In this study, the genus Alveolina D’ Orbigny, 1826 and its Alveolina (Alveolina) D’ Orbigny, 1826 and Alveolina (Glomalveolina) Hottinger, 1960 subgenera were re-examined and identified. Systematics of the subgenera Alveolina (Alveolina)=Alv. (Alv.) and Alveolina (Glomalveolina)=Alv.(Glomalv.) have also been reviewed and revised. Alv. (Glomalv.) is considered as a subgenus, not a genus (?). Because, all the generic features of microspheric generations (fB) of these two subgenera are identical. Thus, Alveolina D’ Orbigny, 1826 and Glomalveolina Hottinger, 1960 cannot be used as if they were two different genera (?). Otherwise Glomalveolina would be the synonym of Alveolina in “Systematic Paleontology” chapter. Therefore, Alv. (Alv.) and Alv. (Glomalv.) are both subgenusses, and the structural difference between these subgenera is observed seen in their megalospheric generations (fA). Besides, description of the genus (?) Glomalveolina has never been made in any of the studies in which Glomalveolina is referred as genus (?). However, the subgenus Alv. (Glomalv.) has incorrectly been used by many authors as “genus (?) Glomalveolina Hottinger, 1960 or 1962”.
