Abstract
Chagas disease persists as one of the most important, and yet most neglected, diseases in the world, and several changes in
its epidemiological aspects have been recorded since its discovery. Currently, some of the most relevant changes are related to: (i)
the reduction in the incidence of the endemic due to the control of the most important vectors, Triatoma infestans and Rhodnius
prolixus, in many countries; (ii) the migration of human populations spreading cases of the disease throughout the world, from
endemic to non-endemic areas, transforming Chagas disease into a global threat; and (iii) new acute cases and deaths caused
by oral transmission, especially in the north of Brazil. Despite the reduction in the number of cases, new challenges need to be
responded to, including monitoring and control activities aiming to prevent house infestation by the secondary vectors from
occurring. In 1979, Lent & Wygodzinsky(1) published the most complete review of the subfamily Triatominae, encompassing 111
recognised species in the taxon. Forty-two years later, 46 new species and one subspecies have been described or revalidated.
Here we summarise the new species and contextualise them regarding their ecology, epidemiologic importance, and the obstacles
they pose to the control of Chagas disease around the world.
