Phylogenetic tree showing the position of Rhipicephalus bursa and Hyalomma marginatum marginatum compared to other tick species. The evolutionary history was inferred by using the maximum likelihood method based on the Hasegawa-Kishino-Yano model. A discrete Gamma distribution was used to model evolutionary rate differences among sites [4 categories (+G, parameter = 0.2936)]. The analysis involved 39 nucleotide sequences. All positions containing gaps and missing data were eliminated. There was a total of 267 positions in the final dataset. The scale-bar represents a 5% nucleotide sequence divergence
