Triatoma chiarii sp. nov. (Hemiptera, Reduviidae, Triatominae): a new species in the Triatoma brasiliensis complex from Rio Grande do Norte state, Brazil.

ABSTRACT:

Background

A new triatomine species was discovered in the semiarid Caatinga region of Rio Grande do Norte, Brazil, where it coexists with Triatoma brasiliensis in both natural and artificial habitats.

Methods

Triatomine specimens were captured in peridomestic and sylvatic environments in Rio Grande do Norte. Their identification was based on a combination of analyses, including morphology using dichotomous keys, head and hemelytron morphometry, and phylogeny using cytochrome b and internal transcribed spacer markers.

Results

The new species exhibits morphological traits that are intermediate between those of Triatoma brasiliensis and Triatoma petrocchiae, but has distinct characteristics, leading to its designation as Triatoma chiarii sp. nov. Geometric morphometric a
