Placement of genera not studied (studied genera in bold) was based on morphological similarity and/or biogeography, and should be regarded as provisional. Names of genera taken from recent analysis of extinction risk [24], which categorized species as data deficient (DD), least concern, or levels of increasing threat [near threatened (NT), vulnerable (VU), endangered, and critically endangered]. In this table, percent of species lacking adequate data, percent of species with moderate (NT or above) and high (VU or above) risk are indicated. Family abbreviations (all capitals) and clade roman numerals are as in Figure 1.
Some Pachyseris (particularly P. gemmae and P. rugosa) may be cluster with remainder of Agariciidae in Clade VII.
Based also on other analyses [21].
Based on unpublished CO1 data.
Based on Fig. 2.
Includes Indophyllia (pers. obs.).
