| 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. |

| Collection data of Euglossinae males from Parque Estadual do Rio Doce (PERD) and Viçosa, both areas with remnants of Atlantic Rain Forest (Mata Atlântica) in Minas Gerais state, Brazil are presented. Comparisons made among three fragments with different sizes and states of disturbance from Viçosa showed differences in abundance of most common species and apparently, Eulaema nigrita Lepeletir, 1841 can be an useful indicator of disturbed sites. Some populations of euglossine bees seems to be restrict to a forest fragment, there being few or no flow of individuals or species of one fragment to another, even when they are only 1 km apart. 15 species of euglossines were sampled in PERD, and the most abundant was Eulaema cingulata (Fabricius, 1804). At Viçosa,... |

| 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... |

| A biologia floral e a polinização por abelhas Euglossini de uma Annonaceae é descrita pela primeira vez e as adaptações a esse modo de polinização são comparadas às de outras espécies da família, que é predominantemente polinizada por coleópteros. A espécie Unonopsis guatterioides foi estudada em dois fragmentos de mata de terra firme no município de Manaus (AM). As flores são protogínicas e permanecem abertas expondo os estigmas e estames durante a antese que ocorre entre dois dias. São visitadas por machos de Eulaema bombiformis (Euglossini) que coletam o odor o qual se assemelha ao de "capim cidreira" (Andropogum nardus L.). Visitas de abelhas Meliponidae e coleópteros Chrysomelidae também foram registradas. Unonopsis guatterioides apresenta dicogamia... |

| Community of Euglossini (Hymenoptera, Apidae) from the coastal sand dunes of Abaeté, Salvador, Bahia, Brazil. The Euglossini community structure was analyzed by attracting males with the scents eucalyptol, eugenol, vanillin, benzyl benzoate and methyl salicylate, and by netting bees on flowers. The samplings took place three times a month along one year from 6:00 a.m. to 6:00 p.m. The scent baits attracted 670 individuals belonging to seven species of three genus. The predominant species were Euglossa cordata (Linnaeus, 1758) (76.6%) and Eulaema nigrita Lepeletier, 1841 (21.8%). Euglossini males visited the scents along the whole year, being more abundant in May and in August. The most efficient fragrance was eucalyptol, attracting 624 individuals of five... |

| Males of Euglossa mandibularis Friese, 1899 can be categorized by (1) presence or (2) absence of scutellar tuft (a morphological feature of dense setae found in females' scutellum of the genera Euglossa Latreille, 1802 and Eulaema Lepeletier, 1841). A multivariate statistical analysis using six morphological measures (hindtibia length and width, head width, intertegular span, midbasitarsus length and scape length) show that males of the categories 1 and 2 were significantly different in relation to such measures. The width head, hindtibia length and scape length were the measures that most influenced the observed differences. Levene test suggest there is not effect of stabilizing selection on males without scutellar tuft. Since there is a fluctuation in... |

| Eufriesea violacea (Blanchard) is a very seasonal euglossine species, more frequently found in the southern and southeastern regions of Brazil. A number of studies have revealed large variations in the abundance of males of this species present in Atlantic Forest remnants throughout both regions. In this paper, we report variations in the abundance of E. violacea males sampled in several forest patches of different sizes (ranging from 10 to 580 ha), and we propose that this species is possibly sensitive to the reduction in size of forest remnants. Surveys were carried out in nine forest remnants of Atlantic rainforest located in northern Paraná State, southern Brazil. Male euglossine bees were collected with an entomological net when visiting scent-baits,... |

| Species composition, relative abundance, seasonal changes in the species abundance and scent association of male Euglossini collected in a semi-deciduous forest fragment in the north of the State of Paraná, southern Brazil, were recorded. Euglossine males were collected twice a month, for twelve months, from 8:00 am to 3:00 pm. The scents eucalyptol, eugenol, vanillin, methyl salicylate and benzyl acetate were used as baits. A total of 434 males distributed among 3 genera and 9 species were attracted to the chemical baits. Eufriesea violacea (Blanchard, 1840) (49.8%), Eulaema nigrita Lepeletier, 1841 (23.0%) and Euglossa pleosticta Dressler, 1982 (13.8%) were dominant in number of individuals. Among the non-dominant species, Euglossa fimbriata Rebêlo... |

| In the current literature, information is scarce on which part of the adult insect body is suitable for isolation of genomic DNA for genetic analysis based on DNA-markers. In this study, we evaluated RAPD profiles generated from total genomic DNA isolated from distinct body parts (head, legs, thorax + wings and abdomen) of 12 males of Euglossa pleosticta Dressler. From the total of bands analyzed, 9.0% did not show reproducibility. Percent variations of bands in each body segment were: 1.1% (head); 0.4% (legs); 0.8% (thorax/wings) and 6.7% (abdomen). The much higher variation (chi2one sample = 10.27; df = 1; P < 0.01) in the RAPD profiles obtained by using DNA isolated from abdomen of the euglossine males suggests that this body part of adult insects... |

| Foi analisada a floração, a frutificação e a biologia da polinização em duas espécies de Marantaceae: Ischnosiphon gracilis (Rudge) Koern. e Stromanthe porteana A. Gris. As observações foram realizadas em populações naturais no Parque Estadual Dois Irmãos (8º7'30" S e 34º52'30" W), um remanescente de Floresta Atlântica em Pernambuco. Nas duas espécies foi verificado padrão fenológico contínuo, com diferentes picos de floração e frutificação. As inflorescências em I. gracilis produziram 14,4 ± 3,4 flores e 1,3 ± 0,6 frutos, enquanto em S. porteana, produziram 125,4 ± 14,8 flores e 7,4 ± 4,9 frutos. Foram verificadas baixa razão pólen/óvulo e reduzida produção natural de frutos nas duas espécies. Em I. gracilis, a concentração de açúcares no néctar foi alta... |

| A communal dormitory of male orchid bees, Euglossa melanotricha Moure, was monitored over a one-year period, when they passed the night in the fronds of a Serpocaulon triseriale (Polypodiaceae) fern. The bees used the same fronds continuously, moving to neighboring fronds as senescence set in. As many as 49 males were observed together on any one night, clinging to the midribs on the abaxial surface of up to five fern blades with their mandibles. A number of males returned to the same site to pass the night continuously over a number of months, and were observed making physical contact with one another without provoking agonistic behavior. Males of E. melanotricha appeared to prefer sleeping at sites close to nests and potential sources of odoriferous... |

| Three nests of Euglossa (Glossura) annectans Dressier, 1982 were obtained from trap nests at Serra do Japi, Jundiai, São Paulo State, Brazil. The bees nested in bamboo cane (one nest) and in wooden-boxes (two nests). Solitary (two cases) and pleometrotic (one case) foundations were observed. Two nests were re-used once by two females working in each of them. Re-using females that shared the nests were of the same generation and each built, provisioned and oviposited in her own cells, characterizing a communal association. The brood development period was related to climatic conditions. Natural enemies included Anthrax oedipus oedipus Fabricius, 1805 (Bombyliidae), Coelioxys sp. (Megachilidae) and Melittobia sp. (Eulophidae). |
