中文摘要：采自广东湛江湾海域软水母亚纲(Leptomedusae Claus,1877)、锥螅水母目(Conica Broch,1916)、和平水母科(Eirenidae Haeckel,1879)、和平水母属(Eirene Eschscholtz,1829)2新种,即大腺和平水母新种(E.macrogonia Huang,Sun et Liu,sp.nov.)和湛江和平水母新种(E.zhanjiangensis Huang,Zhang et Zao,sp.nov.)。其鉴别特征如下:(1)大腺和平水母,新种;伞扁于半球形,胶质中等厚;胃柄基部塔状,胃柄较长,伸出伞腔口外;垂管长度短于口唇,4个发达口唇边缘呈齿状皱褶;生殖腺发达波状弯曲,着生于辐管下伞部,从胃柄基部延伸到伞缘外;19~24条缘触手,5~8个缘疣,触手基部呈球状,无排泄乳突;每2条触手间或触手和缘疣间有1个平衡囊,每个平衡囊有1~2个平衡石;4条辐管,1条环管。(2)湛江和平水母,新种;伞半球形,胶质厚;胃柄基部呈塔形,末端变窄;垂管较长,约等于口唇长度,口唇边缘有齿状皱褶;生殖腺带状,从胃柄基部延伸至近伞缘;缘触手多,70~125条,触手基球有排泄乳突;平衡囊数目约为触手数的1/2;4条辐管,1条环管。

外文摘要：The samples of Eirene were collected from the Zhanjiang Bay of Guangdong at 21°04′40.52″N 110°30′2.87″E during May,2010 and May 2016.Two new species of Eirene i.e.E.macrogonia Huang,Sun et Liu,sp.nov.and E.zhanjiangensis Huang,Zhang et Zao sp.nov.are decribed.All type specimens are deposited in College of Ocean and Earth Sciences,Xiamen University.The specific diagnoses of two new species are as follow:Eirene macrogonia Huang,Sun et Liu sp.nov.Unbrella nearly hemispherical;gastric peduncle long,exceeding beyond the velar opening,the base pyramidal shaped;with 4 radial canals and a ring canal;with 4 large sinuous gonads,from near the base of the peduncle to beyond the umbrella margin along the four radial canals with 19?24 marginal tentacles of the same size,its bulbs without excretory papillae,with 5?8 rudumentary bulbs.Eirene zhanjiangensis Huang,Zhang et Zao,sp.nov.Umbrella hemispherical,jelly think;the base of gastric peduncle pyramidal and the end narrow;lenth of manubrium near equal to the one of oral lips;4 gonads banding shaped,extending from the base of peduncle to near umbrella margin along the 4 radial canals;with 4 radial canals and a ring canal;with 70?125 marginal tentacles of the same size,its bulbs with excretory papillae;the number of statocysts about 1/2 of one of tentacles.
