Abstract
Background: Among the vectors of Chagas disease (Hemiptera: Reduviidae: Triatominae), there are eighteen Rhodnius species described and some are difficult to identify. The aim of this article is to contribute to the specific identification of fourteen Rhodnius spp. through morphological characters of the external female genitalia.Methods: Female abdomens were cut transversely. The specimens were then prepared for examination by using scanning electron microscopy.Results: The careful examination of the dorsal, posterior and ventral sides revealed characteristics that allowed the identification of each of the fourteen species.Conclusion: The use of external female genitalia as characteristics are proposed as a tool for specifically identifying Rhodnius species, and an identification key for these species is presented.
