Remarks: Rare sections, not allowing a detailed description have been observed in the orbitolinid assemblage of Klokova Mountain. The species has a wide palaeogeographic distribution from Spain, Slovenia, Croatia, Greece, to India (see synonymy). In the original description, Calveziconus has been compared with the genera Orbitolinopsis Henson , Neorbitolinopsis Schroeder , and Abrardia Neumann & Damotte. Instead , striking structural matches with the Lower Aptian Iraqia Henson can be stated. These comprise the medium-high conical test, a simple, slightly eccentric embryo, a marginal zone with several beams and one rafter, and a reticulate central zone. From the Maastrichtian Simsima Formation of Qatar, Whittaker et al. (1998) reported “ Calveziconus ” sp. nov. showing a complex marginal zone (with up to four orders of rafters, pl. 42, fig. 3 therein) and pillars in the central zone (pl. 42, figs. 4-5 therein); this form is different from Calveziconus Caus & Cornella. More sections are needed for a better characterization of the Middle East form.
