Members of the subfamily Triatominae, also named kissing bugs – due to their nocturnal feeding on the lips of sleeping humans – are of relevance for the transmission of the pathogenic agent of American trypanosomosis respectively Chagas disease, Trypanosoma cruzi.

Members of the heteropteran family Reduviidae are commonly called assassin bugs, because most species attack and feed on other insects. In the family Reduviidae there are 24 subfamilies, including the subfamily Triatominae (kissing bugs). This subfamily is currently divided into 5 tribes and 17 genera with at least 149 valid species. The term kissing bug is a colloquial term that refers to a variety of species in the Triatominae subfamily (triatomines) that commonly seek out uncovered host mucosal surfaces, and thus will frequently bite the face.
All triatomines have the potential to transmit the pathogenic agent of Chagas disease, Trypanosoma cruzi. Of the currently known approximately 140 triatomine species, about half have been shown to be vectors, and fewer than two dozens are considered vectors of major epidemiological importance (Jurberg et al., 2005; Stevens et al., 2015). Those species which are most important as vectors of T. cruzi, belong to the tribes Triatomini and Rhodniini (Vallejo et al., 2009).
