Characters: Colonies are massive, usually small. Corallites are crowded, usually circular and monocentric but rarely becoming elongate and polycentric. Septa are thickened over the corallite wall and exsert, with large teeth near the wall. Paliform lobes may form a crown around the columella. Columellae are small. Colour: Usually pale brown. Similar species: Favia matthaii, which has thinner septa, less development of a paliform crown and smaller septal dentations. Septal dentations are sufficiently long to be Acanthastrea-like (Mussidae). Habitat: Upper reef slopes. Abundance: Uncommon.
