This study deals with a review of two new Paleogene benthic genera: Ornatodella Anan (2023) from Pakistan and Marginulinoides Anan (2024) from the United Arab Emirates (UAE), as well as one hundred and thirty-two Campanian-Paleogene and Recent benthic and planktic foraminiferal species were erected by the present author from twelve localities in South Asia: 18 species from Turkey (13.6%), 2 Palestine, 3 Jordan, 1 Saudi Arabia (SA), 10 Yaman (~7.6%), 8 Oman (~6%), 29 UAE (~22%), 1 Qatar, 11 Iraq (-8%), 37 Iran (~28%),15 Pakistan (-11%), and 2 species from India. Six species of the assemblage are believed here as new: Percultazonaria iranica, Percultazonaria iranensis, Lagena iranica, Aragonia iranica and Catapsydrax iranica and Subbotina iranica. 39 species of the assemblage belong to Suborder Textulariina (-30%), 8 Miliolina (-6%), 29 Lagenina (-22%), 36 Rotaliina (-27%) and 20 Globigerinina (~15%). Twenty-two of the recorded species present an evolutionary foraminiferal lineage: (1) Gaudryina acuta G. pyramidata G. limbata lineage, (2) Pseudoclavulina iranensis P. iranica, (3) Textularia haquei T. farafraensis, (4) Laevidentalina ameeri L. hudae L. salimi, (5) Ramulina pseudoaculeata R. futyani, (6) Ramulina ornata → R. salahii, (7) Stilostomella impensia S. turkiana, (8) Ellipsoglandulina turkiana E. arafati, (9) Planulina mellahensis → P. turkiana, (10) Cibicidoides nekhlianus C. turkiana, (11) Cibicides schwageri Cibicides turkiana, (12) Nuttallides turkiana N. turkiana, (13) Nonion havanense N. turkiana, (14) Oridorsalis umbonatus → 0. turkiana, (15) Osangularia turkiana 0. plummerae, (16) Anomalinoides turkiana A. zitteli, (17) Valvulineria iraqensis V. ranikotensis, (18) Ornatanomalina geei O. pakistanica, (19) Moruzovella lensiformis M. arabica M. crater M. aragonensis M. caucasica, (20) M. crater M. hafitensis M. caucasica, (21) Turborotalia cerroazulensis → T. semicunialensis T. cocoaensis T. cunialensis lineage.

This study has focused on the systematic paleontology are presented with more emphasis on their modern nomenclatural aspects of 30 benthic and planktic foraminiferal species belonging to 16 genera, were identified from four countries in the southwestern part of Asia (Palestine, Jordan, Iraq and Iran). 15 species of them (~50%) are recorded from the Ypresian-Lutetian of Iran, 10 species (~33%) from the Campanian-Maastrichtian of Iraq, 3 species (~10%) from the Danian-Lutetian of Jordan, only 2 species (~7%) from Maastrichtian of Palestine. Eighteen species of them are belonging to the Suborder Textulariina, 5 to Lagenina, 3 species to Rotaliina, and 4 to Globigerinina. Three species of them are believed here as new: Pseudoclavulina iraqensis, Ramulina irregularis and Ramulina radiata. Two benthic foraminiferal lineages are presented: Verneuilina lineage (Verneuilina iraqensis V. jordanica> V. luxorensis lineage), which explained also the evolutionary phenomena “Proterogenesis”, and Pseudoclavulina lineage (Pseudoclavulina, iraqensis > P. futyani > P. iranica lineage).
