During the mid-20th century, it was briefly suspected that the ctenothrissiforms could be a Lazarus taxon that survived to the modern day, based on the discovery of specimens of the deep-sea fish "Macristium", which closely resembled the extinct Ctenothrissa. However, further discoveries of "Macristium" specimens proved that this genus actually represented the larval form of the aulopiform Bathysaurus, refuting the speculation over surviving ctenothrissiforms.[4]

Some authors instead place the families of this order within the Myctophiformes,[5] while others keep Ctenothrissidae and Pattersonichthyidae within the Ctenothrissiformes, but move Aulolepidae to the Myctophiformes,[3] or consider the Pattersonichthyidae to be indeterminate acanthomorphs.[6]
