Morphological phylogram of specimens of Sternalixodes from Argentina, Australia, New Zealand and Uruguay. The relationships were inferred based on 38 morphological characters using Maximum Parsimony (MP) and Bayesian Inference (BI) methods. Ixodes tasmani was used as the outgroup. There was a concordance in the topology between this MP tree and that produced using BI (not shown). Nodal support (from left to right) is given as a posterior probability for BI and bootstrap values for MP. For simplicity, each clade number includes taxa in the preceding clade. The scale-bar indicates the number of inferred substitutions per character
