摘要
The study of the Upper Cretaceous beds of southern Cyprus (Tethyan Superrealm) revealed rich radiolarian assemblages, including six-eight-rayed stauraxonic morphotypes, which rarely occur in the Mesozoic. The diagnosis of the genus Multastrum Vishnevskaya, 1991 is emended and four new species, Multastrum cypricum sp. nov., M. mangaleniense sp. nov., M. robustum sp. nov., and M. ? perapediense sp. nov., are described. The description of M. regale Vishnevskaya is emended. It is established that the genus Multastrum existed in the Coniacian-Campanian in both high and low latitude regions.
