摘　　要：报道了分别寄生于花尾胡椒鲷Plectorhynchuscinctus(Temminck＆Schlegel)和蓑Pteriossp 鳃上的嗜石鲈虫属一新种和海盘虫属一新种。胡椒鲷嗜石鲈虫,新种Bravohollisiaplectorhynchus,sp nov 的中央大钩的形状与本属其它种相似,但交接器的形状和量度有明显差异;蓑海盘虫,新种Haliotremapterois,sp nov 的中央大钩的形状与马卡萨海盘虫Haliotremamacassarensis(Yam.,1963)Bychowsky＆Nagibina,1971相似,但量度略长;交接管均为弯曲的长管,但已知种的交接管长度比本种短1/3,且已知种交接管有多条几丁质丝环绕,几丁质丝末端伸离管壁,而该种只有1条几丁质丝环绕交接管,末端附在交接管上,该种还具有一倒"L"形的基座。One new sqecies of Bravohollisia Bychowsky & Nagibina,1970,parasiting in the gimls of Plectorhynchus cinctus(Temminck & Schlegel)was descriped.One new species of Haliotrema Johnston & Tiegs,1922, parasiting in the gills of Pterios sp. Bravohollisia plectorhynchus,sp.nov. is similar to other species of this genus in the shape of two pairs anchors,but differs in the structure and measurement of copulatory organ.
