Anthenoides cristatus

The species was originally described as Leptogonaster cristatus by Sladen in 1889. Anthenoides tenuis Liao & A.M. Clark, 1989 is considered a junior synonym of A. cristatus, as both share short, conical spines on the inferomarginal plates and a range of 4–7 furrow spines.^[1]

The species has a stellate body with triangular arms and weakly curved interradial arcs. The abactinal surface is composed of polygonal plates covered by a dermis and round to irregular granules, especially distally adjacent to the superomarginal plates. Abactinal, forceps-like pedicellariae are present. Superomarginal plates are covered by dermis and are abutted distally approximately 4 to 6 plates from the terminus. Inferomarginal spines are present, especially on proximal plates. The actinal regions are covered by dermis with sparse granules. Furrow spines number 4 to 7, are widely spaced, and are blunt with pointed tips. Subambulacral spines number 2 to 3, are short (approximately half the height of the furrow spines), and are accompanied by tong-like pedicellariae, especially proximally.^[1]
