Three possible relationships between the Euura, Pristiphora, and Nematus clades. All are consistent with treatment of these three clades as separate genera, or combining all of them as a single genus Nematus. Including Euura, but not Pristiphora, within Nematus is consistent only with the tree shown in the middle (supported by previous analyses: Nyman et al. 2006; 2010).
