FIGURE 1. Maximum likelihood estimation of the phylogenetic relationships based on the mitochondrial COI barcode region (Kimura 2-parameter model, discrete Gamma distribution for rate differences with 5 categories +G parameter = 0.3241. Nucleotide positions with less than 95 % site coverage were eliminated resulting in 581 analysed positions. Numbers of major nodes indicate bootstrap values from 1000 pseudoreplicates from the ML, NJ and MP method. Except to outgroup, the tree is drawn to scale with branch lengths depicting number of substitutions per site. Solid black bar shows the delimitation result using the PTP approach (eleven groups), dashed line the result based on the mPTP model (two groups).
