Phylogenetic reconstructions for each clade obtained from concatenated sequences for each dataset. a phylogenetic reconstruction from the 1552 orthologues in clade IV; b phylogenetic reconstruction from 1510 orthologues in clade V. Branches used for Likelihood Ratio Tests (LRTs) are marked according to the species lifestyles; ■, entomopathogenic; ●, vertebrate parasite; ♦ parasite branch; ▲, free-living. All tests were based on an unrooted phylogeny; the trees are rooted for display purposes only. Values correspond to branch lengths, and bootstrap values are shown under the branch leading to the animal parasites
