摘要
描记1965年10月采于云南省路南县(现石林县)巴江的鲤属鱼类一新种,命名巴江鲤cyprinus(cyprinus)bajiangensis Li sp.nov.,当年曾误记为云南鲤cyprinus(cyprinus)yunnanensis Tchang,现经检视标本,本种仅有一对口角须与云南鲤相似,但有下列明显特征可区别.(1)头型正常vs.尖长;(2)口端位,马蹄形vs.口亚上位,斜裂;(3)胸鳍条i-19~20vs.i-16;(4)头长为眼间距的2.50~2.63倍vs.3.4~4.2倍;(5)侧线上下鳞■;(6)体较高,体长为体高的3.00~3.04倍vs.3.5~4.0倍.
This paper describes a new species of the genus Cyprinus,Cyprinus(cyprinus)bajiangensis Li sp.nov.,which was collected from the Bajiang in Lunan County(now Shilin County)of Yunnan,China in October,1965.This new species was once mistaken for cyprinus(cyprinus)yunnanensis Tchang,1993.The new species is similar to C.yunnanensis in the pair of maxillary barbels but differs in the following features:①normal head(vs.pointed and long head);② U-shaped mouth in end position(vs.oblique-fissure mouth in sub-up position);③Pi.-19~20(vs.i-16);④head length in interorbital width 2.50~2.63(vs.3.4~4.2);⑤scales row above lateral line 5(vs.6~7),scales row below lateral line 4(vs.5~6);⑥body depth in standard length 3.00~3.04(vs.3.5~4.0).
