A New Species

Ostracods are one of the major groups of marine benthos, inhabiting virtually all oceanic environments worldwide, and a total of 31 species have been recorded in genus Euphilomedes Kornicker, 1967. In the present study, we describe a new species Euphilomedes biacutidens collected from the Taiwan Strait and South China Sea. E. biacutidens sp. nov. differs from the related species of the genus Euphilomedes in having a unique combination of the characteristics of spines on carapace, the filaments on sensory seta, the arrangement of setae on tip of the first antenna, the numbers of setae on appendages, the claws on fifth limb, the teeth on the comb of the seventh limb and furcal claws. It is particularly obvious that it has a bifurcated and pointed ventral corner of the rostrum, two spines on the posterior margin of right valve, a row of teeth along the inner margin of article 3 of the endopod of the second antenna, and some long claws instead of setae on the fifth limb.

A New Species

A new species of halocyprid ostracod,Bathyconchoecia liui, from the bathypelagic zone of the Nansha Trough (North-West Borneo Trough, southern South China Sea) is described and illustrated. It is compared with the closely similar speciesB. angeliGeorge, 1977. The present species is easily distinguished fromB. angeliby the structures of the toothed edges of the mandibular basis and coxa, and by the segmentation of the fifth limb.

A New Species

Abstract Eucalliaxiopsis liui sp. nov. is described from a specimen taken from the South China Sea. The new species differs from other species of Eucalliaxiopsis in the combination of a telson with a transverse posterior margin, without a transverse row of spiniform setae, and a hook on the upper margin of the carpus of the cheliped. Eucalliaxiopsis liui is unique in having a biramous female pleopod 2, its endopod slender, with finger-like appendix interna, and a slender segmented exopod.

A New Species

Abstract A new species of the copepod genus Stygiopontius is described based on samples from a cold seep in northeastern South China Sea southwest to Taiwan, which were collected by the ROV Faxian with its mother vessel R/V Kexue in September 2017. The copepods were obtained by washing Shinkaia crosnieri Baba & Williams, 1998 (Decapoda: Munidopsidae) caught at a depth of 1124 m. The new species can be distinguished from its congeners by the combination of the following characteristics: caudal rami about 3.5 times as long as wide; basis of maxilliped with plumose seta, endopodal claw of maxilliped stout, with a row of fine spinules on inner margin; coxa of leg 1 with one inner seta; basis of leg 1 with stout spine exceeding to end of first endopodal segment; second endopodal segment of female leg 4 with pointed process; third exopodal segment of leg 4 with three outer spines. This is the first record of a Stygiopontius species from a cold seep.

A New Species

Grateloupia tenuisWang et Luan sp. nov. is a new species described from Lingshui, Hainan Province, South China Sea. Based on the external form and internal structure, combined withrbcL gene sequence analysis,Grateloupia tenuisis distinct from otherGrateloupiaspecies as follows: (1) thalli is slippery and cartilaginous in texture; possess fewer branches, relatively slight main axes, and two or three dichotomous branches; (2) cortex is 5-6 layers; medulla is solid when young, but hollow in old branches; reproductive structures are dispersed in main axes of thalli and lower portions of branchlets; exhibitsGrateloupia-type auxiliary cell ampullae; (3) the four studiedG. tenuissequences were positioned in a largeGrateloupiaclade of Halymeniaceae, which included sister group generitypeG. filicinawith 68 bp differences;G. tenuiswas determined to be a sister taxon to theG. catenata,G. ramosissima,G. orientalis, andG. filiformissubclade. The pairwise distances betweenG. tenuisand these species were 39 to 50 bp. The sequences ofG. tenuisdiffered by 81–108 bp from the sequences of other samples inGrateloupia; there are 114–133 bp changes betweenG. tenuisand other genera of Halymeniaceae. In final analysis, we consideredGrateloupia tenuisWang et Luan sp. nov. to be a new species of genusGrateloupia.

A New Species

A new species, Michaelcallianassa sinica, from the Beibu Gulf (Tonkin Gulf), northern South China Sea, is described and illustrated. The new species is readily distinguished from M. indica Sakai, 2002, the type species of the genus, by its short uropodal endopod and exopod, and elongated carpus of the minor cheliped.
