Comments. This specimen was recognized based on the interradial paired plates, as well as marginal actinal and adambulacral plate morphology. The thin layer of tissue on this specimen was absent as were any granulation or spination. However, the pedicellariae which is relevant to identifying Anthenoides epixanthus was absent from the surface and no pedicellariae traces or pitting on the individual was observed. Arm shape and body thickness of this specimen was also diagnostic of A. epixanthus . Although collected in New Zealand, this represents one of the easternmost observations of this genus and species.

Mecho et al. (2019) observed several individuals of a red goniasterid, which, based on its arm and disk shape appears to be Anthenoides . Image quality did not permit species-level identification, but if the video observations are consistent with the collected specimen, these could be Anthenoides epixanthus .

Occurrence. Rapa Nui, Hawaiian Islands , Japan, New South Wales Australia, New Zealand. 100– 591 m.
