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, Triatoma rubrovaria, Triatoma oliveirai, Triatoma pintodiasi, Triatoma klugi, Triatoma carcavalloi, and Triatoma circummaculata (with the addition Triatoma limai, which is endemic to Argentina) form the T. rubrovaria subcomplex. The last species described and grouped into this subcomplex was T. pintodiasi Thus, this study characterized the genetic distance between T. pintodiasi and of the other members of the T. rubrovaria subcomplex to evaluate the specific status of T. pintodiasi The genetic distance observed between T. pintodiasi and the other species of the T. rubrovaria subcomplex was large, a finding which highlights the specific status of the species considered to be cryptic of T. circummaculata.
恰加斯病最常通过与锥蝽亚科昆虫的粪便接触传播给人类。在巴西，有65种锥蝽分布在该国的27个州。在南里奥格兰德州的物种中，红变锥蝽、奥利维拉锥蝽、平托迪亚斯锥蝽、克鲁吉锥蝽、卡尔卡瓦洛锥蝽和环斑锥蝽（此外还有原产于阿根廷的利迈锥蝽）构成了红变锥蝽亚复合体。最后被描述并归入该亚复合体的物种是平托迪亚斯锥蝽。因此，本研究对平托迪亚斯锥蝽与红变锥蝽亚复合体其他成员之间的遗传距离进行了表征，以评估平托迪亚斯锥蝽的物种地位。平托迪亚斯锥蝽与红变锥蝽亚复合体其他物种之间观察到的遗传距离很大，这一发现突出了该物种被认为是环斑锥蝽隐种的物种地位。
