Checked: verified by a taxonomic editorDiagnosis Test and spines typically black with a red tinge and a turquoise sheen when viewed in direct sunlight. The iridophore pattern occurs as bold blue lines down either side of the naked interambulacral areas, as a pentamerous ring around the apical disc and as lines along some plate boundaries. Apical disc is hemicyclic with arch-shaped depressions on the denuded genital plates in both adults and juveniles. Gonopores measure 33% of the length of the genital plates. The periproctal cone is black with no markings. The Peristome is proportionally large measuring 40–60% of the test’s horizontal diameter. Spines are verticillate and hollow with distal barbs. Verticilations are formed of urn-shaped solid wedges that are visible when the spines are viewed in transverse section. These wedges typically number twenty in ambulacral spines and twenty-four in interambulacral spines. Only tridentate and triphyllous pedicellariae are present. The tridentate pedicellariae occur as a single form with reasonably broad, curved valves, with almost straight edges, that can either be smooth or serrated, with an expanded distal gripping region. The blades of the valves meet only along the upper fifth of their length. The head of each pedicellaria is supported by a long muscular neck, attached to a mid-length stalk. [details]
