ReferenceDiagnosis
G. D. Webster and N. G. Lane 1987Calyx low to moderately high, bowl- to cone-shaped, tegmen convex, bearing subcentral anal tube; basal circlet low, distal tips upflared, visible in lateral view, RR largest plates in theca, primanal in radial circlet followed by 2 plates; IIBr axillary, rarely 2 IIBrr per ray; fixed brachs commonly including IIIBr i to IIIBr 3 ; arms strongly grouped into protruding lobes, some lobes beginning with IIBrr or IIIBrr; free arms 4 or 6 per ray at thecal rim, in some branching distally, uniserial proximally, biserial distally; iIBr number variable, commonly 5 to 7 below ambulacral tracts, in contact with tegmenal plates distally; iIIBrr present or not; tegmenal plates small, undifferentiated; anal opening at distal end of slender anal tube. Stellate ridge and ray ornamentation common on theca, nodes or short blunt spines common on some tegmenal plates. Stem round; lumen pentalobate.
