Fig. 3: deduced phylogenetic tree of nine Triatoma infestans populations, T. melanosoma and T. brasiliensis. Tree construction was based on DNA sequence data obtained from the mtCytb gene fragment of each species/population and analyzed by the Neighbor-Joining method. Bold numbers represent the bootstrap values supporting each clade. Vertical numbers are the shared derived characters (synapomorphies) that support each clade, or characterize each terminal lineage (autapomorphies). * Represents the fifty synapomorphies that support the T. infestans/T. melanosoma clade.
