Plagioeciidae Canu, 1918

According to Taylor (1993), this is synonymous with the Diastoporidae, used in other accounts. Taylor prefers the Plagioeciidae, stating that "the name Diastoporidae is best avoided because of its common usage for tubuliporines lacking brooding zooids." While this emphasises the need for revision of many (most) cyclostomes, the Diastoporidae appears to be still available for genera which may be related to the type species of Diastopora, D. foliacea.

However, this is not an appropriate place to suggest changes to current systematic practice. The genera in the list below are most of those included in either of these families in past accounts - except for Diastopora and Berenicea , which is not recognisable. There are some problematic genera in this list, which should be separated into the group of "unattached" genera until they are better known (if ever).

Note: 18 October 2001. Taylor & Gordon (2001) have redescribed Liripora, assigning the genus to the Diastoporidae, also including Mesenteripora and Desmeplagioecia in that family.

Note: 30 January 2007. Taylor & McKinney (2006) included the genus Mesenteripora in the family Plagioeciidae.

Note: 19 October 2010. Gordon & Taylor (2010) observe that the family Plagioeciidae is in a major clade with the Disporellidae and Lichenoporidae, while a second major clade includes genera such as Cardioecia, Diplosolen, Frondipora, Entalophoroecia and the Horneridae. The type species of Diaperoecia is a fossil form that seems to be closer to this second clade. The families Plagioeciidae and Diaperoeciidae are therefore kept distinct. The current view is that Liripora and Desmeplagioecia are best placed in the Plagioeciidae.
