TYPE LOCALITY. — Jebel Bou Dahar , Morocco . STUDIED SAMPLES. — Two specimens : holotype MNHN .F.R11623; CPUN Gu 1005E2. GEOGRAPHIC AND STRATIGRAPHIC RANGES. — Pliensbachian of Jebel Bou Dahar and Guigou Plateau , Morocco . DESCRIPTION Phaceloid colony with cylindrical corallites multiplying by extracalicular budding. Radial elements are wavy, compact costosepta apparently free and organized in two distinct size-orders. External lateral faces of the corallites are ornamented with vertical striation made by the naked costae. Styliform columella according to Beauvais (1986) but that does not appear clearly in the sample. Endotheca made of rare dissepiments and tabulae that periodically divide the lumen vertically. Wall present, probably septothecal. No synapticulae observed. FIG. 43. — Distichophyllia ? sp.: A , distal view of the specimen CPUN AM16177-5; B , specimen pictured in the field (Dades Valley, Morocco); C , transverse thin section of the specimen CPUN AML8-1; D , distal view of the specimen CPUN AM16177-9. Scale bars: A, 6 mm; B, C, D, 4 mm. Calicular diameter: 1.5 to 2.5 mm – Number of septa: 32 to 36 – Septal density: 3 to 4 for 0.5 mm . SIMILARITIES AND DIFFERENCES Differs from the other taxa of the genus Stylosmilia Milne Edwards, 1848 by the lack of auriculae. With the doubt concerning the presence of a styliform columella we choose to maintain the species under the genus Stylosmilia (with quotation marks) even if the genus Proaplophyllia Roniewicz, 1976 would be more appropriate in case of lack of columella.
