Notes on oil sources for the bee genus Caenonomada(Hymenoptera, Apidae, Tapinotaspidini)
Provedor de dados: 92
Autores: Aguiar,Antonio J. C.; Melo,Gabriel A. R.
It is reported for the first time oil collecting by bees of the genus Caenonomada on flowers of Plantaginaceae. Females of Caenonomada unicalcarata were observed collecting oil on flowers of Angelonia cornigera, and males and females of Caenonomada bruneri and C. aff. unicalcarata were observed on flowers of Angelonia and Monopera (Plantaginaceae). The record of Caenonomada on Plantaginaceae suggests the use of trichomatic oil glands as a primitive condition in the tribe Tapinotaspidini.

Females of Tapinotaspoides, a genus in the oil-collecting bee tribe Tapinotaspidini, collect secretions from non-floral trichomes (Hymenoptera, Apidae)
Provedor de dados: 92
Autores: Melo,Gabriel A. R.; Gaglianone,Maria Cristina.
Harvesting of secretions from non-floral trichomes by females of Tapinotaspoides serraticornis is reported for the first time. The females exhibit a type of mopping behavior using the fringes of long, wavy setae along the posterior margins of their metasomal sterna. Our observations indicated a wide range of host plants used as sources for these secretions, including Waltheria (Sterculiaceae), Tibouchina (Melastomataceae), Sida (Malvaceae), Jacquemontia (Convolvulaceae), and unidentified species of Commelinaceae and Cyperaceae.

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...

A new species of Eufriesea Cockerell (Hymenoptera, Apidae, Euglossina) from northeastern Brazil
Provedor de dados: 92
Autores: Faria,Luiz R. R.; Melo,Gabriel A. R.
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.

On the identity of Melipona torrida Friese (Hymenoptera, Apidae)
Provedor de dados: 92
Autores: Melo,Gabriel A. R.
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....

A new cluster-brood building species of Plebeia (Hymenoptera, Apidae) from eastern Brazil
Provedor de dados: 92
Autores: Melo,Gabriel A. R.; Costa,Marco A.
A new species of Plebeia, the second largest genus of stingless bees in the Neotropical region, is described from eastern Brazil. Plebeia grapiuna sp. nov., known only from the lowland forests of southern Bahia, is most similar to P. lucii Moure, a species recently described from Minas Gerais. The lack of yellow marks and the smoother integument of the frons and mesoscutum in P. grapiuna sp. nov. distinguish them. Main features of the nesting habits of the new species are described and illustrated.

Changes in wild bee fauna of a grassland in Brazil reveal negative effects associated with growing urbanization during the last 40 years
Provedor de dados: 103
Autores: Martins,Aline C.; Gonçalves,Rodrigo B.; Melo,Gabriel A. R.
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...

New host records of Aglaomelissa duckei and a compilation of host associations of Ericrocidini bees (Hymenoptera: Apidae)
Provedor de dados: 103
Autores: Rocha-Filho,Léo C.; Morato,Élder F.; Melo,Gabriel A. R.
For the first time, confirmed host records are reported for the monotypic Ericrocidini genus Aglaomelissa Snelling &amp;amp; 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...

Geographic distribution and spatial differentiation in the color pattern of abdominal stripes of the Neotropical stingless bee Melipona quadrifasciata (Hymenoptera: Apidae)
Provedor de dados: 103
Autores: Batalha-Filho,Henrique; Melo,Gabriel A. R.; Waldschmidt,Ana M.; Campos,Lucio A. O.; Fernandes-Salomão,Tânia M.
Melipona quadrifasciata Lepeletier, 1836, regionally known as "mandaçaia", has been traditionally divided in two distinct subspecies: M. quadrifasciata anthidioides and M. quadrifasciata quadrifasciata. The main difference between the subspecies refers to the yellow metasomal stripes which are continuous in M. q. quadrifasciata and discontinuous in M. q. anthidioides. This study investigated the geographic differentiation in the metasomal stripes and characterized the restriction sites in the mtDNA of both chromatic types. Specimens from 198 localities were examined, and the variation observed in the pattern of stripes was grouped into distinct classes. The distribution pattern found in the present work agrees with the previously reported pattern: M. q....

Higher-level bee classifications (Hymenoptera, Apoidea, Apidae sensu lato)
Provedor de dados: 104
Autores: Melo,Gabriel A. R.; Gonçalves,Rodrigo B.
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...

Provedor de dados: 104
Autores: Melo,Gabriel A. R.; Faria Jr,Luiz R. R.; Marchi,Paola; Carvalho,Claudio J. B. de.
Here we report for the first time data on parasitism of two species of Euglossa, E. intersecta Latreille, 1838 and E. anodorhynchi Nemésio, 2006, by conopid flies of the genus Physocephala Schiner, 1861. A parasitized adult male of E. intersecta was collected in Acre, northwestern Brazil,while parasitized adult females of E. anodorhynchi were obtained from trap-nests in São Paulo, southeastern Brazil. For both host species, the parasite-host association was confirmed by rearing the flies from parasitized adult bees. E. anodorhynchi was attacked by Physocephala bipunctata (Macquart, 1843) and E. intersecta by an unidentified species of Physocephala Schiner, 1861. Although our current knowledge is still incipient, parasitism by conopid flies can be...
