The objective of this work was to contribute to the knowledge of Euglossina bees ecology in the Roraima State, Amazon Region, Brazil. A study of the Euglossina bees fauna from Serra do Tepequem, municipality of Amajari was made. The collects of Euglossina bees were carried out in March to May 2011 using traps made with PET bottles containing aromatic baits. The abundance and diversity of Euglossina were verified in primary forest edge, primary forest inside, and in a fragment of altered forest on top of the mountain. About 243 specimens of Euglossina bees were collected, and distributed among 24 species of three genera: Euglossa, Eulaema and Exaerete. The predominance was the genus Euglossa followed by Eulaema and Exaerete. The most abundant species was Euglossa imperialis followed by Eulaema meriana and Eulaema nigrita. The greatest species richness was observed on the edge and within the primary forest. In spite of have not been verified difference in average abundance of the species between the sites was noted a decrease of diversity in altered forest fragment, concluding that forest fragmentation is harmful to the diversity of this group of bees.
