在过去的二十年里，我们对亚洲鸟类的系统学和分类学的了解有了很大的提高，由于采用综合分类方法进行了深入的研究，公认的物种数量显着增加。中国-喜马拉雅山区雀形目鸟类具有较高的多样性。目前在该区域内被视为多型物种亚种的几个异域或近地域分类群可能应该获得完整的物种地位，因此需要重新审视它们的分类地位。基于多位点数据、发声和形态分析，我们建议将白尾红喉丽金龟视为两个种，即喜马拉雅红喉丽金龟C. pectoralisensustricto和中国红喉C.位于中国西南部和中北部山区的茨拜威。根据我们基于线粒体基因座的年代分析，这两个物种在大约220万年前分道扬镳。我们进一步发现C. tschebaiewi与C.核数据中严格意义上的胸大肌，这表明了有丝分裂核不一致的状态，值得进一步研究。我们的研究结果表明，更新世的地理变化和冰川旋回可能导致了C。胸大肌复合体我们的研究强调了应用综合分类学方法充分揭示中国-喜马拉雅山脉真实鸟类多样性的重要性。
Our knowledge of the systematics and taxonomy of Asian birds has improved much in the last two decades, and the number of recognised species has increased significantly as a result of in-depth studies using an integrative taxonomic approach. The Sino-Himalayan mountains harbor a high level of passerine diversity. Several allopatric or parapatric taxa that are currently treated as subspecies of polytypic species within that region are likely to deserve full species status, and thus their taxonomic status needs to be revisited. Based on analyses of multilocus data, vocalizations and morphology, we propose that the white-tailed rubythroat Calliope pectoralis should be treated as two species, the Himalayan rubythroat C. pectoralis sensu stricto in the Tian Shan and Himalayan mountains, and the Chinese rubythroat C. tschebaiewi in the mountains of southwestern and north-central China. According to our dating analyses based on mitochondrial loci, these two species diverged approximately 2.2 million yr ago. We further found that C. tschebaiewi was paraphyletic to C. pectoralis sensu stricto in nuclear data, which demonstrates a state of mitonuclear discordance that warrants further work. Our results suggest that geographic changes and glacial cycles in the Pleistocene may have caused allopatric divergence in the C. pectoralis complex. Our study stresses the importance of applying an integrative taxonomy approach to fully unravel the true avian diversity in the Sino-Himalayan Mountains.
