“…Cytotaxonomy was started with Ueshima [179] by proposing the application of cytogenetic studies of chromosomes to differentiate morphologically related species. Later, the use of chromosomal analyses-such as karyotypes [180][181][182][183]-the constitutive heterochromatin pattern [156,184,185], the heterochromatin base pair composition [186][187][188], and the location of the nucleolar organizing region [139,156,189], assisted in the correct identification and classification of triatomines. Recently, dichotomous keys have been proposed based on cytogenetic data [190][191][192][193].…”

Trends in Taxonomy of Chagas Disease Vectors (Hemiptera, Reduviidae, Triatominae): From Linnaean to Integrative Taxonomy

Chagas disease is a neglected tropical disease caused by the protozoan Trypanosoma cruzi and transmitted mainly by members of the subfamily Triatominae. There are currently 157 species, grouped into 18 genera and five tribes. Most descriptions of triatomine species are based on classical taxonomy. Facing evolutionary (cryptic speciation and phenotypic plasticity) and taxonomic (more than 190 synonymizations) problems, it is evident that integrative taxonomy studies are an important and necessary trend for this group of vectors. Almost two-and-a-half centuries after the description of the first species, we present for the first time the state-of-the-art taxonomy of the whole subfamily, covering from the initial classic studies to the use of integrative taxonomy.

“…Triatoma is divided into nine specific complexes based on phenotypic similarity, geographic distribution, phylogeny, epidemiological importance [ 7 ], and cytogenetic aspects [ 8 , 9 ]. However, there is still no consensus regarding the characteristics that define these complexes, and new studies are needed to corroborate or refute these groupings [ 10 , 11 ].…”

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 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.
