Wheatears of the genus Oenanthe are birds specialized to desert ecosystems in the Palaearctic region from Morocco to China. Although they have been the subject of many morphological and ecological studies, no molecular data have been used to elucidate their phylogenetic relationships, and, their relationships are still debated. Here we use DNA sequences of 1180 bp of two mitochondrial genes, 16S rRNA and cytochrome oxidase subunit I, from 32 individuals from Middle East and North Africa, and Bayesian methods to derive a phylogeny for 11 species of Oenanthe. The resulting tree supported three major clades: (A) O. alboniger, O. chrysopygia, O. lugens, O. finschii, O. leucopyga, O. picata, O. moesta, (B) O. deserti and O. pleschanka; and (C) O. isabellina and O. oenanthe. These results largely differ from previous hypotheses based on analysis of morphological and chromatic characters. However, the two clades (B) and (C) were also supported by a phenetic analysis of new morphometric data presented here, indicating that characters related to colouration and ecology in Oenanthe are more strongly influenced by homoplasy than those of body shape.
穗鵖属（Oenanthe）的穗鵖是适应从摩洛哥到中国的古北界沙漠生态系统的鸟类。尽管它们一直是许多形态学和生态学研究的对象，但尚未使用分子数据来阐明它们的系统发育关系，并且它们之间的关系仍存在争议。在这里，我们使用来自中东和北非32个个体的两个线粒体基因（16S rRNA和细胞色素氧化酶亚基I）的1180 bp DNA序列，并采用贝叶斯方法推导了11种穗鵖的系统发育。所得的树支持三个主要分支：（A）黑头穗鵖、金胸穗鵖、褐背穗鵖、芬氏穗鵖、白腰穗鵖、纯色穗鵖、漠穗鵖；（B）漠穗鵖和白斑黑石鵖；以及（C）沙白喉林莺和穗鵖。这些结果与先前基于形态和颜色特征分析的假设在很大程度上不同。然而，这里呈现的新形态测量数据的表型分析也支持了分支（B）和（C），这表明穗鵖属中与颜色和生态相关的特征比体型特征更容易受到同塑性的影响。
