A new genus and species of foraminifera is described from the Maastrichtian of the Golkoy (Ordu) region of Turkey. It is named Sirelina orduensis n. gen., n. sp. The test of the genus has a microgranular calcereous structure and chevron canal systems are visible. In the early stage, chambers have a coiled milioline structure; however, they are trochospiral in the juvenile stage and uniserial in the adult stage. In the adult stage, lateral orbital chamber are developed. The aperture is cribrate in shape. It may easily be distinguished from the other similar genera by its test structure and coiling system.
