FIGURE 4 in DNA Barcoding of Pyrrhulina australis (Characiformes: Lebiasinidae) reveals unexpected cryptic diversity in the group

FIGURE 4 | Quadrant plot showing the maximum K2P intraspecific distances and the maximum K2P interspecific in percentages for the nominal Pyrrhulina species analyzed in the present study. The lines indicate the threshold (1.79%) between the intra- and interspecific distances. The morphology of the species in quadrant I is consistent with the molecular identification. The species in quadrant II probably have cryptic forms. Species present in quadrant III are likely the result of recent divergence, hybridization or synonimization, while quadrant IV represents a lack of correspondence between the morphological and molecular identifications.
