摘　　要：从海南五指山的大绿臭蛙Ranalivida膀胱内检获多盘科Polysto matidae双睾虫属Diplorchis单殖吸虫1新种,以宿主种名命名为大绿臭蛙双睾虫Diplorchis lividae sp.nov.。新种以肠支侧突明显而区别于蛙双睾虫、拉氏双睾虫和无指盘臭蛙双睾虫;与石林双睾虫的区别是本种的肠支末端进入后吸器;本种中央大钩的形状与杭州双睾虫的大钩基部具深裂的缺刻明显不同;与黑斑蛙双睾虫的区别是本种中央大钩的内突上附有向前延伸的长条形肌腱,另本种卵巢较小、长度与卵相近,而黑斑蛙双睾虫的卵巢长度超过卵长的一倍。本种为海南多盘类单殖吸虫的首次报道。模式标本保存于华南师范大学生命科学学院鱼类寄生虫研究室。Diplorchis lividae sp. nov. is described as a new species of the Polystomafidae （Monogenea）, parasitic in the urinary bladder of Rana livida （Amphibia） collected from Wuzhishan Town of Hainan Island. Its general morphology is similar to that of other members of the genus, but it is distinguished from closely related species by a combination of characters （Table 1 ）. It differs from Diplorchis ranae Ozaki, 1931, D. latouchii Zhang ＆ Long, 1987 and D. grahami Fang et al., 2007 by its intestinal caeca with obvious diverticula, and differs from D. shilinensis Fang et al., 2005 in its intestinal caeca reaching to posterior end of body and extending into haptor. It is distinguished from D. hangzhouensis Zhang ＆ Long, 1987 by the shape of hamuli, and from D. nigromaculatus Lee, 1936 by its inner root of hamuli armed with a long muscular band and also by the smaller size of its ovary compared to egg. This is the first species of polystomafid monogenean to be described from the amphibians of Hainan Island. Etymology. This new species is named after the name of the host. Holotypc No. HNWZS20060716-1, paratypes Nos. HNWZS20060716-2-9; Wuzhishan Mountain. （18°38＇-19°02＇N, 109°19＇-109°44＇E）, Hainan Island, 16 July 2006.
