A new species of Hemigrammus is described from the upper Rio Negro, Amazon basin, Brazil. The new species is distinguished from all congeners by its unique color pattern consisting of a single humeral blotch clearly spaced from a conspicuous midlateral dark stripe, which extends from fifth or sixth anteriormost vertical scale row to the basis of the middle caudal-fin rays. Comments on its putative relationships are provided.
一种新的半线脂鲤属物种在巴西亚马逊河流域的上里奥内格罗被描述。该新物种与所有同属物种的区别在于其独特的颜色模式，即由一个明显与一条显著的体侧中暗条纹隔开的单一肩部斑点组成，该暗条纹从最前面的第五或第六垂直鳞片行延伸至尾鳍中部鳍条基部。文中还对其可能的亲缘关系进行了评论。
