Figure 4.Bayesian inference of the phylogenetic tree on the concatenated sequence. Numbers above branches indicate posterior probability/bootstrap (of the Maximum Likelihood analysis) support values higher than 0.9/70 (shown as asterisks on terminal branches). Black rectangles show clades not recovered in both analyses (the alternative is shown with a dashed line). The cryptic species included in Hormogaster elisae are numbered from 1 to 5 (following Novo et al. 2010).
