Dimensions. d (d x D): 9 × 10.5 mm; septa: around 120; septa/mm (peripheral area): 8 ‒ 9/2; septa/mm (calicinal pit): 5 ‒ 6/1; d/D: 0.86.

Description. Cupolate corallum, nearly circular in outline; septa thin, nearly equal in thickness, straight to slightly wavy; calicinal pit small, elongate; calicinal groove parallel to calicinal pit might be present.

Type locality of species. Upper Maastrichtian of Iran ( Neyriz , Esfahan) .

Distribution. Upper Maastrichtian of Iran (Neyriz; Zagros Zone, southwestern Iran; this paper).

New material. FT1337–FT1338 (Zagros Zone, southwestern Iran).

Remarks. Te new material from Iran represents a rather more juvenile form. Corallum shape and dimensions of skeletal elements very closely correspond to the holotype of C. angiostoma (see Baron-Szabo, 2008).
