Phylogeny and generic classification of the Anthidiini bees from the Neotropical region (Hymenoptera: Apidae)
The results provide strong support for the monophyly of the tribe, despite a representation biased towards the Neotropical taxa, and may be useful for future phylogenetic studies involving the Anthidiini from other biogeographic regions.
