Phylogenetic tree of Wolbachia based on six markers using maximum-likelihood inference. Analysis based on concatenation of 16S rDNA, ftsZ, dnaA, coxA, fbpA and gatB (3086 bp in total length). The topology was generated using model TIM + F + I + G4 with IQ-TREE. The robustness of nodes was assessed with 1000 bootstrap replicates. The Wolbachia supergroups (A–F, J and L) were identified according to Lefoulon et al. [28] and Lo et al. [43]. The scale-bar indicates the distance in substitutions per nucleotide. Abbreviation: wb, Wolbachia
