An annelids’ theory of myzostomid origin is reviewed, and a comparative morphological and embryological diagnostic traits of myzostomids are described. The analysis of these traits gives evidence of myzostomid closeness to molluscs and dinophilids than to annelids. Among Trochozoa two new groups of superphylun level are distinguished: First one Trochozoa oligomera include the most primitive trochophore animals – phylum Mollusca, phylum Myzostomida and class Dinophilida that have larval body only. Second group Trochozoa polymera includes phylogenetically more advanced phylum Annelida and phylum Arthropoda with body that have both larval and postlarval segments. There is created new phylum Myzostomida with description of its diagnosis. The differential diagnosis for each order and families of myzostomids are described.
