If Amphiaspidida can be ignored as a daughter-taxon, the family Ctenaspidae contains Ctenaspis and its various sister-taxa originally contained within both Ctenaspididae and Ctenaspididae, including Allocryptaspis, Alainaspis, Zaphoctenaspis, Arctictenaspis, and Boothiaspis, which was first described as a "Canadian amphiaspid."[1]
