SUMMARY
Colonies are encrusting, multiserial and sheet-like. The ancestrula and early astogeny have not been described.
Autozooids are small, measuring about 0.32-0.42 mm in length by 0.26-0.36 mm in width, and have a rounded rhomboidal outline shape, with raised boundary walls, those around the proximal perimeter being conspicuously concave and the distal perimeter convex. The frontal wall is an extensive cryptocyst which is depressed, slightly convex and granular. Gymnocyst is lacking. The small opesia is semielliptical, transversely elongate, about 0.09 mm long by 0.16 mm wide, with opesiular indentations in the proximolateral corners between which the proximal edge of the opesia is bidentate. There are no oral spines. Ovicells are hyperstomial and have a granular, cryptocystal surface similar to the frontal wall in texture, a fissure separating the ovicellular calcification from that of the maternal zooid.
Avicularia are lacking.
