| This study had as objective to evaluate whether the pillaging activity by native bees influences floral abscission. Samples were collected in ten individuals of Bougainvillea spectabilis. In the period between May 4 and June 1st, 2009, 2,874 flowers were collected on the ground and 2,895 from the plants, with three-day intervals between each collection and a total of 10 repetitions in each plant. We measured the total of closed flowers, open flowers, robbed flowers, normal flowers, open robbed flowers and non-robber open flowers, in both soil and plant. For the statistical analysis, the T-test was used to see whether there was a difference between the averages obtained from the evaluated characteristics between the soil flowers and plant flowers.

| A new species of Xylocopa Latreille, 1802, and notes on Xylocopa transitoria Pérez and X. mordax Smith (Hymenoptera, Apoidea). Xylocopa (Neoxylocopa) orthogonaspis sp. nov. (Brazil, Amazonas) is described. It is a remarkable species from the Amazonian Region easily recognized by the strong and sharp right angle between upper and posterior portions of the scutellum; the wings are slightly brown with a brassy hue and a little vinaceous apex. Some notes to separate Xylocopa (N.) orthogonaspis sp. nov. from X. (N.) transitoria Pérez, 1901, and X. (N.) mordax Smith, 1874, are given. Xylocopa (N.) submordax Cockerell, 1935, on the other hand, is considered as a new synonym of X. (N.) transitoria Pérez, 1901. |
