A concatenated phylogenetic tree, based on the five multilocus sequence typing (MLST) genes (gatB, coxA, hcpA, fbpA, and ftsZ) combined into a 1988 bp contig. The tree includes contigs of Wolbachia strains from different hosts (indicated by drawings) and supergroups (capital letters; more details in the Supplementary Table S2). The Wolbachia strains of Synosternus cleopatrae fleas described in this study, are marked in bold.
