Abstract
Two new species of the genus Rediviva from South Africa are described to facilitate further research on this iconic group of oil-collecting bees: R. steineri sp. nov. ♀ and Rediviva whiteheadi sp. nov. ♀♂. Notomelitta tropicalis Cockerell 1934 syn. nov., that was erroneously transferred to the genus Rediviva, is recognized as a new junior synonym of Andrena africana Friese 1909.
