| Abstract | Triatoma guazu Lent and Wygodzinsky and Triatoma williami Galvão, Souza, and Lima
(Hemiptera: Triatominae) are found in human dwellings and are potential vectors of the protozoan
Trypanosoma cruzi, the etiological agent of Chagas disease. Triatoma guazu was described based
solely on a single female specimen, from the municipality of Villarica, Guairá Department, Paraguay,
and posteriorly, a male from Barra do Garças, Mato Grosso, Brazil was described and designated
as the allotype of this species. Triatoma williami is found in the central-west of Brazil between
Goiás, Mato Grosso, and Mato Grosso do Sul. However, the taxonomic “status” of these species
is questioned. Previous studies indicate the lack of isoenzymatic diagnostic loci, morphometric
similarity, low genetic divergence, and close evolutionary relationship of these species. In this study,
we compared the morphology, morphometry, and mitochondrial DNA fragments of the populations
of the two species. The morphological diagnostic characteristic among these species is the difference
in the connexivum spots pattern, which has been recognized as a phenotypic variation that exists
among populations resulting from ecological diversity. Furthermore, our analysis also revealed the
morphometric similarity and low genetic divergence between these species. Therefore, in the present
paper, we formally propose T. guazu as a junior synonym of T. williami. | pt_BR |
