“…The main form of transmission of the protozoan is through hematophagous insects known as triatomines (Hemiptera, Triatominae) [1,2]. Currently 157 species of triatomines are known, divided in 18 genera and five tribes [3][4][5], being all considered as potential Chagas disease vectors.…”

The tribe Rhodniini is a monophyletic group composed of 24 species grouped in two genera: Rhodnius and Psammolestes. Rhodnius is a paraphyletic genus formed by 21 species. The event of paraphilia is supported by the greater evolutionary proximity of the species of the prolixus groups with the genus Psammolestes than with the other groups of Rhodnius. Based on this phenomenon, it was proposed the alteration of the genus of the species of Psammolestes to Rhodnius. Thus, we performed experimental crosses between Psammolestes spp. and R. neglectus to assess the degree of reproductive compatibility between Psammolestes and Rhodnius. Hybrids were not obtained for intergeneric crosses. Based on this, we have demonstrated that Rhodnius and Psammolestes have reproductive incompatibility. These data are important to confirm the validity of the specific status of Psammolestes, based on the biological concept of the species.

“…This confirms the specific status of the crossed species and demonstrates why there are no reports of natural hybrids between them. Based on these results, we suggest that the geniculatus clade may represent an important evolutionary model for Triatominae, highlighting the need for new studies with greater sample effort for the geniculatus clade (grouping the 17 species of Panstrongylus and the three of Nesotriatoma [ 1 – 3 ]).…”

“…The triatomines (Hemiptera, Triatominae) are insects of great importance to public health because all 154-living species of the subfamily Triatominae [ 1 – 3 ] are considered potential vectors of the protozoan Trypanosoma cruzi (Chagas, 1909) (Kinetoplastida, Trypanosomatidae) etiological agent of Chagas disease [ 4 ]. This disease is neglected, has no cure in the chronic phase (effective treatment being only possible in the early stages of infection) and affects about 6 to 7 million people worldwide [ 5 , 6 ].…”

“…Currently, the subfamily Triatominae is divided into 18 genera and five tribes (Alberproseniini, Bolboderini, Cavernicolini, Rhodniini and Triatomini) [ 1 , 7 ]. The Triatomini tribe is the most numerous (composed of 114 species grouped in ten genera [ 1 – 3 ]) and one of the most important from an epidemiological point of view [ 8 ]. Two most diverse genera in Triatomini ( Triatoma Laporte, 1832, and Panstrongylus Berg, 1879) are paraphyletic [ 8 , 9 ]; therefore, this tribe is divided into clades, groups, complexes and subcomplexes.…”

Trends in evolution of the Triatomini tribe (Hemiptera, Triatominae): reproductive incompatibility between four species of geniculatus clade

Background The geniculatus clade, composed by the rufotuberculatus, lignarius, geniculatus and megistus groups, relates evolutionarily the species of the genus Panstrongylus and Nesotriatoma. Several studies have shown that triatomine hybrids can play an important role in the transmission of Chagas disease. Natural hybrids between species of the geniculatus clade have never been reported to our knowledge. Thus, carrying out experimental crosses between species of the geniculatus clade can help to elucidate the taxonomic issues as well as contribute to the epidemiological knowledge of this group. Methods Experimental crosses were carried out between species of the megistus and lignarius groups to evaluate the reproductive compatibility between them. A phylogenetic reconstruction was also performed with data available in GenBank for the species of the geniculatus clade to show the relationships among the crossed species. Results Phylogenetic analysis grouped the species of the geniculatus clade into four groups, as previously reported. In the interspecific crosses performed there was no hatching of eggs, demonstrating the presence of prezygotic barriers between the crossed species and confirming their specific status. Conclusions In contrast to the other groups of the Triatomini tribe, as well as the Rhodniini, there are prezygotic barriers that prevent the formation of hybrids between species of the megistus and lignarius groups. Thus, the geniculatus clade may represent an important evolutionary model for Triatominae, highlighting the need for further studies with greater sample efforts for this clade (grouping the 17 species of Panstrongylus and the three of Nesotriatoma).

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.
