Type Species

Ellipsocoenia regularis d’Orbigny, 1850: 92; Original Designation d’Orbigny, 1850: 92

Type Specimen: Syntype; Cn 47518 and 47523-24; Verified; Unknown

Type locality: Hauterivian of France (Fontenoy).

Classification

Diagnosis

Colonial, massive, plocoid to subcerioid. Gemmation intracalicinal. Calices circular, irregularly elliptical, or polygonal in outline, monocentric. Costosepta subcompact with large pores, nonconfluent to subconfluent, rarely confluent. Septal flanks have small rounded granulae and small pennulae. Columella trabecular, spongy-papillose. Wall synapticulothecal. Endothecal and exothecal dissepiments numerous.

Remarks

Wells (1956) stated that the genus Ellipsocoenia represented a younger synonym of the genus Favia Oken. However, due to fundamental differences in e.g. the septal development (faviid septa in Favia; fungiid septa in Ellipsocoenia) the two taxa should be grouped in different suborders.
