The bee community in a transition area of Cerrado-Amazônia in Bico-do-Papagaio region, in the of State of Tocantins, Brazil, was studied monthly from November, 1999 to November, 2000, by means of systematic sampling of bees in flowering plants, with the objective of obtaining information on its fauna composition. A total of 5534 individuals distributed in 83 species and 38 genera were collected. The largest abundance of individuals and richness of species was found in the family Apidae sensu Roig-Alsina & Michener. The genera with largest richness of species were Trigona (8), Megachile (7), Centris (6), Augochloropsis (5), Coelioxys (5), Paratetrapedia (5), and Xylocopa (5), while the most frequent species was Apis mellifera. The community structure followed the general pattern found in neotropical areas, showing many species with few individuals and few species with many individuals. The frequency, constancy, and dominancy of species are discussed, and the ecological indexes are presented.
