DESCRIPTION
Solitary cylindroconical corallum sometimes showing piled up enlarged rings corresponding to starts and stops alternation in growth. Elliptical calice with flattened calicular platform showing a slightly deepened axial fossa. Radial elements compact, free, joining only in depth at the center, exsert, slightly bicuneiform to attenuated, generally straight costosepta, with lateral S1 curved. Distal edge festooned, lateral faces smooth. Distal inner edge with large well detached teeth. Radial hexameral symmetry. Bilateral symmetry marked by the elongated fossa and the curvature of lateral S1. Endotheca made of extended tabular dissepiments climbing along the wall. No synapticule. An epicostal epitheca s.l. covers the external part of the corallum.
Calicular diameter: 20 to 40 mm – Number of septa: approximately 60 to 70 – Septal density: 2-3 per 2 mm.
SIMILARITIES AND DIFFERENCES
Differs from Epismiliopsis liasicus ( Fromentel & Ferry, 1865) by the absence of detached septal spines at the inner edge of septa, an elliptical calice and a lower number of radial elements. It differs also from E. eudesi ( Fromentel & Ferry, 1865) by its higher diameter and number of septa. However we cannot exclude that the holotype of E. eudesi (the only specimen known) could be a young stage of the same species.
