Divergence times estimation (based on species tree), S-DIVA and S-DEC analyses of the Pantosteus plebeius-nebuliferus species-group. Red labels represent the divergence times in millions years ago. The bold names represent the ancestral area estimated. Dispersal events and vicariant events are represented with - and | symbols, respectively. The * represent the value for posterior probability of 100% for each clade tested in the most sensitive species-delimitation model (four species) with values of Θ α=1, β=10; τ α=1, β=10 in the species delimitation analysis A10 and A11
