| A higher-level classification of bees, in which the entire group is treated as a single family - the Apidae - is advocated here. A total of seven subfamilies, 51 tribes and 27 subtribes are recognized. These subfamilies correspond to the families adopted in the traditional classification. Although the proposed changes do not involve any major rearrangement, basically only changing the rank given to the main groups, the new system makes the classification of bees more consistent with that adopted for other major groups of aculeate Hymenoptera. It also departs from the 19th century practice, perpetuated in the traditional classification, of giving family-status to the main groups of bees. A correspondence table associating the taxon names used in the current... |

| The trap-nesting bees of Guaribas Biological Reserve were studied during one year. Three areas with different vegetation types were sampled, open savanas, closed forest, and a mosaic of these two types. Twelve species of trap-nesting bees were observed, four of which are parasites. The most abundant species were Centris tarsata (Smith, 1879), C. analis (Fabricius, 1804), Tetrapedia diversipes KJug, 1810, and Mesocheira bicolor (Fabricius, 1804). Nesting of Centris tarsata and Mesocheira bicolor occurred mainly during the dry season, while Centris analis and Tetrapedia diversipes did not show any seasonal preferences. Mesocheira bicolar occurred only in the nests of C. tarsata, parasitizing more than 50% of the nests and representing 23.2% of the... |

| This paper reports the results concerning collection of Euglossinae bees in a mangrove ecosystem in Valença(13º22'08"S and 39º04'20"W), Bahia. These samples were made twice a month, for a year. The chemical baits Citronella, Eucalyptol, Eugenol, Metyl Salicylate and Vanillin attracted 1,144 specimens distributed among twelve species and two genera: Eulaema (Lepeletier, 1841) and Euglossa (Latreille, 1802). The predominam bee species was Eulaema nigrita (Lepeletier, 1841) consisting of 49.4% of the collected specimens, followed by Euglossa cordata (Linnaeus, 1758) with 44.88%, Euglossa imperialis (Cockerell, 1922) with 2.4% and Eulaema meriana flavescens (Friese, 1899) with 1.6%. Theothers species, considering sporadic visitors, Euglossa securigera... |

| The architecture and biology of Euplusia mussitans (Fabricius, 1787) nests were investigated, using trap nests made by wood, which were randomly distributed in a fragment of a coastal sand dunes, in Salvador, Bahia. Brazil (12º56'S and 38º21'W). 10 nests were found in cavities with 1.5 cm in diameter. From them emerged 10 females and 16 males (Sex ratio = 0,38). The nest cells were made of small pieces of bark cemented together with resin. The number of cells in the nests varied from 2 to 4, with females cells at the inner end and males cells towards the entrance. No significant difference was observed (t= 0.7274, P > 0.05) between the medium size for males (6.3 mm ± 0.16) and for females (6.4 mm ± 0.29). The development time of females was longer than... |

| Male euglossine bees attracted to cineole, vanillin, methyl salicylate, eugenol and benzyl benzoate, were collected from October 1995 to September 1996, twice a month, between 06.00 and 12.00 hours, at the Companhia Vale do Rio Doce Forest Reserve, Buriticupu-MA. It were sampled 1740 individuals, 37 species and 4 genera. Euglossa was the most abundant genus (23 species), followed by Eufriesea (8), Eulaema (4) and Exaerete (2). The most frequent species were Euglossa pleosticta (33% of the collected individuals), Euglossa truncata (12,7%), Euglossa avicula (6,3%), Eufriesea superba (5,2%), Euglossa fimbriata (4,8%) Euglossa violaceifrons (4,4%), Eulaema nigrita (4,1%), Euglossa cordata (4,0%), Eulaema meriana (3,4%). Cineole attracted 66% of males and 70%... |

| ABSTRACT Elaiophores are floral glands that secrete non-volatile oils as a reward for their pollinators. Their secretions mediate a specialized interaction between oil-producing plants and a few species of oil-collecting bees - Apidae and Melittidae. The present review focuses on the morphological and functional aspects of these secretory structures. We also provide information on their chemistry and pollination ecology. Our survey is organized taxonomically among the plant families for which elaiophore occurrence has been confirmed -for the monocots, Iridaceae and Orchidaceae, and for the eudicots, Calceolariaceae, Cucurbitaceae, Krameriaceae, Malpighiaceae, Plantaginaceae, Primulaceae, Scrophulariaceae, Solanaceae and Stilbaceae. Most oil flowers are... |

| ABSTRACT Heteranthery, the presence of different types of stamens in a flower, may reduce the conflict between pollinators and plants by ensuring the resource for the pollinator without drastically affecting the availability of viable male gametes for fertilization, according to the division-of-labor hypothesis. We investigated whether the poricidal anthers of Senna pendula, a buzz-pollinated heterantherous species, present morphological and physiological differences among pollen grains from the three sets of stamens. We compared quantity, ornamentation, size and fecundity of pollen from long, medium and short stamens. The short feeding stamens produced larger but fewer pollen grains than the long pollinating stamens, which produced smaller pollen grains... |

| The Solanaceae family has a wide distribution, mainly in the tropical and subtropical areas of South America. Solanum L. is one of the most important genera of the family with approximately 1,200 species. The objective of this work was to study the floral biology, pollen morphology as well as to investigate the bee visitors of S. stramoniifolium. Preliminary data indicate the presence of one species of stinging bee and four species of stingless bees as visitors to S. stramoniifolium. The pollen of S. stramoniifolium is tricolporate and psilate or without ornamentation. In a word, S. stramoniifolium constitutes a potential source of pollen for different species of bees with and without sting, providing an interesting field for germination studies,... |

| This is the first systematic survey of bees in the Pantanal wetland, Brazil. We recorded bee species and their floral resources within grassland and natural forest edge habitats in the Pantanal. Surveys were conducted during two to four-days per month, for a total of 12 months. Overall, we recorded 56 bee species visiting a total of 63 flowering plants. Asteraceae and Fabaceae presented the highest number of visited species, however Hyptis suaveolens (Lamiaceae) was the plant most visited by different bee species (18). The most generalist native bee was Trigona fuscipennis visiting a total of 17 flowering plant species. Apis mellifera, an exotic bee, visited 27 species. We also report the overlap (37.5%) in the use of floral resources between the exotic... |

| Floral visitors of seven species of Oxypetalum were registered in Viçosa, State of Minas Gerais. O. appendiculatum, O. banksii subsp. banksii, O. alpinum var. alpinum and O. pachyglossum are pollinated by wasps, being Polybia ignobilis (Vespidae) a pollinator of these four species. It seems that P. ignobilis promotes interspecific pollinations mainly between O. alpinum var. alpinum and O. pachyglossum, two species with very similar floral morphology. O. jacobinae, O. mexiae and O. subriparium are pollinated by bees. Wasps and bees carry one, two, three or several pollinaria in the mouthparts. O. mexiae, an endemic species in Viçosa, seems to present reproductive limitations, since its flowers are seldom visited. |
