Likelihood tree topologies, branch lengths and ancestral state reconstructions for the seven well supported lineages within Afrotropical Baetidae (a--g corresponding to clades A--G in figure 1), taken from the maximum likelihood tree. Branch thickness and letters corresponding to nodes are as in figure 1. Ancestral state likelihoods are shown for Africa (above branch leading to node if interest) and Madagascar (below branch). Significantly higher likelihood is marked by asterisk.
