【摘要】 记述了采自南海的棒状水母科Corymorphidae Allman,18721新属,肋突水母属Costa Huang,Xu et Lin,gen.nov.,2新种,即南海肋突水母Costa nanhaiensis Huang,Xu et Lin,sp.nov.,间腺梅尔水母Mayeri intergona Huang,Xu et Guo,sp.nov.和1新纪录种,幼芽真囊水母Euphysora gemmifera Bouillon,1978。详细描述其形态特征,并绘图与本属其它种进行比较,模式标本保存于国家海洋局第三海洋研究所。

【Abstract】 Samples of Corymorphidae were collected from the South China Sea(4°-18° 30’ N,109° 119°E),during Aug.2011.Based on the taxonomic system of Bouillon et al.(2006),at present time 12 valid genera of Corymorphidae are known,Euphysora M aas,1905 and Vannuccia Brinckmann-Voss,1967 are valid genera.In view of the used of the genus name of Vannuccia M arcus,1948,we wish to make the proposal of which the genus name of Vannuccia BrinckmannVoss,1967 is change to that of Mayeri Xu,Huang et Guo,gen.nov.,remembering the first author for the species of the genus.One new genus,Costa Huang,Xu et Lin,gen.nov.,two new species,i.e.Costa nanhaiensis Huang,Xu et Lin,sp.nov.,Mayeri intergona Huang,Xu et Guo,sp.nov.and one new record,Euphysora gemmifera Bouillon,1978 are described.All type specimens are deposited in the T hird Institute of Oceanography,SOA.T he specific diagnoses of one new genus and two new species are as follows.Costa Huang,Xu et Lin,gen.nov.Umberlla dome-shaped,exumbrella with 4 longitudinal ridges and ribs;manubrium large,the length no extending umbrella margin;mouth simple,circular;one well-developed solid tentacle terminating in large cnidocyst knob,3 marginal bulbs without tentacles;4 radial canals,1 circular canal;with mesenteries.T ype species:Costa nanhaiensis Huang,Xu et Lin,sp.nov.Etymology.T he genus name from Latin Costa,means rib and ridge,the new genus exumbrella with 4 longitudinal ridges and ribs.Costa nanhaiensis Huang,Xu et Lin,sp.nov.(Figs 1-2) Umbrella dome-shaped,exumbrella with 4 longitudinal ridges and ribs;manubrium large,extending no beyond umbrella margin,vacuolated endodermal cells in the upper part,gonads in the lower part;one well-developed solid tentacle terminating in two large cnidocyst knobs;3 marginal bulbs without tentacles;4 radial canal,1 circular canal;with mesenteries.Etymology.Form Latin,Nanhaiensis,means Nanhai,the species name refers to the first collected from Nanhai(the South China Sea).Mayeri intergona Huang,Xu et Guo,sp.nov.(Figs 3-4) Umbrella dome-shaped,without apical process,bell margin slightly asymmetrical;manubrium short,length about 1 /3 of the umbrella cavity,with a apical chamber;gonads global shaped,in interradial position of manubrium;one swollen marginal tentacle,hollow for half its length and ending in long,large,clubshaped swelling armed with cnidocysts.
