Figure 2. Histogram showing the distribution of pairwise genetic distances within the data, obtained using ABGD. The unique, large and obvious barcode gap between 5 and 14% is used here as an objective separation between intraspecific (<5%) and interspecific (> 14%) divergences. There is a continuum within both intraspecific and interspecific divergences (i.e. no additional gap can be detected within intraspecific or interspecific divergences, even though there is a peak of intraspecific divergences <1% and a peak of interspecific divergences between 16 and 17%.
