Initially described by Bakalova (1971) as Cylindroporella elitzae , this dasycladalean alga was subsequently attributed to the genus Montiella by Radoićič (1980). Bucur (1993) transferred it to the new genus Bakalovaella by highlighting some differences between the Cenozoic species of Montiella ( M. munieri and M. macropora ) and the Lower Cretaceous alga originally assigned to the genus Cylindroporella . However, numerous paleoalgologists avoided its attribution to the genus Bakalovaella and preferred to assign it to Montiella . Subsequently, some authors (Taherpour Khalil Abad et al., 2010; Bucur, 2011 ) questioned once more the attribution of the species elitzae to the genus Montiella , and recently Granier & Bucur (2019) reinstated the genus Bakalovaella based on the species Bakalovaella deloffrei Granier & Bucur , and revalidated the combination Bakalovaella elitzae ( Bucur, 1993 ) .
