A new species of Eufriesea Cockerell (Hymenoptera, Apidae, Euglossina) from northeastern Brazil Rev. Bras. entomol.
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.

Daily activity patterns of visits by males of four species of Eulaema (Apidae: Euglossina) to odor baits in a tropical forest fragment in Bahia, Brasil Rev. Bras. Zool.
Melo,Pedro N.; Gimenes,Miriam; Oliveira Neto,Antonio.
Several studies have been conducted with bees of the subtribe Euglossina using odor baits as attractants. The objective of this study was to analyze the daily activity pattern of visits by males of four species of Eulaema - Eulaema nigrita Lepeletier, 1841, Eulaema flavescens (Friese, 1899), Eulaema cingulata (Fabricius, 1804) and Eulaema bombiformis (Packard, 1869) - to vanillin and benzyl acetate baits, and their relationship with climatic and environmental factors throughout the day in different months of the year in a tropical forest fragment in Bahia. Eulaema nigrita was the most frequent species on vanillin baits and E. flavescens was the most frequent species on benzyl acetate baits. The highest frequency of visits was observed in February and...

Discovery of Euglossa (Euglossa) cognata Moure (Apidae: Euglossini) in the Platina Basin, Mato Grosso state, Brazil Biota Neotropica
Anjos-Silva,Evandson José dos.
By attracting male orchid bees with eight chemical baits in the gallery forest of the Parque Nacional da Chapada dos Guimarães, southern Mato Grosso state, Brazil, I found several males belongs to all Euglossini bee genera. Male euglosine bees were collected monthly using an entomological net as they arrived at the baits. From September 2003 to July 2005, the baits were applied to absorbent paper pads from 8:00 AM to 4:00 PM. From 24 collections, a total of 264 males were captured, spread throughout the five genera of the tribe and belonging to 30 valid species. Of all the males collected, only one was Euglossa cognata Moure, reported to occur from Costa Rica to southern Brazil, and herein recorded to the Platina Basin for the first time. The results...

Diversity of the euglossine bee community (Hymenoptera, Apidae) of an Atlantic Forest remnant in southeastern Brazil Rev. Bras. entomol.
Silveira,Guilherme do Carmo; Nascimento,Anderson Machado; Sofia,Silvia Helena; Augusto,Solange Cristina.
Diversity of the euglossine bee community (Hymenoptera, Apidae) of an Atlantic Forest remnant in southeastern Brazil. Euglossine bees, attracted to scent baits of cineole, eugenol and vanillin, were collected with entomological nets, from December 1998 to November 1999. Samplings were carried out once a month simultaneously by two collectors positioned in two different sites in an Atlantic Forest remnant in northeastern São Paulo state, Brazil. A total of 859 male euglossine bees, belonging to 13 species and four Euglossini genera were collected. Of the total sample, 506 (12 species) males were captured at site A and 353 (10 species) were collected at site B.In both sites, Euglossa pleosticta Dressler, 1982 was the most abundant species (45.79%), followed...

Do euglossine males (Apidae, Euglossini) leave tropical rainforest to collect fragrances in sugarcane monocultures? Zoologia
Milet-Pinheiro,Paulo; Schlindwein,Clemens.
Euglossine bees are known to be long-distance pollinators in tropical rainforests. But there is controversy concerning to the flight ranges of these bees between forest fragments. In an isolated fragment of Atlantic Rainforest in Pernambuco, NE Brazil, surrounded by sugarcane monocultures, it was examined if euglossine males leave closed rainforest to collect fragrances. In a straight-line transect leading from forest into a sugarcane plantation, euglossine males were simultaneously captured by scent baits at seven distinct points: inside the forest, forest edge, outside the forest in the sugarcane fields at distances of 10 m, 50 m, 100 m, 250 m and 500 m from the forest edge. A total of 945 euglossine bees of 16 species were recorded. The results...

