Deep-sea Fauna of European Seas: Asteroidea
IdentificationRemarks: The genus Hymenasterides consists of two species. The most significant differences between H. zenognathusfrom West Pacific and H.mironovi from Atlantic are the following: 1) only five to seven spines per paxilla (instead of 9–25) and2) adambulacral plates

IdentificationRemarks: According to Clark, Downey (1992) and Mah (2014), H. membranaceus is considered to be a junior synonym of H. pellucidus. A.M. Clark(1996) and Dilman (2013) assigned H.membranaceusto a distinct species.
