Timema species phylogeny. Phylogeny redrawn from Riesch et al. [20] with the seven asexual lineages added from Schwander et al. [19] (in blue). The used sexual species are labelled in red. Pair numbers correspond to the most recent (i.e. pair 1) to the most ancient (i.e. pair 5) transition to asexuality (ranking from Bast et al. [21]).
