Contribution to the Knowledge of Twenty Members of the Lagenid Benthic Foraminifera in the Southern Tethys

Abstract

The modern taxonomical consideration is used for twenty Lagenid benthic foraminiferal species which are belonging to eight genera from nine countries in the Southern Tethys: Chile, Argentina, Egypt, Tanzania, Jordan, Iraq, United Arab Emirates (UAE), Iran and Pakistan: Nodosaria catenula (Reuss) Iraq, Pyramidulina robinsoni (Futyan) Jordan, Tollmannia costata (d’Orbigny), Tollmannia fingeri Anan, sp. nov., Percultazonaria fragaria (Gümbel), Percultazonaria tuberculata (Plummer), Lenticuzonaria argentinica Anan, Lenticuzonaria misrensis Anan, Percultalina misrensis Anan, Hemirobulina comma (Roemer), Hemirobulina curvatura (Cushman), Hemirobulina humilis (Reuss), Hemirobulina nammalensis (Haque), Hemirobulina pachygaster Gümbel, Vaginulinopsis argentinica Anan, sp. nov., Vaginulinopsis deserti (Said & Kenawy), Vaginulinopsis emiratensis (Anan), Vaginulina boukharyi (Anan), Vaginulina chilensis Anan, sp. nov., and Ramulina shreifae Anan, sp. nov. Nine species of these assemblage were recorded from Egypt (about 45%), 3 species from Chile (about 15%), 2 species from Argentina (about 10%), and one species (about 5%) from each of Tanzania, Jordan, Iraq, UAE, Iran and Pakistan. Four species are believed here to be new: Tollmannia fingeri, Vaginulinopsis argentinica, Vaginulina chilensis and Ramulina shreifae.
