Figure 2 - The Neighbour-Joining tree of the entire dataset based on COI barcodes. Terminal branches have been collapsed in order to save space, the total number of specimens is given in brackets and the area surface of the triangle represents the amount of variation. When a terminal branch contains two species, both names are provided as well as their respective number of specimens. If a branch contains more than two species only the number of species as well as the number of specimens are given. Bootstrap values above 50 (1000 replicates) are given at the nodes.
