Species group: humilis.
Description. Colony outline: determinate, predominantly corymbose. Branches: tertiary branching order absent; length: 2 5–50 mm; diameter: 10.0–19.9 mm, axial-dominated, terete; radial crowding: not touching; axial/radial ratio:>1:10. Axial corallites: three synapticular rings; not porous; outer diameter 2.7–4.5 mm; inner diameter 0.8–1.8 mm; primary septa to ¾ R. Radial corallites: medium; three synapticular rings; two sizes; inner wall developed; shape: tubular; openings: oval-rounded; primary septa to ¼ R. Coenosteum: same on and between radials: reticulo-costate; spinule shape: elaborate. Taxonomic note. Acropora torresiana is placed in synonymy with A. samoensis based on comparison of the holotype with G2959 0 from Wye Reef and G28230 from Osbourne Reef from Veron and Wallace (1984). We concluded that the A. torresiana holotype is an immature and rapidly growing example of A. samoensis.
