About 50 nemertean species have been reported to live in symbiotic relationships with other invertebrates, but only two hoplonemertean species are associated with echinoderms (starfish). The palaeonemertean Cephalotrichella echinicola, sp. nov. is described from samples collected in Nha Trang Bay, Vietnam, South China Sea. The species is the first known nemertean associated with sea urchins (Metalia sternalis and M. spatagus), living on both the oral and the aboral surfaces of the host and freely moving among its spines. The internal morphology of the new species is described based on histological sections and confocal laser scanning microscopy with phalloidin and antibody labelling. Sequences of three nuclear gene markers (18S rRNA, 28S rRNA, and histone H3) and two mitochondrial gene markers (16S rRNA and COI) were compared with those of other palaeonemertean species, and a phylogenetic analysis suggested that C. echinicola is closest to the free-living Cephalotrichella alba Gibson & Sundberg, 1992. Both the morphological data and the phylogenetic analysis provide additional evidence for distinguishing the families Cephalotrichidae and Cephalotrichellidae and support the rejection of Cephalotrichella as a junior synonym of Cephalothrix. A new diagnosis of the genus Cephalotrichella is given. http://zoobank.org/urn:lsid:zoobank.org:pub:091B5D56-71B2-4F4C-9AD8-F666B4610DE2

Sipunculan worms from the Vietnamese waters are still poorly investigated, while they are well known from Chinese andTaiwanese waters of the South China Sea. During the years 2008–2010, therefore, we collected sipunculans from NhaTrang Bay in South Vietnam. Twenty species of peanut worms representing eleven genera and five families of the phylumSipuncula are recognized from more than one thousand individuals collected from various biotopes. Fifteen species arenew records for Nha Trang Bay with Nephasoma pellucidum being a new record for the South China Sea. Species accountsinclude the most important taxonomic characters as well as quantitative characteristics, distributions, and specific biotopedata. All species were illustrated in living conditions with everted introvert and tentacular apparatus. Accordingly, a key up to species level is provided.

Colony Fragment

A new species of Eleutherobia is described, enlarging the Eleutherobia species group that lack sclerites in the anthocodiae. The Octocorallia of the South-China Sea are poorly known, and the data that is presented provides a new record of the genus for Vietnam. The original description of Sinularia manaarensis Verseveldt, 1980 was based on a single incomplete colony fragment collected in 1902 near Ceylon (Verseveldt, 1980, Pl. 16, Fig. 3). Here we present data on both living and preserved S. manaarensis colonies that were found in Nha Trang Bay (South China Sea) in 2006. The club-shaped surface sclerites with wide flattened handles are characteristic of the species. Images of live colonies are given along with a biogeographical discussion. S. arctium sp. nov., is also described. It has a remarkable assortment of sclerites, which includes both leptoclados- like clubs and warty clubs with a distinct central wart.
