The "avatars" of Triloculina laevigata Orbigny , 1826, generic and specific attribution

[摘要] The purpose of this study is to clarify the problem posed by Triloculina laevigata Orbigny , 1826, nom. nud ., described and figured by Fornasini in 1905. An other species, also called Triloculina laevigata was created by Bornemann in 1855 and Orbigny 's specific name became invalid. This invalidity was only recently assessed and numerous authors still use the original assignation. Consequently, it seems necessary to erect a new name. After listing the various names, revising the subgenus and genera attributed to Triloculina laevigata , and comparing fossil and recent specimens, the name: Affinetrina alcidi Lévy et al. , 1992a, is confirmed.