Euglossine bee communities in small forest fragments of the Atlantic Forest, Rio de Janeiro state, southeastern Brazil (Hymenoptera, Apidae) Rev. Bras. entomol.
Aguiar,Willian Moura de; Gaglianone,Maria Cristina.
Euglossine bee communities in small forest fragments of the Atlantic Forest, Rio de Janeiro state, southeastern Brazil (Hymenoptera, Apidae). Euglossine bees are important pollinators in forests and agricultural areas. Although the structure of their communities is critically affected by anthropogenic disturbances, little is known about these bees in small forest fragments. The objectives of this study were to analyze the composition, abundance, and diversity of euglossine bee species in nine small fragments of different phytophysiognomies of the Atlantic Forest in southeastern Brazil, and to identify the environmental variables that may be related to the species composition of these communities. Males were sampled quarterly from May 2007 to May 2009 with...

Euglossine bees (Hymenoptera, Apidae) in a remnant of Atlantic Forest in Paraná State, Brazil Iheringia, Sér. Zool.
Sofia,Silvia H.; Santos,Aline M. dos; Silva,Carlos R. M. da.
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...

Observations on fragrance collection behaviour of euglossine bees (Hymenoptera, Apidae) Rev. Bras. entomol.
Holland,Peter W.H..
Male bees of the tribe Euglossini collect volatile chemicals secreted by orchids using dense patches of hair on the front tarsi. After collecting chemicals, the bee hovers while transferring these fragrances to invaginations on the hind tibiae. The fragrance collection and hovering behaviours are repeated multiple times. Here I report preliminary field observations on the length of fragrance collection and hovering phases in bees of the Eulaema meriana (Oliver, 1789) mimicry complex visiting the orchid Catasetum discolor in Kavanayén,Venezuela. I observed that in extended visits with many cycles of fragrance collection and hovering, the length of each collection phase gradually increased, while the length of hovering phase was static. This suggests either...

Orchid bees (Hymenoptera: Apidae) in the coastal forests of southern Brazil: diversity, efficiency of sampling methods and comparison with other Atlantic forest surveys Pap. Avulsos de Zool. (São Paulo)
Mattozo,Vanessa C.; Faria,Luiz R.R.; Melo,Gabriel A.R..
Surveys of orchid bees at the Brazilian Atlantic forest have been restricted to a few regions, making difficult to understand latitudinal patterns of distribution and diversity of these bees. For this reason we sampled the euglossine fauna at Atlantic forest areas at the coastal region of São Paulo (Sete Barras, Faz. Morro do Capim: SP3) and state of Paraná (Antonina, Reserva Natural do Rio Cachoeira: PR3), in southern Brazil. In PR3, we also evaluated the efficiency of collecting methods for sampling the fauna, comparing bait traps with direct collecting using entomological nets on fragrance baits. The diversity and abundance of bees was very low: we caught only 39 males of eight species in SP3 (Euglossa iopoecila, Euglossa roderici, Eulaema nigrita,...

Scent-robbing and fighting among male orchid bees, Eulaema (Apeulaema) nigrita Lepeletier, 1841 (Hymenoptera: Apidae: Euglossini) Biota Neotropica
Carvalho Filho,Fernando da Silva.
Male Neotropical orchid bees (Euglossini) collect volatile chemicals from floral and non-floral sources and store then in specialized hind tibial structures. The ultimate causes of euglossine fragrance collection remain a mystery. Recent evidence suggests that odoriferous substances play a role in euglossine courtship and serve as indicator of male genetic quality. Males of Eulaema nigrita were observed robbing scents from the detached hind legs of a conspecific male E. nigrita in Belém, Brazil. The hind leg seemed to have been detached during fights between males, since one male was missing a hind leg where the observation was made. This behavior appears to be common among males of E. nigrita since more than one case was observed on the same day. The...

Faria Jr.,Luiz R. R.; Melo,Gabriel A. R..
The species of Euglossa (Glossura) occuring in the Brazilian Atlantic forest were revised and an identification key to males and females is provided. The status of Euglossa annectans Dressler and E. stellfeldi Moure is reevaluated and the latter species is transferred from E. (Glossura) to E. (Glossurella). Here we also synonymize E. carinilabris Dressler under E. stellfeldi. Taxonomic notes are provided and relevant morphological features are illustred. Latitudinal color variation along the Brazilian Atlantic forest, found in two of the species studied here, is also presented and discussed.
