我们利用DNA序列数据重建了变矮翠鸟（Ceyx lepidus）的地理关系。最大似然法和贝叶斯分析方法被用来重建树的多位点数据集的所有15个命名亚种的青鱼种复合体。连接的数据集长度为2，471个碱基对，包括两个线粒体基因和两个非编码核内含子。支持C.莱皮多斯模棱两可。相反，我们发现了一个包括所有C的分支的支持。lepidus亚种加上两个菲律宾特有分类群：C. argentatus和C.蓝鲸亚种分类群之间的关系没有得到很好的解决，许多节点被折叠成polytomies表明快速和广泛的殖民化。原地多样化可能发挥了作用，在四个群岛：菲律宾，马鲁古，俾斯麦和所罗门群岛内产生当前的多样性。一些在所罗门群岛的分类群中发现的地理模式与在其他鸟类中发现的模式相匹配，例如布干维尔、乔伊勒和伊莎贝尔上的分类群之间的密切关系。相比之下，瓜达尔卡纳尔岛和新格鲁吉亚群的种群之间的姐妹关系是新颖的。我们讨论了物种的限制，并提出分类建议，以对待所有15个亚种的C。lepidus作为物种。接收日期：2012年5月31日，接受日期：2012年11月5日。
We reconstructed the phylogeographic relationships of the Variable Dwarf-Kingfisher (Ceyx lepidus) using DNA sequence data. Maximum likelihood and Bayesian analysis methods were used to reconstruct trees from a multilocus data set of all 15 named subspecies of the Ceyx lepidus species complex. The concatenated data-set length was 2,471 base pairs and included two mitochondrial genes and two noncoding nuclear introns. Support for the monophyly of C. lepidus was equivocal. We instead found support for a clade including all C. lepidus subspecies plus two endemic Philippine taxa: C. argentatus and C. cyanopectus. Relationships among subspecific taxa were not well resolved, and many nodes were collapsed into polytomies suggesting a rapid and widespread colonization. In situ diversification likely played a role in generating current diversity within four archipelagos: the Philippines, Malukus, Bismarcks, and Solomons. Some biogeographic patterns recovered for the Solomon Islands taxa match those seen in other bird species, such as the close relationship of taxa on Bougainville, Choiseul, and Isabel. By contrast, the sister relationship between populations on Guadalcanal and the New Georgia Group is novel. We discuss species limits and make taxonomic recommendations to treat all 15 subspecies of C. lepidus as species. Received 31 May 2012, accepted 5 November 2012.
