* As showed in Figure 1 and Figure 2, all the nodes in the phylogenetic tree were numbered and marked.
** Diverge time of each branch was estimated in BEAST software and listed accordingly. The geological time scale (era and period) were inferred from the estimated diverge time of each nodes.
*** Posterior probabilities (PP) of every node were inferred via BEAST. Four of them were lower than 95%: 1) node 11; 2) node 19; 3) node 20; and 4) node 21.
