Two parsimony haplotype networks representing the genetic relationship between Serranus papilionaceus (Canary Islands) and Serranus scriba (Malta) for the COI and ND2 data (The haplotype frequencies are proportional with the area of the circle. The numbers in the brackets represent the number of interspecific substitutions, while the black circles represent inferred putative haplotypes within species that were not observed during this study).
