the ME analysis, 1 000 bootstrap replicates (Felsenstein 1985) were performed. Maximum Likelihood Analysis was done using RAxML (Stamatakis 2006), on the webserver (Stamatakis et al.2008) at http://phylobench.vital-it.ch/raxml-bb/index.php with the gamma model of rate heterogeneity in effect and maximum likelihood search. Five runs with 100 bootstrap replicates using the rapid bootstrapping algorithm implemented on the RAxML webservers (Stamatakis et al. 2008) were combined and a consensus tree was computed using MEGA for assessing bootstrap support.
