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 of Amblypomacentrus is described from the South China Sea off Vietnam. It differs from congeners in scale and gill-raker counts, slightly protruding snout, and coloration. This is the first record of this genus from the mainland Asia.

A New Species

A new species of scale-worm, Lepidonotopodium okinawae sp. nov. from the Okinawa Trough is described. The new species differs from the other species of Lepidonotopodium by having 24 segments and numerous foveolae on the surface of elytra with one globular micropapilla in every foveola. A new record of the mussel commensal Branchipolynoe pettiboneae Miura & Hashimoto, 1991 is reported and described from the northern South China Sea, where for the first time the scale-worm is noted as occurring at a cold-seep. Keys to distinguish the species of Branchipolynoe and Lepidonotopodium are provided.

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.
