Classification
Remarks
According to Alloiteau ( 1958, p. 101), the genus Plesiocaryophyllia is distinguished from other forms of the Caryophylliidae by the presence of both a pali crown before S2 and a fasciculate columella. Re-study of the holotype of the type species of Plesiocaryophyllia by Baron-Szabo in 2005 revealed that it has a columella that consists of trabecular segments and that its septal arrangement is in 8 systems (the latter feature was also described by Alloiteau). The type of columella seen in Plesiocaryophyllia is typical of the kind in Caryophyllia. In addition, the genus Caryophyllia is also characterized by the occurrence of pali before the 2nd group of septa when hexameral symmetry is lost, which is the case in Plesiocaryophyllia. Therefore, the synonmy with the genus Caryophyllia is suggested.
Distribution
