Reconstruction of the primary hypothesis regarding the evolutionary scenario of the femoralis-group. Letters on the Figure correspond to the clades labeled with the same letter in Figure 4. Yellow and red dots represent species originating after a vicariant event, while green and white dots indicate founder events (green signifies the ancestral distribution, while white dots represent newly colonized areas). Symbols on the nodes indicate the events of GEM method: black square, vicariance; white triangle, founder event.
