*2016 Accordiella? tarburensis n. sp. – Schlagintweit and Rashidi, p. 54, fig. 5a pars, 6–7, 8 pars (late Maastrichtian Tarbur Formation of Iran).
2018 Dukhania? cherchii n. sp. – Luger, p. 88, pl. 13, 6– 7, non 9 (= Gyroconulina columellifera ), 10-11 (late Maastrichtian Auradu Formation of Somalia).
Remarks: From the lower Auradu Formation, Luger (2018) established a new species as Dukhania? cherchii ( Fig. 3b View Fig ), that is considered a junior synonym of Accordiella? tarburensis ( Fig. 3a View Fig ). The maximum test height is up to 1.8 mm for the Somali, and up to 1.4 mm for the Iranian specimens. In both cases, the generic identity of the described species was indicated with some doubts ( Accordiella Farinacci , family Pfenderinidae : triserial, with endoskeletal plates and pillars; Dukhania Henson ,
family Chrysalidinidae : triserial becoming biserial, with endokeletal pillars, see Loeblich and Tappan 1988). Because of its marginally strongly overlapping chambers, and the extensive endoskeleton consisting of numerous pillars, Dukhania indeed seems to be closer to the Maastrichtian forms than Accordiella . For the moment being the name of the validly described taxon Accordiella? tarburensis is maintained. Last but not least, some axial sections of Gyroconulina columellifera Schroeder & Darmoian (see also below) show similarities ( Fig. 3d View Fig ). The marginal part of the chambers in the latter however displays subdivisions (exoskeleton).
