In order to clarify the systematic status and infer the evolutionary relationships of these vectors of Chagas disease, we performed a comparative analysis of their antennal phenotype, taking also into account Triatoma wygodzinskyi, a possible sister species. The comparison was based on sensilla arrays on the three distal segments of the antenna. Our results show a close similarity between T pseudomaculata and T wygodzinskyi antennal phenotypes, and significant differences with T maculata. The interpopulation study reinforces the idea that T pseudomaculata (arboricolous species) and T wygodzinskyi (rupicolous species) would originate from a common ancestor. specialized Triatoma maculata complex Triatoma pseudomaculata Triatoma maculata Triatoma wygodzinskyi antennal phenotype sensilla Brazil 052 080 106 1 16-21 2008 0001-706X https://www.documentation.ird.fr/hor/fdi:010042556 10.1016/j.actatropica.2007.12.010 0001-706X [F B010042556] https://www.documentation.ird.fr/hor/fdi:010042556 https://www.documentation.ird.fr/intranet/publi/2008/05/010042556.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2008-05-30 2017-08-23 fdi:010042556 fre
