Fifty-percent majority-rule consensus tree showing the clustering of the MOTUs obtained by the four MOTU delimitation algorithms. (The values at the node represent support values in the NJ/ML/BI analysis.) (NJ bootstrap support values below 0.50, ML bootstrap support values below 50 and Bayesian posterior probabilities below 0.50 are not shown.) The length of clade indicates the percentage of divergence. The ruler at the bottom represents a 0.02 replacement for each site. The branch colours match those in the right coloured segmented bar, whose coloured segments represent morphological species. The four black segments bar on the left relative to the species delimitation methods delineate the entities detected by each method. The finer black segments bar on the far right represents the division of the main clades
