Remarks : In his important monograph on Mesozoic- Cenozoic Larger Benthic Foraminifera from the area of the Middle East-South-Western Asia, Henson (1948) erected the genus Dictyconella for more or less "compressed-conical" dictyoconids including the two species D. complanata and D. minima . Both are however structurally completely different and cannot be assigned to the same genus (see Schlagintweit et al., 2016b ). A revision is currently under preparation. The type-species D. complanata was described from Maastrichtian carbonates of the Simsima Formation of Dukhan No. 1 well of Qatar . Henson (1948 , p. 24–25) noted the presence of a “zone with undivided chamber space” (or marginal ridge) between the marginal (with exoskeleton) and central zones (with endoskeleton; see also Hottinger, 2006 , p. 22) as described also from Dictyoconus Blanckenhorn by Davies (1938: marginal trough, see Fig. 4 d-e). There is reference that indicate the presence of D. complanata in the Garzan Formation of SE Turkey ( Çoruh et al., 1997 ), but real evidence is lacking so far.
