“…The subfamily Triatominae include 18 genera comprising 152 species, 20 of which belong to the genus Rhodnius (Galvão 2014, Mendonça et al 2016, Souza et al 2016). The difficulties involved in the specific identification of Rhodnius have already been noted by Neiva and Pinto (1923), as well as by Rosa et al (2012) and Souza et al (2016).…”

“…Chagas disease vectors belong to the order Hemiptera, the suborder Heteroptera, the family Reduviidae and, the subfamily Triatominae [2]. This subfamily is composed of 151 species distributed across 18 genera and five tribes [2–5], and all species (nymphs and adults of both sexes) are considered to be potential vectors of T. cruzi .…”

Triatoma vitticeps subcomplex (Hemiptera, Reduviidae, Triatominae): a new grouping of Chagas disease vectors from South America

et al. 2017

BackgroundTriatomines have been grouped into complexes and subcomplexes based largely on morphological and geographical distribution. Although these groupings are not formally recognised as taxonomic ranks, they are likely monophyletic. However, recent studies have demonstrated that some subcomplexes from South America did not form monophyletic groups, and reorganisations have been suggested. One suggested reorganisation is to exclude Triatoma vitticeps, T. melanocephala, and T. tibiamaculata from the T. brasiliensis subcomplex. However, T. vitticeps and T. melanocephala exhibit several similar characteristics, including morphologic, cytogenetic, and phylogenetic features, a factor which supports the creation of a new subcomplex. Thus, this study aimed to describe the T. vitticeps subcomplex.Results T. vitticeps and T. melanocephala are sister species and share a phylogenetic relationship, several similar morphological characteristics, the same composition of constitutive heterochromatin (Xs CG-rich and Y AT-rich), the same karyotype (2n = 20A + X1X2X3Y), and the same meiotic behaviour during spermatogenesis. Based on karyosystematics, for example, the T. vitticeps subcomplex may differ from all of the other subcomplexes from South America, as well as from the Rhodniini tribe and the genus Panstrongylus. We argue that the case of agmatoploidy involving the X chromosome was responsible for the karyotype divergence of this subcomplex in relation to the other South America subcomplexes.ConclusionsBased on the phenotypic characteristics (morphology) and genotypes (cytogenetics and molecular features), we propose the creation of the monophyletic T. vitticeps subcomplex, which we believe is distinct from all other subcomplexes from South America.

“…The 3 female specimens were studied at the Entomology Laboratory of the Escritório Regional de Saúde de Barra do Garças (ERSBG) of the Secretaria de Estado de Saúde de Mato Grosso, Brazil (SESMT), and identified as P. diasi. The identification was made using the dichotomous keys of Lent and Wygodzinsky (1979) and Galvão and Dale (2014).…”

Panstrongylus diasi Pinto & Lent, 1946, previously known from throught the Brazilian center-west, is reported for the first time in Mato Grosso state, Brazil. We found 3 specimens, 1 of them from an urban area of Barra do Garças. The new record of P. diasi is important for the understanding of the epidemiology of Chagas disease, mainly because this species is found naturally infected with Trypanosoma cruzi (Chagas, 1909). Studies on the ecology, biogeography, and vector-host/parasite interactions of P. diasi are essential.
