Note
Copidaster lymani A. H. Clark, 1948, is reported and redescribed from new material collected at Carrie Bow Cay (Belize), Portobelo (Panama), and Ascension Island. These are the first western Atlantic records of C. lymani since description of the holotype from Florida. Revisions by earlier authors, in which Copidaster is synonymized with the genera Leiaster or Ophidiaster, are rejected, and Ophidiaster schismochilus H. L. Clark, 1922, is referred to the genus Copidaster.
