Oral transmission from the consumption of processed food with triatomines and/or their feces infected with Trypanosoma cruzi prevails among recent cases of Chagas disease in Brazil. In Paraíba, a state of the Brazilian northeast, there was an outbreak caused by the consumption of sugarcane juice that resulted in 26 cases of infection and one death. Until now, 10 species of triatomines have been reported in this Brazilian state. Thus, we developed a dichotomous key to assist in the correct identification of Paraíba triatomines based on cytogenetic data. The dichotomous key allowed the differentiation of all the species in this state. Although the purpose of CytoKeys is not to replace dichotomous keys based on morphological data, the use of these complementary keys can help to solve taxonomic problems, preventing identification errors, especially between similar species such as Triatoma brasiliensis and Triatoma petrocchiae, both present in the Brazilian northeast.
经口摄入含有感染有克氏锥虫的美洲蜚蠊（Triatomine）及其粪便的加工食品是巴西近期出现的恰加斯病（Chagas disease）的主要传播途径之一。在巴西东北部的帕拉伊巴州（Paraíba），曾发生过一起因饮用甘蔗汁而引发的疫情，导致 26 人感染，1 人死亡。到目前为止，该州已报告了 10 种美洲蜚蠊。因此，我们根据细胞遗传学数据开发了一个二项式关键方法，以帮助正确识别帕拉伊巴州的美洲蜚蠊。该二项式关键方法能够区分该州的所有物种。虽然 CytoKeys 的目的不是取代基于形态数据的二项式关键方法，但使用这些互补的关键方法可以帮助解决分类学问题，防止鉴定错误，特别是在巴西东北部同时存在的巴西蜚蠊（Triatoma brasiliensis）和 Petrochelidon petrocchiae 等相似物种之间。
