Maximum likelihood (ML) tree based on the concatenated sequences of the control region (CR), ND4, ND5 and cyt b. The best-scoring ML trees from partitioned ML analysis based on a 4669 bp concatenated sequence of the four mtDNA regions. Numbers above the internal branches indicate neighbour-joining and ML bootstrap (BS) values and Bayesian (BI) posterior probabilities. The BS and BI values are given only for the nodes of the major clades. Haplotype numbers of concatenated sequences are followed by ploidy [2n, diploid; 3n, triploid (shaded); nd, ploidy not determined], corresponding CR haplotype numbers, and locality numbers. See Figure 6 for locality names. Roman numerals on the right side of the tree denote clade code numbers.
