Diagnosis
ReferenceDiagnosis
D. B. Blake 1984A subfamily of the Benthopectinidae in which the abactinal skeleton consists of a large number of flat or low conical disc-like ossicles with a central spine base, digitate subcircular outline; ossicles relatively large, uniform in size, arranges in well-defined rows, overlap adjacent ossicles to form continuous pavement. ambulacrals low, ambulacral body very elongate, attenuated triangular in outline, producing large podial pores; marginal brace not developed at abradial end of ambulacral abactinal ridge; enlarged distal ambulacral/adambulacral articular surface not developed. Adambulacrals either quite short, subvertical in orientation with transverse row of spine bases or elongate, subhorizontal in orientation, with single large spine base.
