中文摘要	2003年4月,于怒江二级支流镇康县境内的大叉河中采获一批墨头鱼属(Garra)鱼类标本,经鉴定为一新种,命名为怒江墨头鱼(G.nujiangensis Chen and Yang,sp.nov.).该新种主要鉴别特征:围尾柄鳞12～14:侧线鳞48～50:在小个体中有一对微小的吻须;背鳍分支鳍条8～9;侧线上鳞5～6,侧线下鳞3～4;体高小于头长;臀鳍起点处的小于眼后至吻端的距离;腹鳍前长为体长的50.0%～53.7%;肛门前长为体长的58.9%～63.9%:体宽为体长的16.7%～19.6%:体高为体长的19.2%～22.6%.本研究证实,在缺须的墨头鱼属的一些物种中,如高体墨头鱼(G.alticorpora)和怒江墨头鱼(G.nujiangensis),其幼体中往往具有一对很小的吻须.
英文摘要	A new species of the subfamily Labeoninae, Garra nujiangensis Chen and Yang, sp. nov. is recognized from a secondary branch of Nujiang River (upper Salween) in Zhenkang county, Yunnan province, China. It can be distinguished from other beardless Garra species by the following combination of characters: 12 − 14 circumpeduncle scales; 48 − 50 lateral- line scales; a pair of rudimentary rostral barbels present in little individuals; 8 − 9 branched dorsal-fin rays; 5 − 6 scales between dorsal-fin origin and lateral line and 3 − 4 scales between pelvic-fin origin and lateral line; caudal peduncle relatively stouter; length between snout tip to posterior margin of eye longer than body depth at anal fin origin; head length longer than body depth at dorsal fin origin; prepelvic length 50.0% − 53.7% of standard length; pre-anus length 58.9% − 63.9% of standard length; body width 16.7% − 19.6% of standard length; body depth at dorsal fin 19.2% − 22.6% of standard length. The present study also verified that the presence of tiny barbells is a juvenile character in some beardless Garra species, such as G. nujiangensis and G. alticorpora.
