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.

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。

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.

湛江港湾位于广东省雷州半岛东北部,海湾纵深60 km,湾外由硇洲岛、东海岛、南三岛形成天然屏障,湾域面积264.9 km2,湾内自然岸线长241 km,港内水深浪静,海域宽阔,航行和停泊条件良好,是集商港、军港、渔港和油港等于一身的我国南方深水良港。环湛江港湾的交通运输业、钢铁工业、石油加工业、港口物流业等较为发达,给湛江港湾的海洋生态环境带来较大的污染压力,为了了解港湾生态系统的健康状况,笔者等对湛江湾宝钢电厂脱硫海水受纳海域的生态环境和生物群落结构进行了系统的调查,以期查清海水酸化对海洋生态环境及生物群落结构的影响,为政府决策部门提供科学依据。
有关湛江湾浮游动物的研究最早始于沈嘉瑞和李茯香[1-2]的报道,近些年张才学等[3]、Wang等[4]、龚玉艳等[5]和姚少慧等[6]也对湛江湾浮游动物进行过研究,分析了湾内浮游动物的群落结构和季节变化及其影响因素。有关湛江湾水母类的研究,未见专门的报道。本文材料分别在2010年5月和2016年5月采集于广东湛江湾(21°04′40.52″N,110°30′2.87″E)海域,所采样品是用装有网口流量计的浅水Ⅰ型浮游生物网自底至表垂直拖网采集,以5%福尔马林溶液固定,于实验室体视显微镜下进行分类鉴定。通过对所采样品的分析,发现软水母亚纲(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.)。丰富了我国水母类的种类组成,为今后海洋生物资源调查和海洋环境监测提供参考。模式标本保存于厦门大学海洋与地球学院。
和平水母科Eirenidae Haeckel, 1879
(1)大腺和平水母Eirene macrogonia Huang, Sun et Liu, sp. nov.(图1
鉴别特征: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;垂管较短,口部有4个发达口唇,口唇边缘呈齿状;生殖腺发达,波状弯曲,着生在辐管下伞部,从胃柄的基部延伸到伞缘外;伞缘上有19~24条缘触手,5~8个缘疣,触手基部呈球状,无排泄乳突,每两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,缘膜中等宽。
描述:伞高2.5~3.5 mm,伞宽4.0~4.5 mm,伞扁于半球形,胶质中等厚,伞顶厚,伞缘薄;胃柄较长,伸出伞腔外,胃柄的基部塔状;垂管较短,口部有4个发达口唇,口唇边缘呈齿状;生殖腺发达弯曲,着生于辐管下伞部,从胃柄基部延伸到伞缘外;伞缘上19~24条缘触手,5~8个缘疣,触手基部膨大,近球形,无排泄乳突,触手短,上有分散的刺细胞;每两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,缘膜中等宽。
模式标本:正膜(GHU 006),副模(GHU 007008)。2010年5月,在湛江湾宝钢电厂沿岸海域(21°04′40.52″N,110°30′2.87″E)由广东海洋大学张才学等采集。
分布:中国广东沿岸海域。
词源:拉丁文macro-gonia意为大的生殖腺,指新种的生殖腺发达的特征而命名。
讨论:新种具有胃柄,伞缘无缘丝,触手基部无侧丝,4条辐管,1条环管,生殖腺位于辐管的下伞部分,没有向胃柄延伸,具有许多平衡囊,故属于水螅水母纲、软水母亚纲、锥螅水母目、和平水母科、和平水母属。
至今,世界已知和平水母属有24种[7-13],本新种的胃柄具有塔形基部,而胃柄具有塔形基部的种类有绿色和平水母[E. viridula (Péron & Lesueus, 1810)]、拟柄突和平水母(E. lacteoides Kuboda & Horita, 1992)、小手和平水母(E. parvidentculata Bouillon, 1984)、埃利和平水母(E. elliceana Agassiz & Mayer, 1902)、无疣和平水母(E. averuciformis Xu, Huang & Du, 2010)和柄突和平水母[E. lactera (Mayer.1990)]等6种。
绿色和平水母具有大小不同的触手;柄突和平水母和拟柄突和平水母胃柄的末端有4个间辐位的突起;小手和平水母口唇短于垂管,生殖腺在辐管中部有些扭曲,每2条触手间有4~6个缘疣和6个平衡囊;埃利和平水母生殖腺上有拟螅体子茎芽;无疣和平水母无缘疣,生殖腺棍棒状。本新种缘触手大小相同;胃柄的末端无间辐位的突起;口唇长于垂管;生殖腺发达,弯曲,伸出伞缘外,没有拟螅体子茎芽;触手19~24条和5~8个缘疣,这些特征不同于上述6种相似种(表1)。
(2)湛江和平水母Eirene zhanjiangensis Huang, Zhang et Zhao, sp. nov.(图2
鉴别特征:伞半球形,伞胶质厚;胃柄基部较宽,呈塔形,末端变细;垂管较长,其长度约等于口唇,4个口唇发达,边缘有锯齿状皱褶;生殖腺带状着生在下伞部辐管上,从胃柄基部延伸至近伞缘;缘触手70~125条,触手基球具排泄乳突;平衡囊数量约为触手数的1/2;每个平衡囊有1~2个平衡石;4条辐管,1条环管。
描述:伞高4.0~6.0 mm,宽8.0~12.0 mm,伞呈半球形,伞胶质厚,特别是伞顶,向伞缘逐渐变薄;胃柄基部较宽,呈塔形,末端变细;垂管较长,其长度约等于口唇长度,4个口唇边缘锯齿状皱褶;生殖腺带状,着生在下伞部辐管上,从胃柄基部延伸至近伞缘;缘触手70~125条,触手基部呈球状,有向轴的排泄乳突,触手细长,上有环状刺细胞,没有缘疣;平衡囊较少,其数目约为触手数的一半。每个平衡囊有1~2个平衡石;4条辐管,1条环管,缘膜中等宽。
模式标本:正模(GHU009),副模(GHU 010~025),2016年5月在湛江湾宝钢电厂沿岸海域(21°04′40.52″N,110°30′2.87″E)由广东海洋大学张才学等采集。
分布:中国广东省沿岸海域。
词源:新种是用采集地的地名命名的。
讨论:新种具有胃柄,无侧丝和缘丝,4条辐管,1条环管,生殖腺位于下伞部分的辐管上。具有许多缘触手和平衡囊,故属于水螅水母纲、软水母亚纲、锥螅水母目、和平水母科、和平水母属。
本新种胃柄具有塔形基部,故与上述新种大腺和平水母同样有6种的相似种,即绿色和平水母、拟柄突和平水母、柄突和平水母、小手和平水母、埃利和平水母和无疣和平水母。
本新种水母垂管长度约等于口唇,胃柄末端无间辐位突起,缘触手70~125条,大小相同,触手基球具排泄乳突;平衡囊数目约为缘触手数1/2,生殖腺带状,无拟螅体子茎芽;上述特征与6个相似种和大腺和平水母新种明显不同(表1)。
