DESCRIPTION
Solitary coral cylindrical to conical, elliptical in outline. Radial elements are straight or curved, free, compact, bicu- neiform costosepta with often rhopaloid inner edges. The septal apparatus is quite regular, organized in 3 distinct size orders. Lateral faces are smooth or finely granulated and there are some vestiges of a wavy mid-septal line. Endotheca made of numerous vesicular dissepiments distributed in all the interseptal space. No columella but a constricted, elongated fossa that defines a bilateral symmetry superimposed to the radial arrangement. No epitheca observed, possibly eroded.
Calicular diameter: 9 to 41 mm – Number of septa: 44 to 70 – Septal density: 3-4 per 2 mm.
SIMILARITIES AND DIFFERENCES
Differs from Coryphyllia regularis by the apparent lack of epitheca, a reduced average diameter, more bicuneiform septa and a more elongated calice defining a stronger bilateral symmetry. Coryphyllia capillaria n. sp. described below shows higher values of septal densities and number of septa and also a septal apparatus made of less bicuneiform septa in which it is more difficult to distinguish the different size orders of septa.
