The type and cotypes of Paraparchites humerosus are described and figured. The original figures were based on unrecognized nested molts. The hinge is shown to be fairly simple. A velate structure along the ventral margin, as indicated in the original illustration, is shown to be nonexistent. A new family Paraparchitidae and superfamily Paraparchitacea are proposed to include certain paleocope ostracodes.
