ABSTRACT The taxonomy, phylogeny and biostratigraphy of late Oligocene and early Miocene Globigerinoides and Trilobatus is reviewed. Trilobatus and Globigerinoides are two long-ranging genera appearing in the late Oligocene and early Miocene, respectively. They diversified within the range interval of Paragloborotalia kugleri and are still present in modern oceans as some of the most abundant mixed-layer dwelling groups. The distinctive characteristic of the genera is the presence of one to several supplementary apertures on the spiral side. Globigerinoides species possess a ruber/sacculifer -type wall, Trilobatus possesses a sacculifer-type wall texture. The ruber -type wall texture probably appeared in the late Miocene with the appearance of G. ruber s.s. The following species of Globigerinoides are recognized as valid: G. altiaperturus Bolli, G. bollii Blow, G. italicus Mosna and Vercesi, G. joli Spezzaferri n. sp., G. neoparawoodi Spezzaferri n. sp., G. obliquas Bolli, and G. subquadratus Brönnimann. The following species of Trilobatus are recognized as valid: T. altospiralis Spezzaferri n. sp., T. immaturus (LeRoy), T. praeimmaturus (Brönnimann and Resig), T. primordius (Blow and Banner), T. quadrilobatus (d’Orbigny), T. subsacculifer (Cita, Premoli Silva, and Rossi) and T. trilobus (Reuss).
