Abstract

Currently, there are 158 valid species of triatomines, all of which are potential vectors of , the etiological agent of Chagas disease. The correct taxonomic identification of triatomines is essential since each species hos a different epidemiological importance. The aim of the study is to compare five species of South American . Here we present a comparative study of terminal abdominal segments in females by scanning electron microscopy (SEM) of the species , , var. , , and . The results showed diagnostic characters for the studied species. The dorsal view featured more valuable characters, with seven informative characters. Similarities were observed among , var. , and , and between and , correlating with previous studies. Thus, female genital characters proved to be reliable and useful in the diagnosis of the species studied here; additional studies, along with other sets of behavioral, morphological, and molecular data, helped to reinforce the hypotheses found here.
