“…Schofield et al (1999) mencionaram que, embora tenham sido desenvolvidas explicações razoáveis para a compreensão do processo de domiciliação dos triatomíneos, as pesquisas ainda apresentam-se distantes da elucidação dos mecanismos que produziram este evento, o que seria um dos maiores desafios para a próxima década. Dez anos após, no centenário da descoberta da doença de Chagas, pouco se avançou para elucidar o mecanismo envolvido neste processo e paradoxalmente, a literatura apresentou uma série de episódios indicando que espécies de triatomíneos, até então restritas ao ambiente silvestre, vinham colonizando ou sendo frequentemente encontradas no ambiente domiciliar (Almeida et al 2000, Reyes-Lugo & Rodriguez-Acosta 2000, Costa et al 2003, Almeida et al 2009). …”

“…Costa and Felix (2007) described T. juazeirensis based on the T. brasiliensis population in Juazeiro/Bahia. Mendonça et al (2009) grouped T. sherlocki into the Brasiliensis subcomplex based on phylogenetic analyses with mitochondrial genes (16S and Cyt b). Costa et al (2013) revalidated and re-described the subspecies T. b. macromelanosoma based on melanin forms of T. brasiliensis encountered at housing (Galvão, 1955).…”

“…Brasiliensis subcomplex is a monophyletic group formed by the species T. b. brasiliensis, T. b. macromelasoma, T. juazeirensis, T. melanica, and T. sherlocki (Monteiro et al, 2004;Mendonça et al, 2009;Gardim et al, 2014;Justi et al, 2014). However, we emphasize that T. lenti and T. petrochiae were not used in any of the phylogenetic analyses described above (perhaps due to difficulties in sample collection).…”

ABSTRACT. The Brasiliensis subcomplex is a monophyletic group formed by the species Triatoma brasiliensis brasiliensis, T. b. macromelasoma, T. juazeirensis, T. melanica, and T. sherlocki. However, using cytogenetic data and experimental hybrid crosses, T. lenti and T. petrochiae were also grouped into this subcomplex. This study aims to analyze the properties of hotspot in the D2 domain of the nuclear gene 28S in all species of the Brasiliensis subcomplex as well as T. lenti and T. petrochiae. These species show two transversions at position 385 (G↔C and T↔G). We suggest that this mutation in haplotype 4 may be an initial molecular tool that supports the relationship of these species with the subcomplex. In addition to the transversion at haplotype 4, these species, aside from T. melanica, also possess a transversion at position 385 (G↔T) in haplotype 1. Thus, we describe the hotspot mutations of the D2 domain of the nuclear gene 28S for species in Brasiliensis subcomplex as follows: three transversions are present at position 385 of haplotypes 1 and 4, which are shared by members of the subcomplex as well as T. lenti and T. petrochiae. These transversions may be considered a synapomorphy between these species. However, we emphasize that new phylogenetic studies should be conducted to evaluate whether T. lenti and T. petrochiae are truly members of the Brasiliensis subcomplex.

Distribution of constitutive heterochromatin in Triatoma melanocephala (Hemiptera, Triatominae)

ABSTRACT. In principle, Triatoma melanocephala was included in the Brasiliensis subcomplex on the basis of morphological parameters and geographical layout, since there were no other relevant data available in the literature. On the basis of karyotype, it has been proposed to exclude T. melanocephala, as well as of T. vitticeps and T. tibiamaculata, from the subcomplex, which shows fragmentation of the X sex chromosomes, thereby approaching the species of North America. Therefore, the present study aimed to determine the pattern of constitutive heterochromatin of T. melanocephala to provide new data on the cytotaxonomy of this vector of Chagas disease and especially to try to relate this species to some group, complex or subcomplex of triatomine species, aiding in their classification. This species showed no constitutive heterochromatin in the autosomes or X sex chromosome, but only the Y sex chromosome. The number of chromosomes and heterochromatin pattern of T. melanocephala proved to be identical to that described for Panstrongylus lutzi. Thus, the present study demonstrated a tentative relationship between T. melanocephala and P. lutzi. However, we emphasize that other comparative studies should be conducted between these species, such as experimental crosses and molecular, enzymatic, morphological, and morphometric analyses to determine whether these species are actually evolutionarily related or if the number of chromosomes and the heterochromatin pattern emerged as homoplasies in T. melanocephala and P. lutzi.
