A new species D.G. Zhang & Q. Zhou (Asteraceae, Senecioneae) from Guizhou Province, China, is described and illustrated based on its morphological characteristics and molecular evidence. It closely resembles and , the former in the scapigerous habit and smooth and glabrous achene surface, the latter in the calyculate involucre and purple abaxial leaf surface, and both in the shape and indumentum of leaf lamina, but differs markedly from the latter two in having fewer capitula and epappose achenes. Phylogenetic analysis based on nrITS and sequences shows that this new species belongs to the clade and is sister to with moderate support.
基于形态特征和分子证据，描述并图示了中国贵州省菊科千里光族的一个新物种——张DG和周Q。它与[物种1]和[物种2]密切相似，前者具有花葶状习性且瘦果表面光滑无毛，后者具有具总苞状的总苞和叶片背面紫色，二者在叶片形状和毛被方面也相似，但该新物种与后两者明显不同，在于头状花序较少且瘦果无冠毛。基于nrITS和[序列名称]序列的系统发育分析表明，这个新物种属于[分支名称]分支，在适度支持下是[物种名称]的姐妹种。
