Abstract Background Triatoma brasiliensis is the primary vector of Chagas disease in Brazil's semi-arid regions, exhibiting adaptability to various environments, including domestic and peridomestic. Despite its significance, comprehensive genomic data for this subspecies remain limited. Methods We assembled complete mitochondrial genome T. b. using a combination Illumina Sanger sequencing technologies, latter being necessary obtain control region with eight primers designed study. The mitogenome was annotated identify gene content organization. Phylogenetic relationships were inferred conserved blocks 13 protein-coding genes 22 transfer RNA genes. For analysis, 18 representative triatomines near-complete mitogenomes selected, phylogenetic reconstruction performed maximum ikelihood method. Results spans 16,575 base pairs includes genes, two ribosomal consistent typical structure insect genomes. exhibited tandem inverted repeats arranged blocks, as observed other Reduviidae. Given limited availability mitogenomes, our analysis provided statistical support sister taxon infestans , forming well-supported clade that vitticeps . Conclusions provides insights into systematics, biology, genomics triatomine species while also enhancing understanding their evolutionary relationships. However, number available particularly South American species, underscores need further efforts improve resolution comparative studies. Graphical
