    Etymology


    The Macrocephalitidae is one of the 11 families listed in the Treatise, 1957 Part L in the superfamily Stephanoceratoidea.
    According to Donovan et al. (1981) the superfamily Stephanoceratoidea should contain only five families and the Macrocephalitidae of the Treatise are reduced to subfamilies within the Sphaeroceratidae, Macrocephalitinae and Mayaitinae, but still in the Stephanoceratoidea.
