Species group: echinata  .

Description. Colony outline: indeterminate, predominantly hispidose. Branches: tertiary branching order present; length: 25–50 mm; diameter: 5.0–9.9 mm, 50/50 axial/radial, terete; radial crowding: not touching; axial/radial ratio: <1:10. Axial corallites: two synapticular rings; not porous; outer diameter 1.5–2.8 mm; inner diameter 0.5–1.3 mm; primary septa to ¾ R. Radial corallites: medium; two synapticular rings; one size or graded; inner wall developed; shape: appressed tubular; openings: oval-rounded; primary septa to ¼ R. Coenosteum: same on and between radials: dense spinules; spinule shape: elaborate.

Taxonomic note. Acropora navini  is placed in synonymy with A. longicyathus because the holotype falls within the range of variability of the specimen holdings above: in particular, with G39737, G57529 and G57994, all from the Great Barrier Reef.
