The geographical distribution of euglossine bees was determined in the State of Rio Grande do Sui, S'Brazil, by attracting males to chemical baits. 5 species of 3 genera were found, among them 2 new species. The distribution of euglossine bees coincides with the habitats of the Atlantic rain forest in the E and the subtropical rain forest in the W of the State. Due to its ample supply of plant species used by euglossine bees for food and fragrance collecting, the Atlantic rain forest sustains about 9 x more euglossine bees than does the subtropical rain forest. At the S' rim of the Serra Geral where these forest types intermingle, the W' and E' populations of euglossine bees overlap. In the Araucaria forest on the highlands no euglossine bee populations were found. The S' distributional limit of these bees in Brazil is given at about 30┬░ S latitude by the transition of the forest habitats in the N of Rio Grande do Sul to the Pampa and bushlands in the S.
