RESUMO
The stingless bee Melipona quinquefasciata is not included among the nine bee species of Melipona described in literature of NE Brazil. However, reports of some farmers raised suspicion on the occurrence of M. quinquefasciata in the state of Cearß, in NE Brazil. Investigations were carried out from July 1997 to September 2000, by means of trips to the areas of probable occurrence of this bee species. Results confirmed the presence of M. quinquefasciata in Cearß and determined its habitat along the chapada do Araripe (Araripe plateau) and all extension of planalto da Ibiapaba (Ibiapaba plateau), in altitudes between 600 and 900 m. Melipona quinquefasciata lives in the phytocoenosis of cerrado (Brazilian savanna), cerradõo (savanna forest) and carrasco (montane deciduous shrub vegetation) on the top of Araripe plateau, and only carrasco in the Ibiapaba plateau. Due to pressures caused by reduction of the area covered with native vegetation, large use of agrochemicals in anthropic areas and generalised predatory hunting of honey and beeswax, M. quinquefasciata is in risk of disappearing from the ecosystems of Araripe and Ibiapaba plateaus within a few years
