Comparison Like Acanthogyra but columella absent and corallites are generally in a greater variety of integration types (phaceloid to cerioid and subcerioid to meandroid integration). [details]Diagnosis Colonial, phaceloid-cerioid, subcerioid-meandroid during the initial stage of septal division. Gemmation intracalicinal, marginal, and/or by septal division. Septa, compact, thick (S1) or thin (S2 and higher), alternating in length. Numerous lonsdaleoid septa present. Columella absent. Wall septothecal-trabecular. Endothecal dissepiments subhorizontal in corallite centre, vesicular in the periphery. [details]
Remark Generally, the polyps of Acanthogyra are in cerioid integration. However, studies carried out by Lauxmann (1991, p. 193) on the type material of the type species of Acanthogyra showed that, besides plocoid-meandroid integration types, polyps in phaceloid-fasciculate arrangements are present as well. In addition, Lauxmann cleary pointed out that even in the best preserved polyps in the holotype of the type species, a columella was often not present. On the other hand, in Paraacanthogyra trabecular extentions of axial ends of septa reach the corallite center where they form a segment-like pseudo-columella, thus indicating the close relationship with Acanthogyra. It seems possible that Paraacanthogyra represents a morphological variation of Acanthogyra and might not have the generic independence from the latter. [details]
