摘　　要：报道2007年1～2月在东海和2006年6～7月在台湾海峡南部发现的花水母亚纲（Anthomedusae Haeckel，1879）高手水母科（Bougainvillidae Lütken，1850）单肢水母属（Nubiella Bouillon,1980）一个新种——中华单肢水母N．sinica sp．nov．和2006年7～8月在北黄海发现软水母亚纲（Leptomedusae Haeckel，1866）侧管水母科（Dipleurosomatidae Russell．1953）侧管水母属（Dipleurosoma Boeck，1866）-新记录——正型侧管水母D．typicum Boeck,1866．In this paper, the samples of Hydromedusae were collected by research vessels from the East China Sea（25. 178°- 38. 646°N, 119. 967° - 128. 621° E） during January - February 2007, from the north Yellow Sea （36. 950° - 38. 273° N, 120. 869°- 124. 250°E）during July-August 2006 and from the south part of the Taiwan Strait（21. 183°-23. 633°N,116. 000°-118. 933°E）during June-july,2006. Through the analysis of 209 samples, one new species i. e. Nubiella sinica sp. nov. and one record in China Seas i. e. Dipleurosoma typicum Boeck, 1866 are described. All type samples are deposited at the Department of Oceanography,Xiamen Umverslty. Nubiella sinica sp. nov. has simple unbranched oral tentacles, arising above mouth rim, with 4 perradial marginal bulbs and 4 solitary marginal tentacles, no oeelli, placing this medusa in the family Bongainvillidae Lütken, 1850,genus Nubiella Bouillon, 1980. N. milra： umbrella with a thick conical apical projection, exumbrella without scattered cnidocysts, manubrium cylindrical, 2/3 umbrella cavity height,with a small gastric peduncle, with 4 oral tentacles, gonads encircling manubrium, with medusary buds in a- bove of manubrium,with 4 marginal tentacles,each distal half thicker and armed with scattered cnidocysts, 4 marginal bulbs small, spherical, same size and structure. N. paramitra：umbrella with a conical apical projection, with scattered cnidocysts, manubrium cylindrical, 1/3 umbrella cavity height, with a short gastric peduncle,about 1/4 of length of manubrium, with 4 oral tentacles,gonads completely surrounding manubrium,no medusa-buds, 4 marginal tentacles, each arising above half of marginal bulbs, covered ring cnidocysts, 4 marginal bulbs small,erect elliptical-like,same size and structure. N. sinica sp. nov. ： umbrella without apical projection,with a long gastric peduncle,manubrium without medusary buds,with 8~ 16 oral tentacles and marginal bulbs nearly spherical, tentacle not arise above half of marginal bulbs. So the new species is diff
