摘要
Chagas disease (CD) is a neglected illness affecting approximately seven million individuals, with vector transmission occurring via triatomine bugs. The Rhodniini tribe comprises 24 species, grouped into the and genera. Given the importance of accurately identifying CD vectors, the taxonomy of spp. was revisited using morphological and morphometric data. Specimens of , , and were collected, and the morphological characteristics of the head, thorax, abdomen, and eggs were analyzed. Morphometric studies of eggs were also conducted. Dichotomous keys allowing for the differentiation of spp. were elaborated based on adult insect and egg morphological characteristics. Through these studies, it was possible to differentiate the three species and confirm that this genus should not be classified under the genus, contributing to Rhodniini taxonomy.
