Asteroidea - Notomyotida - Benthopectinidae
If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|D. B. Blake 1984||A 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.|
