摘要
笔者于1966-1988年在云南东部的南盘江水系采到一批金线鲃标本,其中有3个系科学上尚未记载的新种,现描述于后。模式标本保存在中国科学院水生生物研究所和本校。 1.大鳞金线鲃,新种Sinocyclocheilus macrolepis sp.nov.(图1)。正模标本编号866007,全长177mm,体长145mm。1986年6月4日采于本厂龙潭。副模标本5尾,全长87-218mm,体长71-185mm。编号为865014、867005、876005,

Diagnosis: The new species is distinguished from Sinocyclocheilus malacopterus Chu et Cui by its strong and hard last unbrached dorsal ray and small body. All the type specimens mentioned above are kept in the Museum of the Institute of Hydrobiology Academia Sinica, Wuhan Hupei province, ect.
