Weaverbirds are a diverse passerine group with species diversity concentrated in sub-Saharan Africa. No comprehensive phylogenetic hypothesis regarding relationships of weaverbirds has been produced, however, so we developed a first extensive phylogeny for the family Ploceidae, based on a multilocus dataset of three mitochondrial loci and four nuclear markers. Analysis of these data offered strong support for monophyly of the family and revealed seven distinct clades within Ploceidae. A major feature of our results is broad polyphyly of Ploceus: Asian Ploceus species should retain the generic name, whereas African Ploceus, together with Anaplectes, should be placed in Malimbus. In light of deep divergence, we assign the Malagasy Ploceus species to their own genus, Nelicurvius. Divergence time analysis based on DNA substitution rates suggests a mid-Miocene origin of the family. This study lays a foundation for an array of future studies of character evolution, biogeography, and evolutionary history of the family.
织布鸟是一个多样化的雀形目鸟类群体，其物种多样性集中在撒哈拉以南非洲地区。然而，目前尚未产生关于织布鸟亲缘关系的全面系统发育假说，因此我们基于三个线粒体基因座和四个核标记的多基因座数据集，为织布鸟科构建了首个广泛的系统发育树。对这些数据的分析为该科的单系性提供了有力支持，并揭示了织布鸟科内的七个不同分支。我们研究结果的一个主要特征是织雀属的广泛并系性：亚洲织雀物种应保留该属名，而非洲织雀与安纳织雀属应归入马利布雀属。鉴于分化程度较深，我们将马达加斯加织雀物种归入它们自己的属——内利弯嘴雀属。基于DNA替代率的分化时间分析表明，该科起源于中新世中期。这项研究为该科未来一系列关于性状进化、生物地理学和进化历史的研究奠定了基础。
