NEW SPECIES "MIOGYPSINOIDES AKCADAGENSIS N. SP." FROM A CHATTIAN DEPOSIT FROM AKCADAG REGION, MALATYA, TURKEY
This study aims to define the new miogypsinid species" Miogypsinoides akcadagensis n. sp." from the Late Oligocene of the Akcadag region located in western Malatya, Turkey. The new species differs from the Chattian Miogypsinoides by less spiral chambers (X value). M. akcadagensis is characterized by 8-10 trochospiral chambers in its early rotaliid stage, while M. complanatus (Schlumberger) has spiral chambers more than 17 and M. bermudezi Drooger, M. borodinensis Hanzawa and M. bantamensis Tan have 12-14 spiral chambers.
