Fig. 7. Maximum likelihood phylogenetic tree based on Partial sequences of two mitochondrial genes and three nuclear genes. The series of three numbers (e.g. 100/94/1) at each of the main nodes represents the percentage of bootstrap support obtained by Maximum Likelihood (ML), the percentage of bootstrap support obtained by the Maximum Parsimony (MP) analysis and the posterior probability for that split obtained in Bayesian analysis (B),respectively (1000 bootstrap replicates). Dashes represent values <50% (ML, MP) or <0.5 (B).
