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.
