Praesphaerammina, a new genus of Cenozoic deep-water agglutinated foraminifera from the Carpathian flysch deposits.
The genus Praesphaerammina Kaminski and Filipcscu is newly described based on a revision of the type species Cystammina subgaleata Vasicek 1947. The genus differs from the Holocene genus Sphaerammina Cushman 1910 emend. Loeblich and Tappan 1964, in possessing a less embracing final chamber and in its interio-areal to areal aperture that lacks any tooth. The definition of the subfamily Sphaeramminae is accordingly emended as well. The genus is common in the Eocene of the Carpathian flysch deposits, but the type species Praesphaerammina subgaleata (Vasicek 1947) is also observed in the Caribbean region and West Africa, where it ranges into the Miocene.
