Chagas disease is most frequently transmitted to humans through contact with feces of insects from the Triatominae subfamily. In Brazil, there are 65 species of triatomines distributed throughout the country's 27 states. Among the species in the state of Rio Grande do Sul, , , , , , and (with the addition , which is endemic to Argentina) form the subcomplex. The last species described and grouped into this subcomplex was . Thus, this study characterized the genetic distance between and of the other members of the subcomplex to evaluate the specific status of . The genetic distance observed between and the other species of the subcomplex was large, a finding which highlights the specific status of the species considered to be cryptic of .
