利用线粒体12S、16S和COI基因的DNA序列比较，推断了8种锥口线虫[7]之间的系统发育关系。circummaculata（Stal），a member of a different complex based on morphology]. T. infestans（Klug）和T. Platensis Neiva的线粒体DNA的渗入。进化树的构建使用Panstrongulus Megistus（Burmeister）作为外群。这个外群给出了群的根在T. vitticeps（Stal）和其他物种。T. circummaculata进入infestans复合体的中间与形态学分类不一致，表明该类群目前的系统学分类没有反映系统发生的亲缘关系。
DNA sequence comparisons of 12S, 16S, and COI mitochondrial DNA (mtDNA) genes were used to infer phylogenetic relationships among 8 species of Triatoma [7 belonging to the infestans complex and T. circummaculata (Stal), a member of a different complex based on morphology]. There was remarkable mtDNA similarity between T. infestans (Klug) and T. platensis Neiva that can be explained by mtDNA introgression. Evolutionary trees were constructed using Panstrongulus megistus (Burmeister) as the outgroup. This outgroup gave evidence that the root of the group would be between T. vitticeps (Stal) and the rest of the species. The placement of T. circummaculata into the middle of the infestans complex is not consistent with the morphological classification, suggesting that the current systematics of this group does not reflect phylogenetic affinities.
