The triatomines vectors of are principal factors in acquiring Chagas disease. For this reason, increased knowledge of domestic transmission of and control of its insect vectors is necessary. To contribute to genetic knowledge of North America Triatominae species, we studied genetic variations and conducted phylogenetic analysis of different triatomines species of epidemiologic importance. Our analysis showed high genetic variations between different geographic populations of , , , , and species, suggested initial divergence, hybridation, or classifications problems. In contrast, , , and populations showed few genetics variations. Analysis using cytochrome B and internal transcribed spacer 2 gene sequences indicated that is closely related to the complex and not to . and showed a close relationship with and complexes.
