Statistical parsimony (95%) network of 60 cytb Campostoma ornatum haplotypes. Eight unconnected subnetworks were obtained (95%, connection limit = 14). Abbreviations correspond to the names shown in Table 1. River basins are in parentheses. Circle size reflects the frequency of each haplotype. Solid lines connecting each pair of haplotypes represent a single mutational event, regardless of their length. Small black rectangles represent missing or theoretical haplotypes. Roman numbers identify each subnetwork. Haplotype names are displayed beside each circle. Localities CAB and PRI (italics) contained individuals that clustered in two different subnetworks. Subnetwork VIII, shadowed in light green, was the most differentiated. The basal haplotype of each subnetwork is highlighted with a thicker circumference. Haplotypes RipFj9, SaaDq3 and CuaEu0 were retrieved from Genbank (accession numbers FJ913814, DQ324062 and EU082476, respectively).
