Characters: Colonies are massive to encrusting. Corallites are rounded and clearly plocoid, with thick walls. Corallites are often uniformly inclined on the colony surface. Septa are in two indistinct orders, primary septa being numerous and equal. ‘Groove and tubercle' formations are rare.
Colour: Cream with dark calices.
Similar Species: Leptastrea inaequalis, which has barrel-shaped corallites and six exsert primary septa and L. bottae, which has more compacted corallites and exsert primary septa. See also L. transversa.
Habitat: Shallow reef environments.
Abundance: Rare, except at Cocos (Keeling) Atoll.
Taxonomic Note: Becomes difficult to identify in shallow exposed habitat when corallite walls become thick. This resembles similar morphology in an undescribed species.
