| 摘 要： | 记述了采自台湾海峡侧丝水母属(Helgicirrha Hartlaub,1909)——卵形侧丝水母,新种(H.ovalis sp.nov.)和采自邻近海域厦门同安湾似杯水母属(Phialella Brown,1902)——厦门似杯水母,新种(P.xiamenensis sp.nov.).这2种鉴别特征如下:卵形侧丝水母,新种,伞扁于半球形,伞薄;胃柄短;生殖腺卵圆形,位于辐管近中部;8条触手,每条触手有3对侧丝,无排泄乳突;每2条触手间1～2个缘疣,各具1对侧丝,其末端有黑色素.厦门似杯水母,新种,伞扁于半球形,伞薄;胃小,口方形;生殖腺球形或椭圆形,悬挂于辐管近伞缘,有中沟;16条空心触手,触手基部球形;8个平衡囊,在伞缘环管垫状疣突上. |

| Abstract: | The samples of Leptomedusae were collected from the Taiwan Strait at 20.849°～27.056°N,114.920°～121.241°E in December 2007 and from Tong′an Bay of Xiamen at 24.562°～24.634°N,118.104°～118.180°E in May 2009.Two new species of Leptomedusae,i.e. Helgicirrha ovalis sp. nov. and Phialella xiamenensis sp. nov. are described after analyzing 131 samples.All type specimens are deposited in Third Institute of Oceanography,SOA.The specific diagnoses of the two new species are as follows:Helgicirrha ovalis sp. nov. Umbrella flatter than hemispherical,jelly thin,peduncle short,with four big oval gonads near middle of radial canals,8 tentacles with three pairs of lateral cirri,1～2 marginal warts each with one pair of lateral cirri between two tentacles,with black spot on its extreme tip.Phialella xiamenensis sp. nov. Umbrella flatter than hemispherical,jelly thin and soft,stomach short,mouth quadrate,four global or ellipse gonads hang on near marginal radial canals,with median groove,16 hollow marginal tentacles with eight closed marginal vesicles. |
