“…The number of chromosomes of the P. megistus (2n = 21) and P. lutzi (2n = 24) can be used as a taxonomic tool to differentiate this species from all species of genus Panstrongylus (2n = 23), as well as allows distinguishing them from other 85 species of Triatominae subfamily that presents 22 (55 species) or 23 (30 species) chromosomes Bardella et al, 2016;Mendonça et al, 2016;Rosa et al, 2017). Jurberg et al (2001) based on chromatic and morphological analysis of only one specimen collected in Bahia described P. sherlocki as sister species of P. lutzi.…”

Scientific NoteCurrently, there are 153 species of triatomines, distributed in 18 genera, being all species considered as potential vector of Chagas disease Rosa et al., 2017). The genus Panstrongylus Berg, 1879 is composed of 15 species, being 14 species alive and one fossil. Cytogenetic analyses in Panstrongylus were initiated in 1950 with the karyotype description of P. megistus (Schreiber and Pellegrino, 1950). Until now the number of chromosomes in seven species of Panstrongylus was described, of which with the exception of P. megistus which has 21 chromosomes (2n = 18A + X 1 X 2 Y), all other species analyzed (P. chinai, P. geniculatus, P. howardi, P. lignarius, P. rufotuberculatus and P. tupynambai) have 23 chromosomes (2n = 20A + X 1 X 2 Y) (Schreiber and Pellegrino, 1950;Pérez et al., 2002;Panzera et al., 2010).Based on homogeneity of the number of chromosomes (2n = 23) and sex determination system (X 1 X 2 Y) of the genus Panstrongylus, Perez et al. (2002) suggested that these triatomines were possibly originated from ancestors of North America, because all species of South America [except Triatoma melanocephala (2n = 24), T. vitticeps (2n = 24) and T. tibiamaculata (2n = 23) (Alevi et al., 2012)] have 2n = 22 chromosomes and XY sex determination system (Panzera et al., 2010). These results were recently confirmed based on molecular analysis (Justi et al., 2014).Thus, in order to assist in the chromosomal and evolutionary knowledge of the genus Panstrongylus and Triatominae subfamily, this study aimed to analyze the karyotype of P. lutzi and compare with karyotypes already described for other species of the triatomines.One adult male of P. lutzi was collected in wild environment in the State of Bahia, Brazil (S 12.41'407 ", W 039.26'210" and elevation 167 meters). We justify that only one specimen was analyzed by the absence of P. lutzi in Brazilian insectaries and mainly by the difficulty of collecting and maintaining of these species in the laboratory, since for cytogenetic analyzes the insects might not be killed or fixed in alcohol (as occurs for molecular analysis). The seminiferous tubules of adult males were torn and fixed to a cover slip. They then underwent the cytogenetic technique of Lacto-acetic orcein (De Vaio et al., 1985 with modifications according to Alevi et al., 2012) and analyzed using a Jenaval light microscope (Zeiss). For the characterization of the karyotype were analyzed 50 mitotic metaphases (I and II).As well as was observed recently by Santos et al. (2016), P. lutzi presented a different karyotype of all species of the genus Panstrongylus, namely, 2n = 24 (20A + X 1 X 2 X 3 Y), being the Y sex chromosome heteropycnotic (Figure 1). This number of chromosomes is very peculiar because it was described to only three other species in subfamily Triatominae: T. melanocephala (Alevi et al., 2012), T. vitticeps (Schreiber and Pellegrino, 1950) and T. eratyrusiformis (Ueshima, 1966).Starting from the principle that the ancestral karyotype of Panstrongylus is 2n = 23 (Perez et al., ...

“…There are 79,000 species in the order Hemiptera (Stork ) and 7,000 species within the family Reduviidae (Weirauch et al ). Its subfamily Triatominae has 154 species (Rosa et al , Oliveira et al , Dorn et al , Poinar ), including three fossil species (Poinar , Poinar , Poinar ). The 151 remaining species encompass wild, domiciliary, and peri‐domiciliary triatomine bugs that are all capable of transmitting Trypanosoma cruzi to humans and 150 species belonging to 24 families of domestic or wild animals.…”

“…The 154 species of the Triatominae subfamily are distributed in 19 genera, including Panstrongylus, Rhodnius , and Triatoma , which harbor the most important species transmitting T. cruzi to humans (Rosa et al , Oliveira et al , Dorn et al , Poinar ). Nevertheless, the genus Mepraia, comprising M. gajardoi, M. parapatrica, and M. spinolai , has a particular relevance as all these species have only been observed in Chile (Porter , Frias et al , Frias ).…”

Introduction:Chagas disease surveillance requires current knowledge on synanthropic triatomines. We analyzed the occurrence and Trypanosoma cruzi infection rates of triatomine bugs in central Brazil, during 2012-2014. Methods: Triatomines were collected inside or around houses, and T. cruzi infection was determined by optical microscopy and conventional/quantitative polymerase chain reaction. Results: Of the 2706 triatomines collected, Triatoma sordida was the most frequent species in Goiás State, whereas Panstrongylus megistus predominated in the Federal District. Parasites identifi ed were T. cruzi, T. rangeli, and Blastocrithidia sp. Conclusions: P. megistus and T. sordida sustained the risk of T. cruzi transmission to humans in central Brazil.
