FIGURE 3. Best scoring maximum likelihood tree recovered from the analysis of the COI alignment (lnL = -100106.195003). Likelihood bootstrap support values and parsimony bootstrap support values are denoted above and below each node, respectively. Branches are drawn proportionate to the amount of change and GenBank accession numbers are noted before each taxon. Taxon names on tip labels of GenBank sequences are based on identifications made by previous studies. The neotype specimen of H. stagnalis is indicated in bold. Dagger (†) indicates non-scute-bearing specimens.
