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.

Abstract A deep-water coral forest, characterized by slender and whip-shaped bamboo corals has been discovered from water depths of 1200–1380 m at the western edge of the Xisha (Paracel Islands) area in the South China Sea. The bamboo corals are often accompanied by cold-water gorgonian “sea fan” corals: Anthogorgia sp. and Calyptrophora sp., as well as assemblages of sponges, cirrate octopuses, crinoids and other animals. The coral density increased toward the shallower areas from 24.8 to 220 colonies per 100 m2 from 1380 m to 1200 m water depth. This is the first set of observations of deep-water bamboo coral forests in Southeast Asia, opening a new frontier for systematic, ecological and conservation studies to understand the deep-coral ecosystem in the region.

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.
