Family Pseudoaulophacidae (Radiolaria) from the Upper Cretaceous (Coniacian-Maastrichtian) of Cyprus

Well-preserved Late Cretaceous (Coniacian-Early Maastrichtian) radiolarians from the Perapedhi, Moni and Kannaviou formations (Cyprus) were investigated. Abundant and diverse members of the family Pseudoaulophacidae are recognized and studied. The description of the species Pseudoaulophacus lenticulatus and Pseudoaulophacus pargueraensis are emended. A new radiolarian genus Pseudoalievium with two new species (P. parekklisiense and P. inflatum), one new species of the genus Alievium (A. mangaleniense) and one new species of the genus Pseudoaulophacus (P. decoratus) are described. Geographical and stratigraphical ranges of the studied taxa of the family Pseudoaulophacidae are more exactly defined. Several rare species of this family are traced in the Tethyan Realm.
