Bayesian tree resulting from the phylogenetic analysis of the combined dataset according the best-fit partitioning strategy. Robustness of nodes was indicated by the clade posterior probability values (cpp in %). Boxes are drawn to gather species belonging to a group supported by a cpp-value higher than 90%. Green, orange, purple and blue boxes outlining the four supported groups in this study, i.e. Obsoletus, Imicola, Grahamii and Boophagus, respectively. For each species, the number of specimens used in the analysis is provided in parentheses and their country origin is referred using the ISO-3 country code
