Abstract
The so called races of Drosophila paulistorum from South America are so deeply isolated ethologically that although still partially bridged by gene flow through hybridization, they should be considered as 6 separate sibling species just as the willistoni group to which D. paulistorum itself belongs. The present article emphasizes the way in which isolation is implemented.
