Characterization of External Female Genitalia in Five Triatoma Laporte Species of South America (Hemiptera: Reduviidae: Triatominae)

Currently, there are 158 valid species of triatomines, all of which are potential vectors of Trypanosoma cruzi, 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 stud...

description Currently, there are 158 valid species of triatomines, all of which are potential vectors of Trypanosoma cruzi, 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 Triatoma. Here we present a comparative study of terminal abdominal segments in females by scanning electron microscopy (SEM) of the species Triatoma delpontei, T. jurbergi, T. infestans var. melanosoma, T. platensis, and T. vandae. The results showed diagnostic characters for the studied species. The dorsal view featured more valuable characters, with seven informative characters. Similarities were observed among T. delpontei, T. infestans var. melanosoma, and T. platensis, and between T. jurbergi and T. vandae, correlating with previous studies. Thus, female genital characters proved to be reliable and useful in the diagnosis of the Triatoma species studied here; additional studies, along with other sets of behavioral, morphological, and molecular data, helped to reinforce the hypotheses found here.
