摘　　要：截至1985年止,我国共记载被认为有效的纹胸(鱼兆)属鱼类18种(亚种)。通过对采自全国各地的4000余尾标本的整理,18种中仅14种真正有效。加上本文描述的2个新种,报道的3个新纪录,我国共有纹胸(鱼兆)属鱼类19种(亚种)。纹胸(鱼兆)属鱼类的皮肤表面突起分化明显,该性状在种内稳定,可以分为6种类型。某些骨骼的分化,如复合椎体、髓棘、胸带、背骨等,也很有分类价值。本文以皮肤突起类型及骨骼特征为主,辅以一些稳定可靠的体色型、腹鳍的相对位置等,对19种做了分类检索表。There were 18 species of the genus Glyptothorax recorded from China and considered to be valid by previous authors before 1985.Having done through revision on the basis of more than four thousand specimens collected throughout China,the authors believe that only 14 species are actually valid.G.longinema Li and G.rubermentus Li are nothing rather than synonyms of the valid species G.zainaensis Wu et al.(1981),G.trilineatoides Li and G.fukiensis punctatum(Nichols)are synonymized into G.trilineatus Blyth and G.fukiensis fukiensis(Rendahl)respectively.The surface projections of skin in this genus which are stable within each species and of diagnostic significance can be distinguished into six patterns(Fig.1).The differentiation of some skeletons,such as vertebrae complex,neural spines of vertebrae,pectoral girdle,basal bone of the dorsal fin,is also significant in classification.Besides,the colour patterns of the body,relative position of ventral fin etc.are convenient,reliable diagnostic characters as well.On the basis of these characters a provisional key to 19 species in China is presented.Two new species are described.They are diagnosed as follows.Glyptothorax longjiangensis,sp.nov.(Fig.5)Holotype No.764246,117 mm SL,Longjiang river(upper tributary of Irrawaddy river),Tengchong county(25°00’N,98°30’E),Yunnan,April 1976.Paratype No.764241,90 mm SL,same data.D.Ⅱ,6;P.Ⅰ,11Ⅴ.i,5;A.ii-iii,10.Gill rakers 8-9.The new species is similar to G.minimaculatus Li.It can be distinguished from the later by its skin on the dorsal surface of head covered with ridged plaques(Fig.1-D)vs.granulated plaques in the later(Fig.1-A),by the skin on body densely granulated(Fig.1-E)vs.ridged plaques in the later,by the pectoral fins longer than the head and by the spine weaker than that of G.minimaculatus.Glyptothorax deqinensis,sp.nov.(Fig.6)Holotype No.748621,109mm SL,Deqin county(28°30’N,99°00’E),Yunnan,Aug.1974.Paratypes 32 specimens,47-132 mm SL,from Deqin and Weixi(27°20’N,99°10’E)counties,upper part of Lancangj
