Eufriesea pulchra smith (Hymenoptera: Apidae: Euglossini): extended geographic distribution and filling gaps in Mato Grosso state, Brazil

This study was conducted in the Cotriguaçu district, situated on the bank of the Juruena River, in Mato Grosso state. The collects were carried out from August 22 to 25, 2007 with chemical baits to attract male orchid bees. The bees were captured on a daily basis, from 8 a.m. to 12 p.m. Of the 89 males captured three belonged to Eufriesea pulchra Smith. Before the present study, E.pulchra had been reported in the states of Pará, Amazonas, Amapá, (dubiously) São Paulo, and Maranhão. This occurrence extends its geographical distribution range by 900 to 2,000 km southwards in South America, as it is now recorded in the Amazon and Platina basins.

Occurrence of Eulaema (Apeulaema) pseudocingulata Oliveira (Hymenoptera: Apidae: Euglossini) in the Platina Basin, Mato Grosso State, Brazil

This study was conducted in the Chapada dos Guimarães National Park and in the Província Serrana of Mato Grosso state, from May 2003 to July 2005 and involved the use of chemical baits to attract male orchid bees. A total of 498 males were captured, of which 38 were Eulaema (Apeulaema) pseudocingulata Oliveira. Twenty-nine of these were collected in the national park and nine in the Província Serrana. E. pseudocingulata was reported as endemic to the Amazon Basin, however in the Platina Basin the species is sympatric to E. cingulata (Fabricius), a sibling species of similar morphology and color pattern but with a broader geographic distribution.

Em um estudo conduzido no Parque Nacional da Chapada dos Guimarães e na Província Serrana de Mato Grosso, iscas-odores foram utilizadas de maio de 2003 a julho de 2005 para atrair machos de Euglossini. Um total de 498 machos foi capturado, dos quais 38 eram machos de Eulaema (Apeulaema) pseudocingulata Oliveira. Foram capturados 29 machos no parque nacional e nove machos na Província Serrana. E. pseudocingulata foi recentemente descrita e, antes do presente trabalho, relatada como endêmica da Bacia Amazônica. Todavia, na Bacia Platina, ocorre em simpatria com E. cingulata (Fabricius), espécie similar na morfologia e no padrão de coloração, mas com ampla distribuição geográfica.
