The phylogenetic position of Triatoma sherlocki within triatomines group was inferred by analyzing mtDNA fragments of Cyt B and 16S ribosomal RNA by using maximum parsimony and Bayesian analysis. Despite being differentiated from members of the T. brasiliensis complex on morphologic grounds, molecular phylogenetic analysis suggests T. sherlocki is a member of this complex; moreover, it was placed as a sister species of T. melanica. These suggestions were supported by robust credibility rates. Hence, we show evidence for the paraphyletic group of the "Triatoma brasiliensis complex," which should be composed of T. brasiliensis brasiliensis, T. brasiliensis macromelasoma, T. juazeirensis, T. melanica, and T. sherlocki.
通过使用最大简约法和贝叶斯分析，对克氏锥蝽（Triatoma sherlocki）细胞色素B（Cyt B）和16S核糖体RNA的线粒体DNA片段进行分析，推断出其在锥蝽类群中的系统发育位置。尽管基于形态学理由，克氏锥蝽与巴西锥蝽复合体（T. brasiliensis complex）的成员有所不同，但分子系统发育分析表明，克氏锥蝽是该复合体的成员；此外，它被定位为黑腹锥蝽（T. melanica）的姐妹种。这些推测得到了较高可信度的支持。因此，我们证明了“巴西锥蝽复合体”的并系群证据，该复合体应由巴西锥蝽指名亚种（T. brasiliensis brasiliensis）、巴西锥蝽大黑斑亚种（T. brasiliensis macromelasoma）、茹阿泽鲁锥蝽（T. juazeirensis）、黑腹锥蝽和克氏锥蝽组成。
