The study was carried out at three areas of the Guaribas Biological Reserve, one area with typical Atlantic rain forest vegetation, one with a Savanna-like vegetation typical of coastal ecosystems, locally known as 'Tabuleiro', and another called Transition area, containing a mosaic of the two former types of vegetation. A total of 2314 individuals belonging to 11 species of Euglossina were sampled, using traps. Six artificial fragrances were used as baits: eugenol, cineol, skatol, beta ionone, benzyl acetate, and vanillin. From the Forest area 850 males belonging to 11 species were sampled, from the Savanna-like vegetation 737 males belonging to five species were sampled, and from the Transition area 727 males belonging to six species were sampled. The highest diversity (H' = 0.94) and richness were obtained from the Forest area. The Sørensen binary similarity coefficient showed that regarding species composition Savanna-like vegetation and Transition were the most similar areas (Ss = 0.92). The Morisita similarity coefficient showed that Forest and Transition areas were identical (Cmh = 1) regarding relative abundance of species. Transition area is more similar to an open area of Savanna-like vegetation, in terms of composition and diversity, and more similar to the Forest area, regarding relative abundance, suggesting that some Forest species also forage in the Transition area.
