摘　　要：记述了寄生于黑鲷Sparus macrocephalus(Basilewsky)与紫红笛鲷Lutjanus argentimaculatus(Forskai)鳃上的海盘虫属一新种及寄生于勒氏笛鲷Lutjanus russelli(Bleek,1849)鳃上的螺管海盘虫Haliotrema spirotubiforum Zhang,2001,长阴宽海盘虫Euryhaliotrema chrysotaeniae(Young,1968)Kritsky&Boeger,2002。瘤钩海盘虫,新种Haliotrema tukerhamatus sp.nov.的两对中央大钩钩尖基部有一瘤状突起;背中央大钩和背联结片的形状均相似于Haliotrema longihamus Zhukov,1976,但新种背腹中央大钩形状相同,均没有内外突的分化;腹联结片前缘凹入,中部后缘有一显著的向后凸起,而已知种背腹中央大钩形状相异,腹中央大钩内外突分化明显,腹联结片平直;新种交接管近端多次弯曲,远端环绕一圈,而已知种交接管仅在中部环绕一圈。This paper descriped one a species of Haliotrema Johnston ＆ Tiegs, 1922, parasiting in the gills of Sparus macrocephalus （Basilewsky） and Lutjanus argentimaculatus （Forskai） and Haliotrema spirotubiforum Zhang, 2001 and Euryhaliotrema chrysotaeniae （Young, 1968）Kritsky ＆ Boeger, 2002. parasiting in the gills of Lutjanus russelli （Bleek, 1849）. Haliotrema tukerhamatus sp. nov. is similar to Haliotrema longihamus Zhukov, 1976 in the two pairs of central anchors which basal portion ,of hookpoint has a tumourlike raised and in the shape of dorsal central anchor and connective plate, but the shape of two pairs of central anchors similar to the new species, outer root not obvious,ventral connective plate arcuated backward with an obvious bulge in the middle, arid the shape of two pairs of central anchors dissimilar to the known species, the inner and outer roots of ventral central anchors well developed,and ventral connective plate lame.liar, relatively straight; Copulatory tube of the new species also differs from the known species.
