摘　　要：材料系于2007年(1,4,7,10月)、2008年(1,7月)和2009年(1月)在北部湾水域采集的,调查海区共设52站,共采集364份样品。经分析鉴定出67种水母,其中有3新种和中国2新纪录,主辐特古水母Tregouboiva perradialis Xu,Huang et Du,sp. nov.,泡真囊水母Euphysora vacuola Xu,Huang et Guo,sp. nov.,波腺侧丝水母Helgicirrha sinuatus Xu,Huang et Du,sp. nov.,艾格帝纹水母Timoides agassizi Bigelow,1904和大腺美螅水母Clytia macrogonia Bouillon,1984。此外,还报道了20种水母为北部湾新纪录。模式标本保存在中国水产科学研究院南海水产研究所。主辐特古水母,新种Tregoubovia perradialis Xu,Huang et Du,sp. nov.鉴别特征伞近钟形,外伞有16条双层向心肋; 垂管很大,近方形,约为内伞腔深度4/5;口有4个延长成触手状的口唇,具环状刺胞,无末端刺胞球;隔膜短;4个大的椭圆形生殖腺,几乎覆盖整个垂管主辐位;伞缘无缘触手或缘基球;无眼点。正模(BG 001),北部湾S30站(17°30'N,107°30'E;水深70m),2008-07-06,梁新采(南海水产研究所)。词源:新种种名源自拉丁词perradialis,意为生殖腺位于垂管主辐位。泡真囊水母,新种Euphysora vacuola Xu,Huang et Guo,sp. nov.鉴别特征伞有钝圆形顶突;垂管长椭圆形,约有1/2长度超出缘膜口外,垂管基部很宽,覆盖着浓密泡状细胞组织;4条辐管上部与扩大的垂管基部连接;生殖腺围绕着垂管壁;主触手很长,触手基球很大,呈卵圆形至球形,触手上具30～40个成排的背轴刺胞球,无末端膨大刺胞球,另3个触手基球退化,很小,同样大小,无丝状触手,每个基球具外胚层背距。正模(BG 006),北部湾C15站(20°N,109°E;水深44m),2007-07-25,梁新采(南海水产研究所)。副模(TB001),台湾海峡102站(23°40'N,118°44'E;水深54m),1988-06-29,黄加祺采(厦门大学海洋学系)。词源:新种种名源自拉丁词vacuola,意为该种在垂管基部覆盖浓密泡状细胞组织。波腺侧丝水母,新种 Helgicirrha sinuatusMedusae from the Beibu Gulf, in the Northern South China Sea, are described from 364 samples collected during seven seasonal oceanographic censuses fromJan., Apr., July and Oct. 2007, Jan. and July 2008, andJan. 2009. A total of 67 species were identified, three of which are new to science： Tregoubovia perradialis sp. nov., Euphysora vacuola sp. nov., and Helgidrrha sinuatus sp. nov. Two species are new records for Chinese waters, i. e. Timoidess agassizi Bigelow, 1904 and Clytia macrogonia Bouillon, 1984, while 20 species are new records for the Beibu Gulf. The types are deposited in the South China Sea Fisheries Research Institute, Chinese Academy of Fishery Science.
