The Heteroptera have large number of described species, about 40,000, and diverse habitat and alimentary habits variables and therefore can live as parasites of birds and mammals, feeding on plant structures, mycelia of fungi or other arthropods. Despite these insects possess economic importance their studies are still few explored mainly in relation to testicular lobes and their phylogenetic relationships. Thus, this study aimed to understand and infer the phylogenetic relationships of species of Heteroptera belonging to the families Coreidae and Pentatomidae, from the fragments of mitochondrial genes (COI, Cyt b and 16S) and nuclear (28S and 18S) and molecular data associated morphological data and cytogenetic data. From the analysis it was possible to identify some relationships between families, tribes and genera, demonstrating the efficiency of genes and methodologies chosen. Families form two clades and these form brother group, most analyzes. Analyzing family Coreidae observed in most analyzes that form monophyletic groups. As the family Pentatomidae in all analyzes confirmed its monophyly. Observed clustering constant species of the same tribe and also congeneric groups with high bootstrap values. However, groupings among species of the same family, but different tribes still deserve to be better studied and explored. It was observed that with the inclusion of morphological and cytogenetic there was a better resolution of the results, especially among the tribes Pentatomini, Chlorocorini and Carpocorini (Pentatomidae). With the evolutionary analysis it was observed that some species grouped morphological characteristics more similar to species of other tribes than with your group. With this analysis it is possible to identify the relationships between families, tribes and genera and some similarities between species of different tribes grouped, however, there is need for a greater number of species and characters involved, because ...
