this study describes and analyses the behavior of l. lurida flower visitors in fragments of tabuleiro lowland forest. this monoecious species flowered from october to january. the flowers opened between 5:30 and 10:00 a.m. and floral anthesis did not exceed one day. standardizing samples on flowers resulted in 172 bees, belonging to ten genera and 18 species. epicharis flava (42,3%), xylocopa frontalis (16,3%) and eufriesea surinamensis (11,6%) performed the highest relative frequencies, mainly occuring between 7:00 and 11:00a.m. centridini, euglossina and xylocopini bees took nectar on flowers and were considered effective pollinators. megachile collected pollen and also was potential pollinator. oxaea flavescens acted as nectar thief by piercing the flower hood. experiments of spontaneous autopollination indicated no fruit set and low fruit set (0,48%) was observed in flowers under natural conditions. as discussed for other zygomorphic flowers of lecythidaceae, the complex floral morphology restrict visitors to large or robust bees that can get into the flower through the floral hood. nevertheless centridini was the main pollinator group of l. lurida, which differs from the pollinators indicated in other studies on lecythidaceae in the amazonian region.
