Lobophyllia flabellum Michelin p. 92 (1843) pl. 18 fig. 1 (1845); Subsequent Designation Vaughan and Wells 1843, p. 222 (despite they cite ME and H 1850)
Type Specimen: Syntype; MNHN A30299; Verified; Dry Preserved
Type Locality: Oxfordian (Upper Jurassic) from St Mihiel (France)
Beauvais (1964, p. 190) designated a neotype (MNHN M 00275) but possible syntypes from the Moreau collection were recently recovered. All of them are presently identified as Rhipidogyra. A decision of ICZN is necessary to fix the status of the type material.
Solitary flabelloid Rhipidogyrid corallum
Solitary flabelloid corallum with strong costae emerging from a thick granular tectura. Radial elements compact free strongly unequal in thickness. Apophysal septa potentially present. Distal edge smooth, inner edge with flabelloid auriculae, lateral faces with irregularly distributed granules, no palis. Microstructure rhipidogyrid. Bilateral symmetry highly expressed by the elongation of the calyx. Endotheca of vesicular dissepiments, columella lamellar, no synapticulae. Paraseptothecal wall.
Among Rhipidogyridae, Rhipidogyra can be confused with Fromentelligyra, which is colonial. It can be also confused with a broken part of the colonial Phytogyra. Codonosmilia is not flabelloid.
