“…O mesmo padrão pode ser encontrado na análise da composição das espécies amostradas nas áreas de transição do estado de Mato Grosso (ver Anjos- Silva, 2006 Moure et al, 2007;Nemésio & Silveira, 2007b;Nemésio, 2009). Deve ser ressaltado ainda que as matas de galeria, como é o caso da localidade MTCH, aparentemente desempenham um papel importante no trânsito de elementos amazônicos e atlânticos (Anjos- Silva, 2006;Anjos-Silva et al, 2006;Carvalho et al, 2006;Nemésio et al, 2007;Anjos-Silva, 2008;Moura & Schlindwein, 2009;Anjos-Silva, 2010;ver também Nemésio & Faria, 2004).…”

Padrões espaciais na distribuição de abelhas Euglossina (Hymenoptera, Apidae) da região Neotropical

Abelhas das orquídeas (Apini, Euglossina) apresentam distribuição principalmente Neotropical, com cerca de 200 espécies e cinco gêneros descritos. Muitos levantamentos locais de fauna estão disponíveis na literatura, mas estudos comparativos sobre a composição e distribuição dos Euglossina são ainda escassos. O objetivo deste estudo é analisar os dados disponíveis de 29 assembleias a fim de entender os padrões gerais de distribuição espacial nas áreas amostradas ao longo do Neotrópico. Métodos de ordenação (DCA e NMDS) foram utilizados para descrever os agrupamentos de assembleias de acordo com as ocorrências de abelhas das orquídeas. As localidades de florestas da América Central e da Amazônia formaram grupos coesos em ambas as análises, enquanto as localidades de Mata Atlântica ficaram mais dispersas nos gráficos. Localidades na margem leste da Amazônia aparecem como áreas de transição características entre esta sub-região e a Mata Atlântica. As análises de variância entre o primeiro eixo da DCA e variáveis selecionadas apresentaram valores significantes quanto à influência dos gradientes de latitude, longitude e precipitação, bem como das sub-regiões biogeográficas nos agrupamentos das assembleias. O padrão geral encontrado é congruente com os padrões biogeográficos previamente propostos para a região Neotropical. Os resultados do DCA auxiliam ainda a identificar, de forma independente, os elementos das faunas de cada uma das formações vegetais estudadas.

“…In this vast tropical savanna biome, even with the continuous deforestation process, few works have been made on the euglossine bee fauna (Rebêlo & Cabral 1997, Nemésio & Faria 2004, Carvalho et al 2006, Alvarenga et al 2007, Anjos-Silva 2007, 2010. So, the objectives of this work, was to study the species composition, abundance and the seasonal and hourly distribution of euglossine bees in a Gallery Forest in the Brazilian Cerrado.…”

The orchid bees are a very important group of pollinators distributed in the Neotropics. Although a lot of studies concerning male euglossine bees have been done in this region, few works have so far been carried out in the Cerrado biome. This manuscript has the main objective to present the orchid bee community from a Gallery Forest in the Northeastern Brazilian Cerrado landscape, taking account the species composition, abundance, seasonality and hourly distribution. Male euglossine bees were collected monthly from October 2007 to May 2009, in the Reserva Florestal da Itamacaoca belonging to the Companhia de Água e Esgoto do Maranhão, in Chapadinha municipality, Maranhão State. The scents eucalyptol, eugenol and vanillin were utilized, between 07:00 and 17:00hr, to attract the euglossine males. Cotton balls were dampened with the scents and suspended by a string on tree branches 1.5m above soil level, set 8m from one another. The specimens were captured with entomological nets, killed with ethyl acetate and transported to the laboratory to be identified. A total of 158 individuals and 14 species of bees were recorded. The genus Eulaema was the most representative group of euglossine bees in relation to the total number of the sampled individuals, accounting for 50.6% of bees followed by Euglossa (26.6%), Eufriesea (15.2%) and Exaerete (7.6%). The most frequent species were Eulaema nigrita (27.8%), Eulaema cingulata (19%) and Euglossa cordata (18.3%). Many species typical of forested environments were found in samples, like Euglossa avicula, Euglossa violaceifrons and Eulaema meriana, emphasizing the role played by the Gallery Forests as bridge sites to connect the two great biomes of Amazonia and Atlantic Forest. The occurrence of Exaerete guaykuru represents the second record of this species for the Neotropical region, and both records coming from the Gallery Forest zones. The male euglossine bees were sampled mainly in the dry season, where 62.5% of the individuals were collected in that period. Eufriesea species appeared at the baits only in the wet season. The hourly frequency of bees at scent baits showed a clear preference for the morning period, where 87.9% visited the baits from 07:00 to 12:00hr. The euglossine bee fauna found in the Northeastern Maranhão Cerrado is represented chiefly by species of large geographic distribution and by some forest bee species, where their occurrence is maybe related to to the environmental conditions supported by the

A checklist of Euglossini in Ecuador is given, including all currently described, valid species collected until 2018. The list has been assembled from museum records, fieldwork cited herein, and literature. The former species lists are nearly doubled here, with 1 Aglae, 23 Eufriesea, 68 Euglossa, 18 Eulaema, and 5 Exaerete, 115 in total with >50 new records for the country. Distribution and collection data are included, and some doubtful species are discussed. The Amazon region is the most species rich area but not necessarily a natural pattern, perhaps due to uneven sampling effort across the country. Southern Ecuador is relatively little sampled.
