New, hitherto unpublished miospore information from the Middle and Upper Devonian of the Parnaíba Basin, northeastern and north-central Brazil, has enabled refinement of the chitinozoan zonation recently proposed for that basin. To a large extent, Devonian miospore zones defined for the Amazonas Basin can be also recognized in the Parnaíba Basin and other Western Gondwanan basins. The miospore zones are discussed and compared to the coeval Southern Euramerican miospore zonation, the regional
