Cercomela属包括9种适应干旱的陆生鸟类，主要分布在非洲大陆，其中一种出现在印度。利用线粒体遗传数据，我们重建Cercomela内的分子进化关系及其与其他密切相关属的关系。在我们的分析中包括24个人代表所有9个Cercomela物种和23个人代表17个21水芹物种。此外，我们还包括Myrmecocichla，Thamnolaea和Saxicola属的代表，Phoenicurus，Tarsiger和Monticola作为外群类群。我们的分析结果表明，Cercomela属是多系的物种在三个不同的分支。5种尾形线虫C. dubia，C. scotocerca、黑尾拟步行虫C. familiaris、C. melanura和C. fusca与水芹属的关系比与其余的Cercomela物种的关系更密切。水芹属与这五种尾形目属并系。西南非洲的三种Cercomela：C tractrac，C schlegelii和C. sinuota，形成自己独特的分支。Cercomela sordida（Pinarochroa sordida，Sundevall）应保留Pinarochroa sordida，因为该物种在遗传上与所有其他聊天属/种高度不同。根据我们的研究结果，我们提出了一些分类学建议。(C)2009 Elsevier Inc.

The genus Cercomela comprises nine arid-adapted terrestrial bird species distributed primarily across the African continent with one species occurring in India. Using mitochondrial genetic data, we reconstructed molecular evolutionary relationships within Cercomela and its relationship to other closely related genera. Included in our analysis were 24 individuals representing all nine Cercomela species and 23 individuals representing 17 of 21 Oenanthe species. In addition, we included representatives of the genera Myrmecocichla, Thamnolaea and Saxicola, with Phoenicurus, Tarsiger and Monticola as outgroup taxa. Results of our analyses suggest that the genus Cercomela is polyphyletic with species in three distinct clades. Five Cercomela species: C. dubia, C. scotocerca, C. familiaris, C. melanura and C. fusca are more closely affiliated with Oenanthe than with the remaining Cercomela species. Oenanthe is paraphyletic with regard to these five Cercomela species. The three southwest African Cercomela species; C tractrac, C schlegelii and C. sinuota, form their own distinct clade. Cercomela sordida (Pinarochroa sordida, Sundevall) should remain Pinarochroa sordida as this species is genetically highly distinct from all other chat genera/species. Based on our results, we make a number of taxonomic recommendations. (C) 2009 Elsevier Inc. All rights reserved.
