摘　　要：记述了采自南海北部软水母亚纲(Leptomedusae)多管水母科(Aequoreidae)多管水母属(Aequorea)2个新种:龚氏多管水母(A.gongqiuhongae sp.nov.)和拟四手多管水母(A.paratetranema sp.nov.),模式标本保存于厦门大学海洋与地球学院.详细记述了2种多管水母的形态特征,并与相似种进行比较,可为今后海洋生物调查提供参考.Samples of zooplankton were collected from the northern South China Sea in July 2004 and July 2005,and from the Daya Bay in April 2018,respectively,and analyzed.Two new species of aequorid,Aequorea gongqiuhongae sp.nov.and A.paratetranema sp.nov.were described.All type specimens were deposited at College of Ocean and Earth Sciences,Xiamen University.In this study,the morphological characteristics of these two new species were described,and compared with those similar species.These new findings may provide a reference for future marine biological investigations.A.gongqiuhongae sp.nov.(Fig.1):6-7 mm high,13-14 mm wide,hemisphere,thin in the center;the stomach about 1/3 as wide as the umbrella;the mouth large,with many filiform lips,about 2 times as many as the radial canals;gonads waving-shaped,extending from the stomach to the middle of radial canals;32-52 tentacles without excretory papillae,one small bulb and 2-5 statocysts between successive tentacles.A.paratetranema sp.nov.(Fig.2):2.0 mm high,3.5 mm wide;the stomach about half as wide as the umbrella;lips about half as many as the radial canals;29 radial canals,including 12 rudimentary radial canals;gonads ovalis;4 conical tentacles with pigmented spots;28 bulbs with pigmented spots and 32 statocysts.
