Triatomines, also known as kissing bugs, are bloodfeeding insects in the subfamily Triatominae. They are important natural vectors of Trypanosoma cruzi, the parasite that causes Chagas disease (Lent and Wygodzinsky 1979). A total of 151 species has been described in the world and assigned to fifteen genera (Justi and Galvão 2017). In Mexico, there are 32 triatomine species grouped into eight genera. Triatoma is the most abundant (19 species), followed by Meccus (6), Belminus (1), Dipetalogaster (1), Eratyrus (1), Paratriatoma (1), Panstrongylus (2), and Rhodnius (1) (Galvão et al. 2003, Schofield andGalvão 2009). Most of these species have been found naturally infected with T. cruzi (Ramsey et al. 2015).The State of Mexico is not considered a Chagas endemic area; however, researchers have reported the occurrence of two species of triatomines, Triatoma dimidiata and Meccus pallidipennis, which have been reported only in southern municipalities, and the authors reported the active transmission of T. cruzi, which is found in domestic reservoirs and in humans infected with the parasite (Estrada-Franco et al. 2006, Barbabosa-Pliego et al. 2011, Quijano-Hernandez, et al. 2012. A recent study showed the seroprevalence of T. cruzi to be 9.1% in populations of the Hueypoxtla and Tequixquiac municipalities (Estado de Mexico), suggesting the possible presence of the vector in the area (González-Guzmán et al. 2017).Triatoma barberi was described in 1939 by Usinger and is an endemic species of Mexico, where it has been reported in Colima,
