The present study deals with the modern taxonomical consideration of the sixteen Brazilian Cretaceous smaller benthic foraminiferal species belonging to thirteen genera and represent good example of the Southern Tethyan benthic foraminiferal species. Ten out of these species are treated here as new: Gaudryina brazilica, Textularia brazilica, Ammobaculoides brazilica, Hemirobulina brazilica, Marginulina brazilica, Citharina brazilica, Planularia brazilica, Guttulina brazilica, Bolivina brazilica and Valvulineria brazilensis. The other six species have new generic name according to the modern taxonomy: Laevidentalina mirandai, Lenticubella benderi, Coryphostoma incrassata, Valvulineria calumbiensis, V. garai, and V. leonardosi. The Brazilian Southern Tethyan taxa indicate an open marine environment, which represents outer neritic environmental conditions of the identified species mainly represent warm stratigraphic interval water neritic environment (~200m). These wide paleogeographic distributions proved that the ancestral Tethys was connected with the ancestral Atlantic and Indian Oceans via Mediterranean Sea.
