%X The palm family (Arecaceae) has a rich history of phylogenetic research, including several recent phylogenomic studies. However, densely sampled phylogenomic datasets for larger palm clades - such as subfamilies - are still few in number. We used target sequence capture to obtain data for 971 nuclear genes across 421 (ca. 80%) species in the subfamily Coryphoideae. We inferred a robust phylogenetic tree to address systematic issues in the subfamily, specifically the relationships among tribes Cryosophileae, Sabaleae, Phoeniceae and Trachycarpeae, the affinities of seven genera in Trachycarpeae that are not currently assigned to any subtribe, and the monophyly of genera across the subfamily. We recovered relationships among tribes that are in accordance with other major nuclear phylogenomic datasets, but that are incongruent with trees derived from plastome sequences. Importantly, the placement of tribe Phoeniceae (the date palms) remains contentious. Our tree recovered with high support the relationship of all unplaced Trachycarpeae genera, paving the way for an updated classification. Most genera were resolved as monophyletic except for Livistona and all three genera of tribe Caryoteae, calling for a revision of generic limits. Our tree clarifies the relationships of many fan palm species for the first time, allowing for future studies of diversification, trait evolution or biogeography.
