Presumed phylogeny of three Stegodyphus study species. Two species, S. dumicola and S. africanus, indicated with dashed branches, were added based on Johannesen et al (2007) to illustrate that the branches to S. tentoriicola and S. mimosarum do not represent single species only. Red branch bounds indicate social species. The splitting of the terminal branches in the species studied here represents the level of polymorphism within these three species. Split time estimates, substitution rate estimates (dN, dS and ω) and polymorphism estimates (π) were mapped on the phylogeny. The root was placed under the assumption of a molecular clock.
