摘　　要：报道台湾海峡软水母亚纲4个新种:网状卷丝水母Cirrholoveniareticulatan.sp.、宽胃拟触丝水母Paralove nialatigastern.sp.、带腺八管水母Octocannoidesteniogonian.sp.、和异手秀氏水母Sugiuraheterneman.sp.;4种我国首次记录:康德水母KantiellaenigmaticaBouillon,1978、柄杯螅水母HebelladissymetricaBillard,1993、芽侧丝水母HelgicirrhagemmiferaBouillon,1984、兰吉美螅水母Clytiarangircae(AgassizzandMayer,1902).对新种和新记录种类的形态特征进行详细描绘.并与近似种作了比较.In the present paper, samples of medusae collected from the upwelling region of Minnan-Taiwan Bank, Luoguan Bay, varied Island waters of Fujian from 1985 to 2001. Four new species of Leptomedusae were found, i.e. :Cirrholovenia reticulata n. sp., Paralovenia latigaster n. sp. Octocannoides taeniogona n.sp. Sugiura heternema n. sp., and four new records in China seas, i.e. :Kantiella enigmatica Bouillon, 1978(Laingiomedusae), Helgicirrha gemmifera Bouillon. 1984. Hebella dissymetrica Billrad,1933 and Clytia rangiroae (Agassizz and Mayer, 1902) (Leptomedusae). All type specimens are deposited in the Department of Oceanography. Xiamen University.Specific Characteristic of New Species1.Cirrholovenia reticulata n. sp. (Fig.1:3)At the present time only two species in Cirrholovenia is known, our new species differs from the other species to have umbrella with jelly thick, exumbrella covering reticular papillae; stomach small, square; four perradidal tentacles with large, triangular basal bulbs; five marginal cirri in each quadrant; four interradial marginal vesicles ; gonad cylindrical, along almost whole length of radial canals(see Tab.1).2.Paralovenia latigaster n. sp. (Fig.1:6)At the present time, only one species in the Paralovenia is known. The new species differs form P. bitentaculata Bouillon, 1984 by having Stomach fairly large, broad, with four radial lobes issued from 1/2 of the upsite of stomach wall, extending outwards along the radial canals, nearly umbrella margin; gonads on these lobes; two opposite perradial tentacles issued from two large marginal bulbs without cirri; other two small non-tentaclar bulbs with up to 12 lateral cirri; without rudimentary bulbs; without statocysts.3.Octocannoides taeniogonia n. sp. (Fig.2:8～9)This new species with eight simple radial canals; with eight marginal tentacles; with 3 short club-shaped ' tentaculae'between successive tentacles, all marginal bulbs with black pigmented spots on adxial position; with short and broad manubrium; mouth with eight simple lips; without
