Branches: tertiary branching order absent; length: 2 5–50 mm; diameter:>19.9 mm, axial-dominated, tapering; radial crowding: most touching; axial/radial ratio:>1:10. Axial corallites: two synapticular rings; porous; outer diameter 1.3–4.0 mm; inner diameter 0.6–1.0 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 2/3 R. Coenosteum: different on and between radials: between radials: reticulate, on radials: costate; spinule shape: single point.

Taxonomic note. In Wallace (1999), A. diomedeae was accidentally included as a synonym of A. nasuta as well as A. listeri. After re-examination of the type specimen (by C. Wallace.), this species is removed from the synonymy of A. nasuta and confirmed as a synonym of A. listeri.
