Diagnosis
ReferenceDiagnosis
A. d'Orbigny 1850 (Pentetagonaster costata)A species in which each marginal plate has a central keel on the outer face.
G. Breton 1992Metopaster of relatively large size. Outline circular to pentagonal with convex sides. Six intermediate superomarginal plates per side. Marginals plates wide. Superomarginals with a rounded abactinal dome and an abradial side close to vertical. Profile of the inferomarginals regularly convex. Width of inferomarginals highest in the interradius decreasing progressively to the tip. Enlarged ultimate superomarginal plates triangular, wider than long, sometime dissociated in two separate plates. Enlarged ultimate superomarginal plate in contact with three to six inferomarginal. Granule-pits distributed in variable manner on the central area but clustered or denser on the abradial side of the inferomarginal and the abactinal dome of the superomarginal plates. When present, pedicellariae pits of wing-shape type.
