*1948 Dictyoconella complanata n. gen., n. sp. – Henson, p. 25, plate 6, figs. 2-3, 16, pl. 10, fig. 14.

1998 Dictyoconella complanata Henson – Whittaker et al., pl. 47, figs. 4-6.

2021 Dictyoconella complanata Henson – Schlagintweit and Rashidi, p. 7, figs. 2a-b pars, 3-4 (with synonymy).

Remarks: A single specimen (~ 4 mm in diameter) in a slightly oblique section parallel to the plane of test compression. D. complanata has so far been reported from Maastrichtian strata; the occurrence in the Campanian of Greece extends its stratigraphic record and also the previously assumed palaeogeographic restriction to the Arabi- an Plate (see Schlagintweit and Rashidi, 2021).
