Analysis of\n                    <jats:italic>cox1<\/jats:italic>\n                    sequences revealed high similarity with reference sequences from the Brazilian Amazon, low nucleotide divergence (0\u20130.55%), and the presence of four haplotypes, including shared haplotypes between the two study areas.
