| Coletas sistemáticas de abelhas em uma área restrita no Parque Estadual de Vila Velha, Paraná, no período de outubro de 2002 a outubro de 2003, resultaram em 1552 espécimes pertencentes a 181 espécies. Estas espécies estão distribuídas em 58 gêneros, 24 tribos e 5 subfamílias. As plantas visitadas correspondem a 113 espécies, em 72 gêneros e 38 famílias. Megachile com 20 espécies foi o gênero mais rico e Ceratina o gênero mais abundante dentre os gêneros nativos. Apis mellifera foi a espécie mais coletada, correspondendo a 28% do total de indivíduos, e Bombus atratus foi a espécie mais abundante dentre as abelhas nativas. A riqueza e a equitabilidade nos meses foram variáveis, sendo março o mais rico e novembro o de maior equitabilidade. Apesar de... |

| A new species of Eufriesea Cockerell (Hymenoptera, Apidae) from northeastern Brazil. Eufriesea pyrrhopyga sp. nov. a short-tongued Eufriesea is described as a new species. It can be easily recognized for its predominantly violet lower frons and thorax, violet tergum 1 contrasting with the strong reddish coloration on the lateral portions of terga 2 to 4 and on entire terga 5 and 6, and head pubescence with contrasting colors, white on the lower two-thirds of the face and black on upper frons and vertex. This new species, collected in Recife (Pernambuco, Brazil), apparently is restricted to the Pernambuco endemic center, and seems to be highly endangered. |

| Bee fauna and associated flora from a grassland site in Brazil, surveyed 40 and 20 years ago, were newly surveyed with comparable methodology to evaluate changes in the bee fauna of this site, considering that human population and urbanization has exponentially increased in the last 40 years. In general, bee species richness has declined in 22%, as well as their abundance. Some of the previously abundant species are now absent, including Bombus bellicosus Smith, 1879, Gaesischia fulgurans (Holmberg, 1903) and Thectochlora basiatra (Strand, 1910). No particular trend of differential decrease among either taxonomic or functional groups was observed, except for a minor increase in the proportion of oligolectic species and a 50% reduction in the number of... |

| 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... |

| For the first time, confirmed host records are reported for the monotypic Ericrocidini genus Aglaomelissa Snelling & Brooks, 1985. Aglaomelissa duckei (Friese, 1906) emerged from trap-nests of Centris (Heterocentris) analis (Fabricius, 1804) and C. (Heterocentris) terminata Smith, 1874 from two sites in the Brazilian Amazonian region. The parasitism ratio caused by A. duckei was high, varying from 80 to 100% of the brood cells in a single trap-nest. Also, a compilation of the known host records for the species of Ericrocidini is presented and host-parasite associations are discussed. Host associations are known for seven of the 11 genera and about 17 of the 42 species of the tribe, involving a total of 34 confirmed or putative host species of... |

| O nome limao tem sido usado para espécies distintas do gênero Lestrimelitta. O material-tipo de Smith depositado no The Natural History Museum (Londres) foi examinado. A operária de L. limao é descrita e o lectótipo para Trigona limao Smith, 1863 é designado. Esta espécie encontra-se restrita aos cerrados da porção central do Brasil, de São Paulo ao Maranhão. Distingue-se de outras espécies pelos seguintes caracteres diagnósticos: vértice com pouquíssimas cerdas eretas, muito finas e curtas, restritas à região interocelar; bordo anterior do mesoscuto com cerdas eretas castanhas nas laterais; laterais do mesepisterno com cerdas eretas esparsas e restritas à porção ventral e curvatura entre porções lateral e ventral, tornando-se mais longas próximo à base da... |

| Notes on the systematics of the orchid-bee genus Eulaema (Hymenoptera, Apidae). The classification of the genus Eulaema is modified in order to make it congruent with recent phylogenetic hypotheses based on molecular data. The speciosa group, containing E. peruviana, E. speciosa and related species, is removed from E. (Eulaema) and transferred to E. (Apeulaema). New morphological characters are presented to support the revised scope of the subgenera and their diagnostic features are revised. Six species groups are recognized herein: two in E. (Apeulaema) and four in E. (Eulaema). A list of valid species in each species group and an identification key to males of each of the subgenera and species groups are provided. Finally, an older overlooked designation... |

| On the identity of Melipona torrida Friese (Hymenoptera, Apidae). Melipona marginata var. torrida Friese, 1916, described from three workers putatively collected in Costa Rica, never had its identity properly recognized. Since its original description, no additional specimens have ever been collected in Costa Rica. It is argued here that Melipona torrida was based on mislabeled specimens and corresponds to Melipona marginata obscurior Moure, 1971, a form known only from southern Brazil, Argentina and Paraguay. A lectotype is designated for Melipona torrida and notes on the type material of Melipona marginata obscurior are provided. Other known examples of species described from mislabeled specimens in Friese's Zur Bienenfauna von Costa Rica are discussed.... |

| Phylogeny and revision of the bee genus Rhinocorynura Schrottky (Hymenoptera, Apidae, Augochlorini), with comments on its female cephalic polymorphism. A taxonomic revision and a phylogeny for the species of Rhinocorynura are provided. Six species are recognized: R. briseis, R. crotonis, R. inflaticeps and R. vernoniae stat. nov., the latter removed from synonymy with R. inflaticeps, in addition to two newly described species, R. brunnea sp. nov. and R. viridis sp. nov. Lectotypes for Halictus crotonis Ducke, 1906 and Halictus inflaticeps Ducke, 1906 are hereby designated. Another available name included in Rhinocorynura, Corynuropsis ashmeadi Schrottky, 1909, is removed from the genus and treated as species inquerenda in Augochlorini. Rhinocorynura is... |

| Revisão taxonômica das espécies de abelhas do gênero Lestrimelitta Friese (Hymenoptera, Apidae, Meliponina) que ocorrem no Brasil. Com base em caracteres morfológicos, como aqueles relacionados com a pilosidade, o formato do espiráculo propodeal, as distâncias interorbitais e o comprimento do esporão mesotibial, são reconhecidas catorze espécies, seis das quais novas para a Ciência: L. ciliata. sp. nov., L. maracaia sp. nov., L. similis sp. nov., L. spinosa sp. nov., L sulina. sp. nov. e L. tropica sp. nov. São designados lectótipos para Trigona (Lestrimelitta) limao var. rufipes Friese, 1903 e Trigona (Lestrimelitta) limao var. rufa Friese, 1903.
