Classification Placed in family Plicatocrinidae by Clarke & Johnston (2003). [details]Diagnosis Hyocrinidae with 5 unbranched arms; proximal arm pattern usually 1+2 3 4 5+6 7+8 or 7 8+9 with first pinnule on Br4, or on Br5 with 1+2 3 4+5. Four proximal brachials nearly equal in height and width. Pinnules relatively rigid without both conspicuous genital expansion and H-shaped plates; lateral plates of the same size or smaller than cover plates, and number and extension in proximal pinnule variable. Tegmen moderately to highly inflated with moderately sized orals and variable anal cone close to oral cone. Aboral cup usually smooth, rarely with small transverse ridges; primibrachials about 2/3 radial width; basals three or usually fused. Stalk symplexies with 6–9 crenular units; distal syzygies frequently with well-developed crenularium. [details]
