Note.—BS was assessed with RAxML from 1,000 bootstrap replicates (see Materials and Method). BS printed in brackets was assessed from partitioned ML analyses of data sets M_Ento, and its subsets using the Ufboot algorithm of IQ-TREE with 5,000 bootstrap replicates (supplementary material [section 5], Supplementary Material online). M_Ento is the decisive data set in which all OGs are covered by Protura, Diplura, and Collembola; SOS, SOSω, and the data sets from Meusemann et al. (2010; data set SOS, ML tree) and von Reumont et al. (2012; data set SOS, ML tree Set 1red) are indecisive to address the relationships of entognathous hexapod orders. M_Nono, M_Elli, and M_DiCo are subsets of M_Ento with predominant signal for different topologies and point out conflict of signal among genes.
aDiplurans are paraphyletic: Campodea + (Acerentomon,Megajapyx).
