Trypanosoma rangeli is a species of hemoflagellate excavate parasites of the genus Trypanosoma. Although infecting a variety of mammalian species in a wide geographical area in Central and South America, this parasite is considered non-pathogenic to these hosts. T. rangeli is transmitted by bite of infected triatomine bugs of the Reduviidae family, commonly known as barbeiro, winchuka (vinchuca), chinche, pito ou chupão. The only triatomine insects that T. rangeli is only able to produce infective forms in are those from the genus Rhodnius.
