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.

A. Y. Ivantsov and R. Wrona 2004Long, slender, cylindrical annulated worm without parapodia, covered by paplilate epidermis with cuticle. The papillae (tubercles) are arranged in transverse double rows separated by an intercalation or
furrow accentuating their annular surface pattern. The epidermis may form sclerotized cuticular structures, button-like phosphatic sclerites covering the entire body as an armour. Sclerites may be differentiated in size and ornamentation; the largest are plates, equal in size, circular or sub-circular with prominent nodes on the upper surface, and similar to but smaller than plates are platelets, which can be accompanied by much smaller microplates of simple morphology.
