Colonies are massive and more than one metre across. Corallites are irregular in shape, with 1-3 centres. Walls are thick. Septa are evenly spaced and strongly alternate with short septa developed only near the corallite rim. Paliform lobes are poorly developed or absent. Columellae form distinct centres. Fleshy polyp tissue forms a distinctive rim above the theca giving a subplocoid appearance.
Taxonomic note: The generic designation is arbitrary as paliform lobes, usually characteristic of Goniastrea, are poorly developed. Source reference: Veron (2000). Taxonomic reference: Veron (2002).
