Diagnosis Antedon with centrodorsal hemispherical, more or less flattened, with fairly large convex polar area. Cirri 15-30, short (usually about a fifth of arm length), 7-8 mm long, of 12-14 cirrals, distally gently recurved and somewhat flattened and wider; longest with L/W ratio ~2; decreasing distally; antepenultimate with L/W ratio ~1.5. P1 of 10-13 segments; P2 of 7-10 segments and about half as long as P1; P3 larger than P2. Arm bases making less than a right angle with the oral-aboral axis, at least when arms not fully extended. Arms 20-70 mm (usually 30-35 mm).
The relatively longer cirri, which are not strongly flattened and recurved distally and have longer distal segments, the more or less hemispherical centrodorsal, the smaller P1 with fewer segments and the absence of the characteristic flattened appearance distinguish this species from the other south Australian form, A. incommoda.
