Species group: robusta.
Description. Colony outline: determinate, predominantly arborescent-table. Branches: tertiary branching order absent; length: 5 0–100 mm; diameter:>19.9 mm, axial-dominated, tapering; radial crowding: some touching; axial/radial ratio:>1:10. Axial corallites: two synapticular rings; porous; outer diameter 2.0–2.5 mm; inner diameter 0.7–1.2 mm; primary septa to 2/3 R. Radial corallites: large; two synapticular rings; two sizes; inner wall developed; shape: tubular; openings: dimidiate; primary septa to 1/3 R. Coenosteum: different on and between radials: between radials: reticulate, on radials: costate; spinule shape: single point.
Taxonomic note. It is possible that Acropora rotumana may be taken out of synonymy with A. abrotanoides, following the finding of ‘populations’ of a colony form, dubbed the ‘Pacific elkhorn’, in Arno Atoll in the Marshall Islands (Richards et al. 2010). This form, identified from its colony structure as probably a more mature form of A. rotumana than that exhibited by the holotype, showed some separation from other forms of A. abrotanoides in genetic analyses using nuclear (Pax-C) and mitochondrial (rnscox3) gene regions. The authors considered that additional material from the type locality should be compared with the Arno Atoll material before any taxonomic decision is made.
