We investigated the molecular phylogenetic placement of 14 species of Pacific island honeyeaters (Aves: Meliphagidae) in the broader context of an existing family-level phylogeny. We examined the evolutionary history of Pacific honeyeater lineages to assess the accuracy of current taxonomies and to evaluate their biogeographic history. We compare these biogeographic patterns to other Pacific birds to identify emergent patterns across lineages. We found strong support for a previously unknown endemic radiation in central Polynesia, which comprises five genera: Meliarchus, Guadalcanaria, Gymnomyza, Xanthotis, and Foulehaio. Conversely, other Pacific lineages were found to be strongly allied with continental radiations (e.g., Philemon eichhorni, P. cockerelli, and Lichmera incana). Our results necessitated taxonomic changes, both at the generic level (e.g., Xanthotis, Melidectes/Vosea, and Glycifohia/Gliciphila) and regarding species limits within polytypic species. Here, we discuss species limits in Foulehaio and Gymnomyza and recommend elevating three nominal subspecies of Foulehaio to species status, each of which forms well-differentiated clades.
我们在现有的科级水平系统发育框架内，调查了太平洋岛屿吸蜜鸟（雀形目：吸蜜鸟科）14 个物种的分子系统发育位置。我们研究了太平洋吸蜜鸟谱系的进化历史，以评估当前分类学的准确性，并评估它们的生物地理历史。我们将这些生物地理模式与其他太平洋鸟类进行比较，以确定不同谱系之间出现的模式。我们发现，在中波利尼西亚存在一个以前未知的特有辐射，其中包括五个属：Meliarchus、Guadalcanaria、Gymnomyza、Xanthotis 和 Foulehaio。相反，其他太平洋谱系与大陆辐射密切相关（例如，Philemon eichhorni、P. cockerelli 和 Lichmera incana）。我们的结果需要进行分类学上的改变，包括在属级（例如，Xanthotis、Melidectes/Vosea 和 Glycifohia/Gliciphila）和多型种内的种限方面。在这里，我们讨论了 Foulehaio 和 Gymnomyza 中的种限问题，并建议将 Foulehaio 的三个名义亚种提升为种的地位，每个亚种都形成了分化良好的分支。
