Lagenida (suborder Lagenina in Loeblich and Tappan 1988) is an emendation of the rotaliid superfamily Nodosariacea, removing it from the Rotaliina in the Treatise on Invertebrate Paleontology (Loeblich and Tappan, 1964) and combining it with the Robuloidacea, named by Reiss, 1963, to form a new order Lagenida.
Robuloidacea includes families previously included in the Fusulinida and found in either of the supefamilies Parathuramminacea and Endothyracea.
