Classification

Remarks

According to Reig Oriol (1989, p. 8), the genus Pachynefocoenia is a plocoid colony that has compact costosepta in both radial and bilateral arrangement; septothecal and synapticulothecal walls; extracalicinal budding; twisted columella; tabulate exotheca. However, the images and figures of the type specimen cleary show a colony that is massive but also has polyps that are in subfasciculate (no lateral connection between some of the corallites), plocoid or subplocoid integration. In addition to extracalicinal budding, the presence of intracalicinal multiplication, that leads to a submeandroid polyp integration type, can be observed. Moreover, the skeletal structures that, according to Reig Oriol, are supposed to show synapticulothecal developments, rather indicate septothecal to septoparathecal walls, thus very closely corresponding to Barysmilia. Therefore, their synonmy is suggested.
