摘　　要：描记采于曲靖市郊一地下水出水口金线鱼巴属一新种 ,命名为曲靖金线鱼巴Sinocyclocheilusqujingen sis,sp.nov.。新种口须特长 ,与长须金线鱼巴S .longibarbatusWang(1 989)相近 ,但体鳞细小 ,隐于皮下 ,头长等于体高 ,两种间分子遗传距离 1 3 6% 。Sinocyclocheilus qujingensis Li Mao et Lu, sp. nov. (fig 1) Holotype,No 910808001, 114 mm SL, was collected from Wujiafen Longtan(103°58′N,105°31′E) Qujing County Yunnan,on Aug 8,1991. Paratypes 15 speicmens, No 910808002-910808016, 116-176 mm SL, were collected from the same locality as the holotype. D,iii,7;A,ii,5;P,i,16;V,i,8;C,16.Gill rakers 6-8,LS,70-79,Pharyngeal teeth 3 rows,2.3.4/4.3.2.Body depth in standard length 3 21-4 13(3 60),head length 3 33-3 82(3 60),length caudal peduncle 4 32-5 11(4 60),depth caudal peduncle 7 21-8 80(8 11).Snout in head 2 73-3 50(3 20),eye 5 12 6 80(6 12),interorbital 2 90-3 44(3 22).Depth of caudal peduncle 1 40-2 02(1 80)in its length. The new species is similar to S. longibarbatus Wang(1989),but differs from the latter in:(1)Scale minutes and hided in skin;(2)Depth of the body being equal to length of head ;(3)distance heredity of molecule 13 6%. The type specimens are all deposited in Reservoir Heilongtan Shilin ,Yunnan.
