Maximum likelihood (ML) tree based on three mitochondrial genes 12S rRNA, 16S rRNA, COII and two nuclear genes 28S rRNA, histone H3. The topologies yielded by Bayesian inference (BI) are almost identical with ML tree (see supplementary material Fig. S1). Branch labels provide bootstrap support (bs) of nodes in ML and posterior probability (pp) (%) of nodes in BI; (*) indicates the branch label of the corresponding analysis is 100 or 1.0, respectively; (-) means the node is absent for the given analysis.
