Phylogenetic positioning of Trypanosoma cruzi parasites found in a darker chromatic variation of Rhodnius pallescens from Santa Fe, Veraguas Province, Panamá. The phylogenetic tree is based on cytochrome c oxidase subunit 2 sequences. The trees were constructed using the neighbor-joining method and numbers on the tree indicate bootstrap values for branch points. The analyses included reference sequences of T. cruzi discrete typing units (DTUs) (accession numbers in parentheses). The gray shaded portion of the tree corresponds to the sequences generated in this study
