Checklist of orchid bees (hymenoptera: Apidae) of "Lago do Silêncio" area, Boca do Acre, Amazonas, Brazil

Abstract

This study presents a list of euglossine-bee species collected in the Lago do Silêncio region, municipality of Boca do Acre, in the Brazilian state of Amazonas, southwestern Amazonia. Euglossine males were attracted to odoriferous baits on December 3 and 4, 2004. A total of 234 individuals belonging to four genera and 25 species were collected. Despite the small sampling effort, the local euglossine fauna is abundant and rich, when compared to those of other areas in the Brazilian Amazonia where higher sampling efforts were performed. Therefore, further studies in the region can be important for improving our knowledge of the bees in the Amazon region. © 2011 Check List and Authors.
