![]() Sociedade Brasileira de Zoologia: Curitiba, Brazil, 2014 289p. Vetores da Doença de Chagas no Brasil, 1st ed. Epidemiological profile of acute Chagas disease in individuals infected by oral transmission in northern Brazil. Investigação de surto de doença de Chagas aguda na região extra-amazônica, Rio Grande do Norte, Brasil, 2016. A checklist of the current valid species of the subfamily Triatominae Jeannel, 1919 (Hemiptera, Reduviidae) and their geographical distribution, with nomenclatural and taxonomic notes. Do the new triatomine species pose new challenges or strategies for monitoring Chagas disease? An overview from 1979-2021. Panstrongylus noireaui, a remarkable new species of Triatominae (Hemiptera, Reduviidae) from Bolivia. Triatoma guazu Lent and Wygodzinsky is a junior synonym of Triatoma williami Galvão, Souza and Lima. Trends in taxonomy of Chagas disease vectors (Hemiptera, Reduviidae, Triatominae): From Linnaean to integrative taxonomy. The risk of oral transmission in an area of a Chagas disease outbreak in the Brazilian northeast evaluated through entomological, socioeconomic and schooling indicators. Pesquisas prioritárias sobre doença de Chagas na Amazônia: Agenda de curto-médio prazo. Global, Regional, and National Trends of Chagas Disease from 1990 to 2019: Comprehensive Analysis of the Global Burden of Disease Study. The challenge of Chagas’ disease: Has the human pathogen, Trypanosoma cruzi, learned how to modulate signaling events to subvert host cells? N. Available online: (accessed on 4 December 2022). Drugs for Neglected Diseases Iniciative.Centers for Disease Control and Prevention.Available online: (american-trypanosomiasis) (accessed on 4 December 2022). The authors declare no conflict of interest. These subtle differences can result in taxonomic errors in entomoepidemiological surveys, emphasizing the importance of the taxonomic keys for correct species identification. membrane of hemelytra with a dark cloudy spot across the vein separating the two cells in T. presence of a practically glabrous rostrum and shorter first antennal segment in T. absence of a spongy pit in the tibiae of T. presence of light stains on the femurs of T. They exhibit morphological similarities and can be distinguished by the following characters: i. These species live in sympatry on rocky outcrops (where infection with T. petrocchiae has not been associated with major outbreaks to date, as it is rarely found in habitats related to the peridomicile or intradomicile. Triatoma brasiliensis is the most important vector of CD in semi-arid Brazil (frequently colonizing domiciles), and T. brasiliensis subcomplex reported in both states ( Table 1 and Table 2). petrocchiae (Pinto & Barreto, 1925) belong to the T. These alternative keys are expected to provide a useful tool for the scientific community and, above all, health agents, aimed at preventing mistakes from occurring in the identification of the vectors present in PE and RN related to CD outbreaks caused by oral infection. ![]() pseudomaculata has been misidentified as T. petrocchiae (present in both states) and T. All triatomine species could be distinguished by cytogenetic characteristics, emphasizing the importance of the newly developed taxonomic keys for the correct identification of triatomes from PE and RN, particularly for species that exhibit morphological similarities, such as Triatoma brasilensis and T. Considering the recent outbreaks of oral CD involving at least 27 cases of acute CD in Pernambuco (PE) as well as 18 cases and 2 deaths in the Rio Grande do Norte (RN), we developed dichotomous keys for the identification of triatomine species in these Brazilian states based on cytogenetic data. Brazil has the highest number of estimated cases and the largest number of deaths due to CD. Chagas disease (CD) affects about eight million people worldwide.
