Maximum-likelihood phylogeny based on the concatenated alignments of 32 single copy orthologs (4,365 amino acid sites) from Wolbachia using a partitioned best-fit model for each ortholog. Letters represent the major clades or supergroups; wPaga (in green type) constitutes new supergroup X and is distinct from the symbionts of Tyrophagus putrescentiae (wTput) and Syringophilopsis turdi (wStur) (in orange type)
