Parasimplastrea sheppardi

Veron, 2000

Colonies are encrusting to submassive. Corallites are 4-6 millimetres diameter. A ?groove and tubercle? formation may be present, but corallites are cerioid to subplocoid, retaining individual walls. Septa have smooth or slightly serrated margins, are widely spaced, and plunge steeply within the corallite. Columellae are rudimentary, consisting of thickened inner septal margins. Polyps are fleshy.

Colour: Brown with greenish calices.

Habitat: Reef environments.

Abundance: Uncommon.

Similar species: Blastomussa merleti , Leptastrea bewickensis

Taxonomic note: Taxonomic note: This genus is moved from Family Oculinidae because of general similarities with Leptastrea bewickensis and the occasional occurrence of septal serrations and rudimentary columellae. The species was formerly called Parasimplastrea simplicitexta (Umbgrove, 1939). This is an extinct fossil faviid with larger corallites and different septal structures. Source reference: Veron (2000). Taxonomic reference: Sheppard (1985, as Parasimplastrea simplicitexta), Veron (2002). Additional identification guide: Sheppard and Sheppard (1991, as Parasimplastrea simplicitexta).
