摘　　要：云南路南县黑龙潭水库灌区的鱼类共有４８种；扣除外来种１２种，实有土著鱼种３６种，隶属于４目７科２８属。本文描记了新种大斑云南鳅ＹｕｎｎａｎｉｌｕｓｍａｃｒｏｓｉｔａｎｕｓＬｉ，ｓｐ．ｎｏｖ和叉尾云南鳅ＹｕｎｎａｎｉｌｕｓｆｏｒｋｉｃａｕｄａｌｉｓＬｉ．ｓｐ．ｎｏｖ，并对黑龙潭水库灌区的鱼类区系和动物地理学特征作了简要分析。Fish resources in the Heilongtan Reservoir and its drainage have been investigaed by the authors since 1965 and 48 species recorded in which 36 including 7 new species are local ones belonging to 28 genera,7 families and 4 orders.Among 7 new species,5 i.e. Sinocyclocheilus macrocephalus Li, S.oxycephalus Li, S.lunanensis Li, Noemacheilus lunanensis Li et Xia, Anabarilius goldenlius Li et Chen have been recorded previously.In the paper,the other two i.e. Yunnanilus macrositanus Li.sp.nov.and Yunnanilus forkicaudalis Li.sp.nov.are described.In addition,the fish fauna and the biogeography are analysed too. The two new species are described as follows: 1 Yunnanilus macroistanus Li.sp.nov(Fig.1) Holotype:No.6502041.Body length 49mm,collected from Heilongtan(24°45′42″N,103°15′29″E),Lunan,Yunnan in September 1965.Paratype:1 specimen,No.6502042.Body length 52mm,collected from the same locality as the holotype. D.iii-7;A.ii-5;P.i-11;V.i-8;C.i-16-17-i.Gill-rakes 8 Body depth in standard body length 4.7-4.9,head length 4.0-4.5,length of caudal peduncle 7.0-7.4,depth of caudal peduncle 8.8-10.4;Snout in head length 2.2-2.6,eye 5.5-6.5,interobital width 2.8-3.3.Depth of caudal peduncle 1.4 in its length. The new species is distinguished from Yunnanilus beipanjingensis Li.Mao et Sun(1994)by its side body 8-10 both large and circular black spack. 2.Yunnanilus forkicaudalis Li.sp,nov(Fig.2) Holotype:No.6509047.Body length 68mm,collected from Heilongtan,Lunan,Yunnan in September 1965,Paratype:5 specimens,No.6509046,6509048-49.Body length 36-62mm,collected from the same locality as the holotype.The other 2 specimens No.940901-02.Body length 54-84mm,collected from Niujie Township(24°′05N,104°02′E),Luoping,Yunnan in September 1994. D.iii-7;A.ii-5;P.i-9～11;V.i-8;C.i-16-i.Gill-rakes 12 Body depth in standard body length 4.6-5.2(4.9),head length 3.8-4.5(4.0),length of caudal peduncle 6.2-9.0(7.7),depth of caudal peduncle 10.0-12.0(10.9);Snout in head length 2.3-2.7(2.
