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 Benthopectinidae in which the abactinal ossicles are varied among taxa, including flat typically scale-like ossicles; simple paxillae; stout tabulate paxillae; or simple columnar ossicles; basal digitations generally lacking and present in few ossicles on an individual where developed; abactinals of different sizes intermingled, not aligned in clearly defined rows. Ambulacrals high, ambulacral body moderately elongate, rectangular in outline, with moderately large podial pore, marginal brace developed on abradial of abactinal ridge of arm ossicles in most species, distal ambulacral/adambulacral muscle surface very large, in life linked to similar surface on adambulacral. Adambulacral long, orientation subhorizontal, with angular furrow margin, prominent spine bases.|
