The Tubinellinae are a group of miliolid Foraminifera known from the Middle Eocene to the present, characterised by a test that is uniserial at maturity (Loeblich & Tappan 1964).

Characters (from Loeblich & Tappan 1964): Early milioline stage reduced; later portion uniserial, with rudimentary septa; aperture formed by open end of final chamber.
