摘　　要：该文报道了寄生于五带豆娘鱼Abudefduf vaigiensis和六带豆娘鱼Abudefduf sexfasciatus鳃上的新海盘虫属2新种.广东新海盘虫,新种Neohaliotrema guangdongensis sp.nov.与贝氏新海盘虫Neohaliotrema bychowskii Zhukov,1976和双曲片新海盘虫Neohaliotrema dicurvilamellatum Li&Li,2000的中央大钩和交接管相似,但新种背中央大钩内突端部具有一"C"形的附片,支持器呈勺状,而贝氏新海盘虫的支持器位于交接管的末端,呈片状,双曲片新海盘虫支持器呈"6"字形,前后两端几丁质向内侧卷折.澳头新海盘虫,新种Neohaliotrema,aotouensis sp.nov.与细小新海盘虫Neohaliotrema gracilis Zhukov,1976和拉氏新海盘虫Neohaliotrema nagibinae Zhukov,1976后吸器的形状较为相似,但新种背中央大钩在内突端部有2个尖状凸,腹中央大钩内突上具有1个"U"形的附片,背联结片中央后缘后凸,腹联结片中部有2个耳状突而与已知种不同,其次,新种交接管(长0.018～0.024mm)明显短于细小新海盘虫的交接管(长0.045～0.058mm)和拉氏新海盘虫的交接管(长0.030～0.031mm),支持器宽片状,从基部延伸到交接管的1/2～2/3处,而细小新海盘虫交接管末端呈"C"形,支持器位交接管的末端,呈弯曲的三角形,拉氏新海盘虫的支持器结构不易发现.Two new species are described,which are of the genus Neohaliotrema Yamaguti,1965,parasiting in the gills of Abudefduf vaigiensis （Quoy et Gaimard,1846） and Abudefduf sexfasciatus （Cuvier et Valenciennes,1830）.The central anchors and the copulatory of Neohaliotrema guangdongensis sp.nov.are similar to that of Neohaliotrema bychowskii Zhukov,1976 and N.dicurvilamellatum Li Li,2000,but different with a C-shaped piece attached on the top of inner root of dorsal central anchors and with a ladle-shaped supporting apparatus,while the supporting apparatus of N.bychowskii is piece-shaped and that of N.dicurvilamellatum is ＂6＂ shaped,convoluted inside around both chitinous sides.Neohaliotrema aotouensis sp.nov.is similar to Neohaliotrema gacilis Zhukov,1976 and Neohaliotrema nagibinae Zhukov,1976 in the shape of haptor,but the new species differs from the known species with two sharp-shape raised on the top of inner root of dorsal central anchors and a U-shaped piece attached on the top of inner root of ventral central anchors;the middle of dorsal connective plate is protruded downward,ventral connective plate with 2 ear-shaped raised;the copulatory （0.018～0.024 mm） is obvious shorter than that of the copulatory （0.045～0.058 mm） of N.gacilis and the copulatory （0.030～0.031 mm） of N.nagibinae.The supporting apparatus is wide laminated,extended from the base to 1/2～2/3 of whole length of copulatory,while the supporting apparatus of N.gacilis is ＂C-shaped＂ in the terminal.The supporting apparatus of N.nagibinae is not easy to be observed.
