Figure 15. A in Description of six new species of Loxosceles (Araneae: Sicariidae) endemic to the Canary Islands and the utility of DNA barcoding for their fast and accurate identification
Figure 15. A, graphical representation of the barcode gap comparing the minimum interspecific Kimura two-parameter (K2P) distance to the maximum intraspecific K2P distance. Values above the 1:1 line indicate the presence of a 'barcode gap'. B, graphical representation of the identification error. False positives in blue and false negatives in red. The optimum threshold value is between 5.5 and 9.8% K2P distance, with an error of 0%.
