Localities for each specimen are provided in Appendix I. (a). Strict Consensus tree of six equally most parsimonious trees (length of 330 steps). Numbers above branches represent Maximum Parsimony and Minimum Evolution bootstrap proportions (each based on 1000 pseudoreplicates); numbers below branches represent decay indices. (b). Maximum Likelihood tree (InL = 2418.09) obtained using the GTR+I model of nucleotide substitution. Numbers above branches indicate bootstrap proportions (based on 100 pseudoreplicates).
