Abstract
The new orbitolinid foraminifer Campanellula herishtensis n. sp. is described from the upper Aptian (Gargasian) of the Yazd Block, Central Iran. Campanellula herishtensis n. sp. occurs within a small interval of the Herisht section near Ardakan, displaying more or less uniform microfacies types (foraminiferal wackestones/packstones). The Iranian form differs from Campanellula capuensis De Castro (upper Hauterivian – lower Barremian of Italy, and Algeria), the only species described of the genus so far, in size and morphology (shape, apical angle). The generic assignment of the new taxon is discussed including also the genus Orbitolinopsis Henson. The suprageneric placement of Campanellula within the Orbitolinidae according to current classifications (but contrasting the original description) still remains doubtful.
