Interpretive Summary: Parasitic wasps are critical for healthy ecosystem function as regulators of terrestrial arthropod populations. This includes their use as biological control agents of invasive or pestiferous insects. Stable hypotheses of evolutionary relationships within this large group are critical for predicting behavior that impacts agriculture in the United States. This paper explores the use of novel genomic data for building a new family tree for the Eulophidae. Biological control workers, scientists, and APHIS cooperators worldwide will find this research product essential for their own work.

Technical Abstract: Eulophidae is a hyper-diverse family of chalcidoid wasps with 324 genera, about 5300 described species and probably thousands of others to be described. Until now, the absence of unequivocal morphological apomorphies and the low resolution provided by the handful of Sanger sequenced genes have hampered the reconstruction of phylogenetic relationships within the family. Here we tested the power of Ultra-Conserved Elements (UCEs) and their flanking regions to resolve relationships among 84 species of eulophids included in 63 genera representing all subfamilies and most tribes, plus 15 outgroups. Our analyses recover all tradit ional Eulophidae subfamilies and tribes with high support and globally agree with the traditional classification of the family. Our results confirm that Eulophinae + Tetrastichinae is the sister group of (Opheliminae + Entiinae) + Entedoninae. At the generic level, our analyses provide high support for intergeneric relationships for which morphology and Sanger markers previously failed to provide resolution. Our results also demonstrate that Trisecodes can be definitively removed from Eulophidae. This work opens new avenues towards a better understanding of the evolutionary history, biogeography and evolution of host-parasitoid associations in this hyper-diverse family of chalcidoid wasps.
