Mitochondrial Genes Reveal Triatoma jatai as a Sister Species to Triatoma costalimai (Reduviidae: Triatominae)

Triatoma jatai was described using a set of morphological structures from specimens collected in Parana municipality of Tocantins State, Brazil. Under a Bayesian framework and using two mitochondrial genes (16S and COI), phylogenetic analysis recovered T. jatai as a sister species to Triatoma costalimai with higher genetic distances than between other well-recognized species. Our results agree with previous suggestions based on morphometric analysis. In the light of the non-monophyly of Matogrossensis subcomplex, the inclusion of T. jatai shall be considered for reevaluating this group.
