Description In addition to the type species, described and illustrated by Alloiteau 1958, other descriptions concerning the genus are known. In the Callovian of Tunisia, Beauvais 1966: 19, pl.1, fig.7 described and illustrated P. soltanensis. The northernmost site of the genus is Scottland, Navidale, where Kimmeridgian deposits occur containing Oxfordian coral clasts, among others the corals determined as Enallocoenia callomoni by Beauvais 1977: pl. 1, fig. 3a-c, presenting typical features of Pseudodiplocoenia. Portlandian species, P. oblonga (Fleming, 1827), described and illustrated in Roniewicz 1970:527,text-fig. 3-5; pl. 2, fig. 1-3; pl. 3, fig. 1-3; pl. 4, fig. 1-4, based on thin sections, provided with the most complete information on the genus.

Comparison In external morphological features similar to Connectastraea Koby, 1905. In the fissure observed in the middle of the wall, and in eccentric axial pit, Pseudidiplocoenia is somewhat similar to Amphiastrea from which it differs, as well as from all amphiastreid corals, in the microstructure of septa and in the way of budding. From microstructural point of view, the genus has no counterparts and for this reason it falls into the cathegory of genera of uncertain position.

[details] Diagnosis Corallum cerioid; wall tectiform; septal arrangement radial-bilateral, anastomosis among the S2 septa and S3 septa; septal sides with oblique ranges of sharp granules, internal border regularly denticulated; columella of septal origin, rudimentary, eccentric; endotheca made of large, oblique, peripheral dissepiments and rare, horizontal pseudotabulae traversing the lumen; increase by septal division of the adult calice into 2-4 descendant calices. Microstructure: trabeculae thick, set off from the wall at obtuse angle and then declining toward the corallite axis; thick mural spines of radial structure compose the wall; stereomal peripheral deposit makes the upper dissepimental layer massively thickened. Remark: If the centers of mural spines are dissolved, a characteristic fissure appears at the middle of the wall that resembles that observed in the colonies of Amphiastrea. [details] Remark Three or four species are known. [details] |
