). This mainly concerns two entries in that work. One entry bears the title Wanli shitang 萬里石塘, the other is called Wanli changsha 萬里長沙. The article presents English translations of these entries together with detailed comments. These comments are necessary because both entries contain several terms and passages that are difficult to understand. The comments investigate questions related to the geography and other phenoma of this area. This involves citations from contemporary sources as well as from some earlier and later works. In that sense the article may classify as a long philological note, or a collection of glosses, on a particular aspect described in one important mid-Ming text.

Ototyphlonemertes longissima sp. nov is described from the South China Sea. The present species, up to 158 mm long, is about three times longer than the longest previously reported individual known in the genus. It possesses a narrow stylet basis, a bulbous proboscis diaphragm, a long middle proboscis chamber, sculptured stylets, polygranular statocysts and excretory tubules, and thus belongs to the O. macintoshi species group. The genetic divergence (average uncorrected p-distance) between O. longissima (representing a unique network in TCS analysis) and the other species (TCS networks) of genus Ototyphlonemertes is 0.135–0.185.

A new species of the genus Mantisgebia Sakai, 2006, M. multispinosa sp. nov., collected from the South China Sea, is described and illustrated. It is readily distinguished from the other three species of the genus by the numerous spines on the cervical groove, hepatic region, and lower margins of the antennular and antennal peduncles.
