摘　　要：为编写中国动物志,对分布于云南的裂腹鱼类进行了全面整理,发现其中有五个以往文献中所没有记载过的新种和新亚种,现报道如下。少鳞裂腹鱼Schizothorax oligolepis,新种(图1)〔地方名〕冷水花全模标本21尾,1978年2月采自盈江县铜壁关。体长110—176毫米。背鳍条Ⅲ—7;臀鳍条Ⅱ—5;胸鳍条I—17—18;腹鳍条Ⅰ—9—10。侧线鳞第一鳃弓鳃耙,外侧13—14,内侧17—20。The present paper deals with the fishes of the genus Schizothorax Heckel collected from Central Yunnan in March 1960 and Western Yunnan in February 1978.Altogether five new species and subspecies are reported,they arc Schizothorax oligolepis oligolepis,S.oligolepis malacathus,S.dulongensis,S.clongatus and S,davidi fumingensis.The type specimens are preserved at the Kunming Institute of Zoology,Academia Sinica.Schizothorax oligolepis,sp.nov.(Fig.1)21 syntypes collected from Tongbiguan,Yingjiang Xian,Yunnan,in February 1978.Standard length 110-176 mm.D.Ⅲ-7;A.Ⅱ-5,P.Ⅰ-17-18,V.Ⅰ-9-10.L.1.8913(12-14)/11(10-12)v 93.Gill-raker external side 14(13-14),internal side 18(17-20).Pharygeal teeth 2.3.4-4.3.2.Vertebrae 4+40-41.Diagnoses:The new species is closely allied to Schizothorax moleswor-thi(Chaudhuri),but differs from it in the following Characters:lateral line scales8913(12-14)/11(10-12)v 93 vs.942322-24/17(17-18)v 99;gill-raker external 14(13-14)vs.17(16-17),internal side 18(17-20)vs.21(20-24).So it is closely alliedto Schizothorax molesworthi meridionalis Tsao,but differs from it in the following characters:thorax and venter with ascles vs.without scales;lateralline 89(13(12-14)/11(10-12)v 93 vs.100(31-37/27-33 v 112.Schizothorax oligolepis malacathus,subsp.nov.(Fig.2)11 syntypes collected from Xima,Yingjiang Xian,Yunnan,in February 1978.standard length 141-220 mm.D.Ⅲ-7;A.Ⅱ-5;P.Ⅰ-17-18l V.Ⅰ-9-10.L.1.87(19(18-21)/14(13-15)v 99.Gill-raker external side 13(11-14),its internal side 16(14-18).Pharygeal teeth 2.3.4-4.3.2.Vertebrae 4+41-43.Diagnoses:The new subspecies is closely allied to Schizothorax oligolepis oligolepis,but differs from it in the following characters:scales between lateral line and origin of the dorsal fin are 19(18-21)vs.13(12-14)scales between lateral line and brigin of the ventral fin are 14(13-15)vs.11(10-12).weak,smooth spine of the dorsal fin.Schithorax dulongensis,sp.nov.(Fig.3)5 syntypes collected from Bapo and Maku,Gongshan Xian,Yunnan,in May 1973.Standard length 99-189 mm.D.Ⅲ-8
