Rhodnius barretti, a new species of Triatominae (Hemiptera: Reduviidae) from western Amazonia.

摘要: Rhodnius barretti , a new triatomine species, is described based on adult specimens collected in rainforest environments within the Napo ecoregion of western Amazonia (Colombia and Ecuador). R. resembles robustus s.l. but mitochondrial cytochrome b gene sequences reveal that it strongly divergent member “robustus lineage”, i.e., basal to clade encompassing nasutus neglectus prolixus five members species complex. Morphometric analyses also consistent divergence from including head and, as previously shown, wing shape length ratios some anatomical structures. occurs, often at high densities, Attalea butyracea Oenocarpus bataua palms. It strikingly aggressive adults may invade houses flying peridomestic must therefore be regarded potential Trypanosoma cruzi vector ecoregion, where Chagas disease endemic.
