Extra details from original publication
Range: This species was recorded only in the uppermost Valapertina Zone (Kossovian): this seems to be the last representative of the genus in the Paratethyan area; it is well known that in Paratethys after the Kosovian stage the marine facies is abruptly replaced by the brackish facies (Sarmatian stage) in which no marine fauna or flora survives.

Our specimens arc closely related to the specimen figured by Kennett & Srinivasan (1983, p. 86, Pl. 20, Fig. 1) as Orbulina suturalis from D.S.D.P., site 208, 18 cc (Globorotalia mayeri Zone), which roughly corresponds to the same stratigraphical level (NF2)
