FIGURE 2.

Rank-normalized phylogenies of the archaeal families that harbor isolates or MAGs from arthropod guts (A–E). Taxa with representatives from arthropod guts are highlighted in color; green shading indicates genera that are recognized also in GTDB, red shading indicates those that are expanded in the present study. Newly proposed genera are in bold; the corresponding type species are given. Provisional names in the GTDB taxonomy are in parentheses. The maximum-likelihood tree is based on an alignment of 53 marker genes and was normalized using relative evolutionary divergence (RED) values determined with PhyloRank. The number of genomes in the collapsed clades is indicated. For an expanded version of the original tree, including genome accession numbers, see Supplementary Figure 1.
