This study deals with taxonomic consideration of one genus Marginulinoides and thirty six Arabian benthic and planktic foraminiferal species of Anan, which belongs to twenty six four genera from Saudi Arabia (SA), Qatar, United Arab Emirates (UAE) and Oman. The Arabian fauna made it possible to correlate them with those previously identified species in the coeval stratigraphic sequence in different Tethyan localities: Morocco, Egypt, UAE, and India. Twelve recorded species belong to Suborder Globigerinina, 11 to Lagenina, 7 to Textulariina, and 6 to Rotaliina. One genus and 26 species of them (~72%) are recorded from UAE, 8 species (~22%) from Oman, and one species (~3%) from each of Saudi Arabia and Qatar. Two of the recorded species are believed here to be new: Tollmannia qatarica and Acarinina saudica.
