The subcomplex Triatoma brasiliensis comprises species: Triatoma brasiliensis brasiliensis, T. juazerensis, T. lenti, T. melanica T. melanocephala, T. petrochii, T. sherlocki, T. tibiamaculata e T. vitticeps. These species have many questions regarding its biology and phylogeny. Given this finding and making use of molecular studies, morphological and morphometric aspects were evaluated phylogenetic species of said complex. For both morphological characters of the female external genitalia, they were studied by means of scanning electron microscopy (SEM). By optical microscopy were developed morphometric studies: morphometric geometry heads and wings, measuring the length and width of the head, thorax length, abdomen and the three segments of the proboscis of adult females and males. Sequences of nuclear genes of internal transcribed spacers I and II were sequenced and the mitochondrial genes 12S, 16S, COI and Cytb were sequenced and evaluated with the aim to propose phylogenetic hypotheses for complex species.
