Ecological niche modelling was used to predict the potential geographical distribution of Rhodnius nasutus Stål and Rhodnius neglectus Lent, in Brazil and to investigate the niche divergence between these morphologically similar triatomine species. The distribution of R. neglectus covered mainly the cerrado of Central Brazil, but the prediction maps also revealed its occurrence in transitional areas within the caatinga, Pantanal and Amazon biomes. The potential distribution of R. nasutus covered the Northeastern Region of Brazil in the semi-arid caatinga and the Maranhão babaçu forests. Clear ecological niche differences between these species were observed. R. nasutus occurred more in warmer and drier areas than R. neglectus. In the principal component analysis PC1 was correlated with altitude and temperature (mainly temperature in the coldest and driest months) and PC2 with vegetation index and precipitation. The prediction maps support potential areas of co-occurrence for these species in the Maranhão babaçu forests and in caatinga/cerrado transitional areas, mainly in state of Piaui. Entomologists engaged in Chagas disease vector surveillance should be aware that R. neglectus and R. nasutus can occur in the same localities of Northeastern Brazil. Thus, the identification of bugs in these areas should be improved by applying morphometrical and/or molecular methods.

Lettre autographe signée. - Date restituée d'après le contexte : "je suis en train de monter un grand concert spirituel le samedi saint (23)" , ce qui autorise l'année 1859, où Berlioz dirige "L'Enfance du Christ" à l'Opéra-Comique le 23 avril. - A rapprocher d'une lettre à Camille Pal, où Berlioz s'exprime dans ses termes à peu près identiques (C.G. n° 2364). - Lors du concert à Baden le 29 août 1859, Berlioz dirigea des extraits des "Troyens" et non "Roméo et Juliette"
