摘　　要：报道了2009年5月在粤东-闽南上升流区发现软水母亚纲（Leptomedusae Haeckel,1866）一新种,大腺触丝水母（Lovenella macrogonaLin,XuetHuang,sp.nov.）和我国海域一新记录,脆弱似杯水母[Phi-alella fragilis（Uchida,1938）].大腺触丝水母,新种的鉴别特征如下：伞半球形,外伞上有分散刺细胞,4个大的生殖腺,卵圆形,在辐管中部;4条主辐触手,触手球背部有块状黑色素,具有6~8对侧丝;4个大的间辐位缘疣,球形,具排泄乳突,背部有黑色素分布;24个平衡囊,每个平衡囊具1个平衡石.Samples of Leptomedusae were collected from the upwelling area of the east Guangdong and south Fujian coast waters at 21.6°～24.3°,115.7°～118.7° on June,2009.One new species and one new record in China of Leptomedusae,i.e.Lovenella macrogona Lin,Xu et Huang,sp.nov.and Phialella fragilis（Uchida,1938） are described in the present paper.The specific diagnosis of Lovenella macrogona sp.nov.is as follows：Umbrella hemispherical,with scatted nematocysts on umbrella;four large egg-shaped gonads on the middle radial;four perradial marginal tentacles,with a black pigmented patch along the abaxial bulbs,each flanked by six to eight pairs of lateral cirri;four big interadial marginal warts,spherical shape,with excretory papillae and black pigmented patches on the abaxial bulbs;24 statocysts,each with one concretion.
