Characters: Colonies are smooth massive boulders up to 1.5 metres across. Corallites are uniform, 3-5 millimetres diameter with well defined walls. Septa are in two distinct orders of 6-8 and are exsert. Paliform lobes are inconspicuous. Columellae are small.
Colour: Red to orange, usually with green centres.
Similar Species: Plesiastrea versipora, which has more septa and conspicuous paliform lobes.
Habitat: Shallow reef environments.
Abundance: Seldom common.
Taxonomic Note: Little known species. Called Plesiastrea devantieri (= Astrea devantieri) in Veron (2000a) and Veron (2002a). Astrea devantieri was retained by Huang, Benzoni, Fukami et al. (2014) as a separate ‘sister’ species, but the holotype of Plesiastrea devantieri is unambiguously this species.
