Figure 5. The strict consensus of 39 final trees. Synapomorphies for each clade in the ingroups are indicated by solid bars: lunulitiform colony (1), encrusting colony (1¢), ancestrular attachment without cementation (2), subtatiform ancestrular frontal wall (3), gymnocystal foramina (6), lack of well-formed costae (8), zooid deeper than length (12), undifferentiated proximal corners of orificial anter (13), indented proximolateral corners of orificial poster (15), vestigial excavations in gymnocystal surface (16), small excavations in gymnocystal surface (16¢), lack of medial suture in proximal rim or orifice (18), maternal orifice slightly dimorphic (19), endozooidal brooding of embryos (20), two kenozooidal foramina (22), one central plus two small kenozooidal foramina (22¢), interzooidal communications with pore-chambers (25).
