A molecular phylogeny of Pacific honeyeaters (Aves: Meliphagidae) reveals extensive paraphyly and an isolated Polynesian radiation
چکیده انگلیسی


- We investigated the phylogenetic placement of 14 species of Pacific honeyeaters.
- A Central Polynesian radiation was recovered.
- Current taxonomy of Meliphagidae is in conflict with the molecular phylogeny.
- Foulehaio carunculatus should be considered three species.
- Melidectes whitemanensis should be treated in the monotypic genus Vosea.

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.
