Abstract
Three new species of Alpaida O. Pickard-Cambridge, 1889 are described from the Brazilian Amazon region: Alpaida tukano sp. nov., A. kayapo sp. nov. and A. tupinamba sp. nov. Alpaida murtinho Levi, 1988 is newly synonymized with A. guimaraes Levi, 1988 and the male originally associated with A. guimaraes is redescribed as A. tupinamba sp. nov. The true male of A. guimaraes is redescribed, and the male of Aculepeira apa Levi, 1991 is described for the first time.
