Fig. 1: ‘BaSk’ is a clade of anaerobic protists that branches as sister to all known Fornicata within the Metamonada.

A–D Differential interference contrast light micrographs of skoliomonad lineages Skoliomonas litria (A), Skoliomonas sp. GEMRC (B), and Skoliomonas sp. RCL (C) (imaging and methods described in ref. 22), as well as Barthelona sp. PCE (D) showing overall morphology. Scale bars indicate a length of 10 µm. E A maximum likelihood (ML) phylogeny based on 174 concatenated aligned proteins encompassing 46,113 sites. The depicted topology was estimated using IQ-TREE under the LG + C60 + F + Γ model and was used as a guide tree for estimating the LG + PMSF(C60) + F + Γ model. Support under the latter model was evaluated by SH-aLRT support percentage, aBayes support and nonparametric bootstrap percentage based on 100 nonparametric bootstrap replicates. The scale bar indicates the expected number of amino acid substitutions per site under the PMSF model. When at least one support value was less than maximal, all three are shown on the branch in the order SH-aLRT support percentage/aBayes/nonparametric bootstrap percentage. A black dot on the branch indicates all three approaches yielded full (i.e. 100/1/100) support. The BaSk clade is highlighted in red. See Supplementary Fig. 1 for full phylogenomic tree.
