Article Synopsis
- The study demonstrated that despite morphological similarities, distinct genetic and reproductive barriers exist between the species, confirming their separate identities.
- Experimental crossbreeding between these species showed no hybridization, indicating prezygotic reproductive isolation.
- The findings suggest that one species is the most evolved member of the complex, rather than just a chromatic variant of another.
Triatomines are hematophagous insects of great epidemiological importance, since they are vectors of the protozoan Trypanosoma cruzi, the etiological agent of Chagas disease. Triatoma brasiliensis complex is a monophyletic group formed by two subspecies and six species: T. b.

- The text discusses a crucial and diverse genus of insects from an epidemiological standpoint, highlighting the challenges in identifying its species.
- It details morphological, histological, and morphometric studies that help differentiate specific triatomine species that coexist in the same geographic areas and have disease vector potential.
- The findings emphasize the taxonomic validity of certain species and contribute new information useful for ongoing discussions in systematics.

In Latin America, Chagas disease has been mostly transmitted to humans by contact with the feces or urine of triatomine species infected with the protozoan Trypanosoma cruzi. There are currently 156 species in the subfamily Triatominae, distributed in 18 genera and five tribes. The prolixus group of the genus Rhodnius is composed of 11 species.

- There are 156 species in the subfamily Triatominae, all potential vectors for Chagas disease, classified into 18 genera and five tribes, with Triatoma being a paraphyletic group.
- The Triatoma brasiliensis complex, a monophyletic group, includes eight species, and experimental crosses among these species have been conducted to explore systematic and evolutionary questions.
- The study found that hybrids displayed varying segregation patterns of phenotypic traits, emphasizing the need for integrative taxonomy to accurately identify Chagas disease vectors amid potential natural hybridization.
