摘　　要：The phylogeny of the monal pheasants (Lophophorus) and their relationships to some species of the genera Tragopan,Pucrasia and Ithaginis were studied by comparing mitochondrial cytochrome b (cyt b) nucleotide sequences.The molecular phylogenetic trees show that:①the genus Tragopan and the genus Pucrasia share a common ancestor which is the sister taxon of the ancestor of the genus Lophophorus;②the genus Lophophorus had evolved into two branches:One was the Sclaters Monal;the other included the Chinese Monal and the Himalayan Monal.Considering its molecular phylogeny,distribution patterns and morphological evidences,the genus Lophophorus might originate in the Hengduan mountains region of southwestern China.通过雉科虹雉属 (Lophophorus)、角雉属 (Tragopan)、勺鸡属 (Pucrasia)和血雉属 (Ithaginis) 7种鸟类的细胞色素b (cytb)基因序列比较 ,构建的虹雉属及其近缘属的分子系统树表明 :① 3种虹雉构成一个单系群 (monophyleticgroup) ,虹雉属与角雉属、勺鸡属构成一个单系群 ;②虹雉属内分为白尾梢虹雉 ,以及棕尾虹雉和绿尾虹雉两个演化枝。综合分子系统学、地理分布格局和形态学的证据 ,推测虹雉属鸟类起源于中国的横断山脉 ,其中繁衍生活在原地的一枝演化为白尾梢虹雉 ;另一枝则分别进入喜马拉雅山区 (西 )和中国西南部 (东 ) ,向西的演化为棕尾虹雉 ,向东的则为绿尾虹雉。
